In this series, we offer a critical review in French, in several parts, of the popular science book "The All-road bike revolution" by Jan Heine (2020). Heine is renowned as a pragmatic innovator credited with several important technological developments seen on contemporary all-road and gravel bikes. He is also the founder of René Herse Cycles and editor of Bicycle Quarterly magazine.
The All-road Revolution
The central idea that Heine argues throughout the book is that the contemporary all-road bicycle transcends the traditionally established categories of road, touring, and mountain biking. Except in the most extreme cases and for the most extreme uses, these machines are now capable of offering both performance and comfort on tarmac, mixed surfaces, or trails. It is worth noting that the author retains the term "all-road" because he considers the designation "gravel bike" to be loaded—indeed, these bikes are not, in his view, confined to gravel or dirt roads as the term might suggest. Ironically, the opposite argument could be made regarding the term "all-road," whose use is no longer limited to paved roads.
Beyond this almost rhetorical questioning, the core of Heine's argument is striking: it would indeed be a "revolution" in that it is not only the technologies of bicycles that have evolved, but also in the uses made of them; just as much in international sports organizations as for you and me, a breaking down of barriers of minds, communities and practices is indeed taking place.
The modern all-road bike is comfortable, high-performing, and versatile. Over the years, the compromises a cyclist has to make when choosing their bike have become increasingly minor:
“In the past, we thought that choosing performance meant abandoning the aspiration for comfort or versatility. We have now found that this was wrong: comfort is directly linked to performance. This means that performance is accessible to everyone, or more precisely, to those who are willing to suffer for a little more speed. It is in this realization that the revolution in bicycle design we are discussing originates, for the benefit of all.” (Heine, 2020, p. 8)
Choosing your All-road bike
Heine suggests choosing your all-road bike by prioritizing certain aspects and components. First and foremost, he recommends focusing on the tires the frame can accommodate: this component is the only point of contact with the ground, in addition to providing minimal air suspension upon which comfort and performance depend. A 42mm diameter tire is now the standard (and a constantly increasing one) and allows for balanced handling. While sporting tradition has led us to believe that a narrower tire is faster, this bike demonstrates that this is simply not the case. On the contrary, Heine argues in favor of the largest possible air volume, which is more comfortable and therefore more efficient, and ultimately safer.
The riding position, linked to the frame size and geometry, is the second most important factor when choosing an all-road bike, according to Heine. Many manufacturers now offer a variety of all-road and gravel bike models with varying degrees of aggressive geometry, allowing for more precise handling with optimized aerodynamics on the one hand, and improved comfort and stability on the other, even when loaded with luggage. The bike's fork also plays a crucial role. In a variety of multi-surface riding situations, the fork's flexibility will positively impact performance, rider comfort, and even safety. This also contradicts the outdated and often misconception that a stiffer fork is preferable.
Heine finally examines the factors that should determine the choice between flat or drop handlebars (the latter offering a greater variety of riding positions and better aerodynamics), wheel size (smaller wheels being more responsive), and then the correct gear ratios for the drivetrain (easier ratios are preferable). The author interestingly points out that compatibility with peripheral equipment such as fenders, racks, or integrated bikepacking bags, as well as with a high-performance lighting system, is set to become increasingly important as our understanding of what an all-road bike should be capable of evolves throughout this revolution.
Even more surprising, Heine writes that he places little importance on the other mechanical components, most of which are easy to change. The majority of mechanical component groups, he writes, are now of very satisfactory quality. The same is true for the cockpit components: the specific size and curves of the handlebars, saddle, and pedals are highly customizable items that should be adapted to one's body type and needs as a priority, whatever the circumstances. Therefore, this is not a selection criterion that he considers very important. Along with the tires, these elements are subject to change, revolving, in a way, around the "platform" that is the frame of the all-road bike, the choice of which is truly critical depending on the needs and aspirations of the cyclist.

Gravel riding in Montreal: nowhere and everywhere at once! You, aspiring urban gravel rider, did you know that the term "gravel bike" sometimes sparks controversy? For some, it's an industry conspiracy to sell more bikes. Me? I'd rather ride than argue. But these commentators do bring something interesting to the table: as an alternative to gravel bikes and adventure bikes, some have suggested calling what we do on a road bike "mixed surface."
And, thinking about it that way, Montreal can be seen as a huge, frankly more appealing playground! If you're looking for long stretches of gravel, you'll have to venture a little further from the center. But if you're ready to indulge in some creative combinations, there's a lot of fun to be had. Because that's also what urban gravel in Montreal is all about: *it all fits together well!*
Here are two ride ideas within this broad category. Local classics, ideal for getting started with urban gravel riding, and directly accessible from the city center. But above all, I encourage you to consider them as "hubs" around which you can try variations, take turns, add sections—as you see fit, depending on whether you're more of a tireless road cyclist, a repressed mountain biker, or a happy newcomer.
On the trails of Bois-de-Liesse
Joy awaits at Bois-de-Liesse (approximately 45 km round trip). Explore a vast sandy woodland with numerous winding trails, including access to the waterfront in the Peninsula sector. How to get there? Simply follow the gentle route to Gouin Boulevard, then head west for about 15 kilometers. Keep an eye out for parallel trails that cross small parks or run alongside the river. Once there, you'll find great spots for a picnic or to bring your significant other. On the Sunnybrooke side, Bois-de-Liesse also connects to the very smooth Salaberry trail, bordered by gravel, which leads to Cap St-Jacques: check it out when you're ready for more ambitious adventures! You're adding many more kilometers to your journey, but in doing so you also gain access to an even wilder natural/gravelly landscape, in addition to the famous beach :)
A feast for the eyes, by the water's edge
The TransTerrebonne route will transform you (approximately 70 km round trip). A system of winding, generously hilly trails and paths, mostly on hard-packed dirt—absolutely exhilarating! How to get there? The more adventurous will take the trails in Ruisseau-de-Montigny Park to reach the A25 bridge. Then, after crossing Laval, the TransTerrebonne entrance is just a few kilometers from charming Old Terrebonne. Whether you're going in one direction or the other, to cross Laval Island, you can choose to venture into the farmland and take the farm roads that crisscross it. Tough stuff! Or, for the even more daring, you can access the famous Underground Network (RUT) from the TransTerrebonne and enjoy the singletracks.
At high speed on the TT
Finally, Ceci n'est pas un Club, co-organized by the MTL Gravelle community and Studio Cycle Maglia Rosa , offers Wednesday evening rides throughout the summer. These free rides, with priority given to beginners, will take us, among other places, to these two introductory routes!
Every Wednesday, from July to October, meet at 6 p.m. in front of Studio Cycle Maglia Rosa , at 6393 Papineau Avenue in Montreal. A volunteer guide will be present, but each participant must be self-sufficient. Surprises and participation prizes will also be distributed as a token of encouragement!
PS Check out Gravelmap.com for more inspiration — and don't hesitate to add your own finds, there's still plenty of potential for exploration! Long live urban gravel.
The beauties of splicing, in urban gravel
Hey there, real ones. A blog by Pierre Gravel.
The author has been passionate about cycling since childhood. A former bike shop worker, he is now finishing his studies in communications. This blog reflects his independent opinion.
For today's interview, I met with a satisfied Maglia Rosa customer. Not very talkative, rather laconic, and wishing to remain anonymous, he nevertheless agreed to be temporarily nicknamed Max Powers for the purposes of this interview. He also answered a few of my questions, adding his own two cents...
Agnès M. Croteau : So, dear Max, thank you for agreeing to speak with me today. Now: basically, would you describe yourself as an athlete?
Max Powers : No.
AMC : Those who know you know that you've maintained a weight loss of at least 60 pounds for years. Do you attribute this to cycling?
MP : Yes.
AMC: ... Okay, but what else? What led you to practice this particular sport?
MP : Saving gas to get to work. It's expensive to repair a BMW.
AMC: 10-4 . Understood. So, not particularly athletic to begin with, you still went to Maglia Rosa to buy your first bike a few years ago. How would you describe your experience there? Did you enjoy it?
MP : I wanted to support a local business near us. Impeccable service.
AMC: You also appreciated it when they offered your girlfriend a free tune-up at the very beginning of the pandemic because she was a healthcare professional... It's worth following them on social media, isn't it? ;)
MP : Yes, it was a nice initiative on their part.
AMC: Tell us about your bike. Do you still love it? Do you think it rides like it did on day one? Would you ever consider getting another one?
MP: The bike is very good for my needs. [Editor's note: Norco VFR 2.] I plan to buy a road bike in a few years for longer journeys.
AMC: With your Norco, what are your best cycling trips to date?
MP: Go to the Ice Cream Master.
AMC: …
MP: Seriously, I like going to and from work.
AMC: Otherwise, where would you like to ride at the end of the pandemic ( psst : it can be anywhere in the world!)?
MP : To cycle around the Magdalen Islands.
AMC: Perfect! And, a final word for those who, like you, don't feel they have a particular predisposition for regular physical activity?
MP: You have to do sports to afford a good poutine at Claudette's afterwards!
You know what? I agree with you, dear Max. Wisdom is summed up in a few words.
With that, have a good trip! ;)
Cycling Chronicle by Agnès CroteauHealthcare professional and cycling journalist
I share with you my local discoveries, my chance encounters & the joys of being a cyclist!
Look around you, summer is almost here! If you're as crazy about cycling as we are at Studio Cycle Maglia Rosa , the first idea that came to mind for your holidays was "pedal, pedal, pedal!".
So, let's not jump on our handlebars just yet and let's see what the best places are to go on holiday on two wheels as a couple (you and your bike, of course).
Mountain biking? In mountain biking, there are some must-do activities that will make you sweat as much as they make you smile:
It's well known that Vallée Bras-du-Nord and mountain biking are a perfect match! Thanks to the quality of its trails, the area offers the best possible cross-country experience.
On one side, the Shannahan sector immerses you in a panorama with wild and grandiose appearances.
On the other hand, the Saint-Raymond sector offers a countryside ride just a few pedal strokes from the city. Don't hesitate, brave these singletracks nestled between two mountains, in a setting that nature has designed for experienced cyclists.
One last important point: the quality of the mountain huts in Vallée Bras-du-Nord is worth the trip alone.
Road cycling? If you're more the type to burn rubber, we also have some suggestions that will satisfy your need to devour the kilometers.
As its name (almost) suggests, our next route is in the Saguenay-Lac-Saint-Jean region. The Véloroute des Bleuets is a 256-kilometre cycling circuit that allows you to tour the region without dismounting.
In addition, the Véloroute offers you 3 associated networks totaling 130 kilometers of track to vary the pleasures.
If you are still not convinced, know that the Véloroute des Bleuets was a Gold Award winner at the 2014 Grand Prix du tourisme québécois, and that tourists from all over the world flock to Saguenay-Lac-Saint-Jean to enjoy this unique cycling experience.
Head to Ontario to discover the superb Sandbanks Provincial Park, and the roads that are full of pleasant surprises and landscapes to contemplate in slow motion, on your bike.
From the park, Route 12 is your starting point for a drive you'll remember for a long time. Lake Ontario, its beaches, vineyards, and countryside will set the rhythm of your day.
Forget about performance for a few moments and without thinking about it, simply live exceptional moments.
Do you like variety? Here is a route that will appeal to everyone, with very different paths to explore in a curious mood.
Built on a former railway line, the Bois-Francs Linear Park trail crosses the municipalities of Warwick, Saint-Christophe-d'Arthabaska, Victoriaville, Princeville, Plessisville and Laurierville, ending in Lyster.
Ahead of you, the 77 kilometers of cycle path blend countryside and city for an extraordinary ride.
Make your choice, put on your helmet and… enjoy the summer on your trusty bike!
Of course, most gravel roads in Quebec are located in rural areas, at least an hour's drive from the city. Many of them are former logging roads or country lanes, while others were built specifically for tourism development. That said, on a gravel bike, you're almost guaranteed to find yourself in the woods or in the middle of a field.

Indeed, being more remote, most gravel roads in Quebec see far less traffic than paved roads. Furthermore, you'll improve the air quality you breathe and enjoy greater peace and quiet and increased safety, at least with regard to accidents involving road vehicles.

On a gravel or adventure bike, you ride a little slower; the focus is more on the journey than the destination. Moreover, the scenery is there to enhance the experience, as the lush nature of the lakes, rivers, and mountains invites contemplation. And for nature lovers like you, the chance to appreciate the grandeur and tranquility of these places only amplifies the feeling of well-being experienced during the ride.

Indeed, our close proximity to nature, the absence of cars and therefore noise, often leads to extraordinary encounters with the local wildlife. Of course, you must always respect their habitat and never feed them. Furthermore, your bicycle can easily become the most efficient and least expensive way to enjoy your photo safari!

Indeed, many gravel roads or forest paths are very well maintained and with a suitable bike, adequate tire pressure and good positioning, you will not finish your rides in worse shape than after a good 100km of road, head down in the handlebars.

For many, gravel biking is a great way to improve. Wondering why? The answer is simple: a loose surface like gravel or dirt demands superior riding technique. You'll need to maintain good traction on climbs, have a better feel for the bike's behavior in corners, and increase your mobility on rougher sections. Furthermore, riding with 38c tires at 40psi on a gravel road requires significantly more effort than riding with 25c or 28c tires at 90psi on a paved road for a similar distance. This will also increase your ability to sustain a higher level of effort for longer.

Indeed, handlebar tape absorbs more sweat when we train indoors, so it's a very good idea to replace it annually. You'll improve your grip on the handlebars, get better shock absorption, and protect your handlebars.
Indeed, it's quite possible they need replacing. Worn-out cleats can cause knee pain. And, in extreme cases, they could even lead to a fall.
Indeed, cycling shorts that are more than two years old are generally less absorbent and will have lost some of their elasticity. They will therefore no longer provide the muscle support, moisture absorption, and vibration damping of new shorts. So take this opportunity to try bib shorts if they aren't already part of your wardrobe.
If you experience discomfort after each bike ride, a bike fitting consultation will be recommended. Schedule an appointment with our specialist HERE for a complete ergonomic bike fitting.
It's springtime. The sun's rays are finally warming the forest of your sporting ambitions. The birds are chirping, the snow is melting and trickling. The "cycling bear " that hibernated within you is awakening. Without a doubt, it's on the horizon: the best cycling season ever !
If, like me, you're itching to get back on your gravel bike as soon as possible, a rather annoying question arises: how do you deal with the less-than-certain conditions that spring brings?
Two strategies. First: as long as the trails and dirt roads are—at best—soggy, as long as there's a risk that the ice under your wheels will unexpectedly turn to slush and vice versa, it might seem reasonable to stick to the tarmac. It's generally safer (though watch out for gaping potholes and forgotten patches of salt). Let's call it choosing to ride gravel cautiously. There's nothing wrong with that.
Alternatively, it might be more about adapting one's driving and equipment to uneven surfaces, remnants of snowbanks, and dust-blackened patches of ice that dot the edges of the trails. Adapting to trails that are half-flooded, muddy, or crusted over... In short: to the " gnar notte" of spring.
Is it possible to convey the importance of tires in gravel biking and adventure cycling more broadly without dedicating an entire article to it? No. But to put it simply: choosing the right tires guarantees maximum performance in adapting to these challenging conditions. It's that simple. Now, while in a previous article I praised suppleness , it was a completely different logic that guided my tire choice this spring.
It was the mention, by other reviewers, of the exceptional grip of the Cinturato Gravel M (for " Mixed terrain "), by Pirelli, that first piqued my curiosity. After testing it in a variety of conditions, I can confirm that its equally exceptional grip is ideal for tackling the less-than-certain conditions of spring gravel and mud (as well as those of late autumn).
Riding a 45mm Gravel M is like feeling every pedal stroke bite into the soft ground like a tractor tire pulling you along. It's leaning the bike over, even on soft surfaces. Then it's leaning it over a little more, searching for the point where it loses traction. It's not finding it. It's expecting, with this kind of grip, that it will roll a little slower on the road. With its almost continuous center tread, I was pleasantly surprised.
Its properties result from its shape, but also from its rubber compound and casing, which also contribute to the tire's remarkable robustness. Much like mountain biking, if you don't approach uneven surfaces and obstacles with flexibility and deformation, another approach is to tackle them with robustness and confidence! The tread pattern of the Gravel M is reminiscent of mountain bike tires from the 1990s.
For this spring, I highly recommend it to daring gravel riders. Those who will at least consider jumping over hardened snowbanks without worrying too much about what might be hidden underneath. The verdict is therefore: grip and robustness, ideal for a fun and carefree spring!

Our important point: This article and video were produced before COVID-19. We are respecting social distancing guidelines. and the health measures for positioning.
During a training session at the shop last winter, I told Yannick that I hadn't had a bike fitting in almost four years, since I bought my bike. Surprised, he told me that after a certain number of kilometers ridden annually—in my case, nearly 5,000—it's a good idea to have your bike fitted every year. And for a multitude of reasons: to reduce or even eliminate certain pains, optimize overall comfort, improve performance, or reduce the risk of injury.
After 4 years in the same mold, I got a complete fit overhaul at @MagliaRosaVelo . Here's a one-minute summary of my body shape. pic.twitter.com/8GYQhiQ3Js

Learn more about On Two Wheels...
Sur Deux Roues is a Quebec-based blog for Quebecers interested in learning more about road cycling, fat biking, cyclocross, and urban cycling. With over 16,000 unique visitors per month, data verified by MRP data, Sur Deux Roues is a niche blog that connects with a community passionate about their favorite sport: cycling.
In this article, we will demystify a new category of bicycle that is increasingly present in catalogues and in the Quebec cycling landscape.
If you plan to travel here or elsewhere; leave for the day, for a few weeks, or even a few months; go to work by bike, this new feature will undoubtedly appeal to you.
Whether you prefer asphalt, gravel, or even lichen; whether you want to ride fast sometimes but also take it easy at other times, or you simply want to stop wondering and discover a bike that would allow you to go in all directions, whatever your mood or need at the moment.
This Swiss Army knife of pedals – which would allow you to climb the forest roads of northern Quebec, travel the west coast from Vancouver to San Diego with your equipment or simply do a 100 km ride with friends in the Joliette area – exists!
It is sometimes called an "adventure bike," sometimes a "gravel bike," others refer to it as a "light touring bike," but the result remains the same: a bike whose only limits will be those you set for yourself!
The demands of road cyclists have shifted in recent years, with the majority now viewing the sport as a recreational activity – their priority is enjoyment. As we know, comfort is an integral part of that enjoyment, unless one has masochistic tendencies (which we respect), hence the growing popularity of endurance road cycling.
Then the term versatility appeared: people wanting to be able to ride both on the road and off the beaten track, with the same bike.
Depending on your budget, you can get an adventure bike made from most known materials, whether it's steel or... titanium , aluminum or even carbon.
Studio Cycle Maglia Rosa offers 5 options in the field:
Orbea Terra H30 (Aluminum) | Salsa Vaya (Steel) | Rondo Ruut Al1 | Al2 (Aluminum) and Chapter2 AO (Carbon)
Yes, it's now possible to get a high-performance adventure bike with disc brakes that weighs less than 20 pounds! That's a far cry from the heavy triple-chainring touring bikes made several years ago!
Defying all conventions governing the style and design of road bikes, the adventure bike offers possibilities that no other bike has been able to offer until now.
Technically, this type of bike shares the geometry of an endurance road bike, with a slightly more upright cockpit, longer chainstays to increase comfort, and a relatively low center of gravity to increase stability.
Also, the traditional rim brake system is being replaced by the disc brake inherited from mountain biking.
For two reasons: the first is physical – a tire wider than 28mm would not fit in a traditional brake caliper; the second is environmental – the increased dust in off-road riding would accelerate the wear of the brake pads and rim.
Since the disc is less sensitive to these elements, it is ideal in these conditions and also offers powerful braking with very high modulation.
This modification also offers the possibility of installing wider tires, from 28mm to 40mm, smooth or semi-knurled, which allows a higher air volume, thus making it possible to ride on irregular surfaces without suffering excessively.
Finally, the overall robustness of the bike is calculated to meet the specific constraints of off-road riding: more robust wheels, tear-resistant casings for the tires and a frame more resistant to impacts.
Not quite. The geometry of a cyclocross bike is generally much more aggressive and wouldn't usually allow for pain-free long-distance riding. While some do use them for that purpose, the emergence of adventure bikes makes them much better suited to long distances.
Confusion ?
As for equipment, forget about luggage racks, they're heavy and cumbersome; from now on, companies like Arkel , manufacturing its bags right here in Quebec or Apidura offers lightweight and durable self-supporting bags, so you can bring all the necessary equipment for multi-day trips without excessively weighing down your ride.
So, if you have plans for a two-wheeled trip or want to go on an adventure this summer, come see us for advice, a bike and/or the best equipment on the market to make your journey a success.
Finally, remember that the journey is always more important than the destination!
The most appreciated aspect of this discipline is the contact with nature and the absence of traffic, a real breath of fresh air, plus the variety in the courses is easier to obtain.
However, finding water or supply points is less easy, so plan accordingly. Access for emergency services in case of an accident can also be difficult, so extreme caution is advised.
It's a sport in its infancy; the network of trails is still being explored, word of mouth is key to finding your next weekend destination, and searches on Strava Or RidewithGPS We can also help you, or you can try blindly with Google Maps.
There are more and more events with a high percentage of gravel roads, with conditions that put the human body to the test.
Here is a mini list, some of them are very far away, however the first on the list is local and very well known.
100 B7 | Battenkill | Rasputista | Grinduro
The story goes that the name Chebacco comes from a road of the same name in Ipswitch, about fifteen kilometers from the Parlee Cycles offices. This road is notorious for its extremely poor asphalt. Don't bother looking for it on Google Street View; it doesn't even appear. Getting back to the point, when the Parlee Cycles team was working on developing a gravel bike, they decided their goal would be to create a bike capable of handling this bumpy road.
With disc brakes, a wide set of tires (up to 40 mm) and a 100% carbon fiber frame, with precise molding to better absorb vibrations, this bike has allowed us to expand the possibilities of off-road riding, both on four-wheel trails and mountain bike tracks.
In Quebec, cycling is a seasonal sport for most cyclists, which is why bike shops are busiest from March to July. Bring your bike in early or schedule your appointment HERE. During your visit, you can even discuss with the technicians the various components that could be improved to enhance your cycling experience.
The months have flown by, the rich holiday meals are a distant memory, and the cycling season will soon begin, weather permitting! It's time for resolutions; you're determined to smash your personal bests or train to be in peak condition for your competitions! Besides following a training plan, what else can you do? Eat well, stay hydrated, sleep well… and take vitamin and mineral supplements? The first three points are obviously essential, regardless of your fitness level, for maintaining a healthy lifestyle.
Vitamins?
Vitamins are micronutrients. The body doesn't produce them, so we must obtain them through our diet. As the name "micronutrient" suggests, the body doesn't need large quantities of them; however, they are essential for the proper functioning of our organism. It's important to know that there are two main groups of vitamins:
Therefore, you will understand that if you have a varied diet, in quantities corresponding to your physical activities, you will not be deficient in any vitamins.
Which vitamins should we take?
In Quebec, the most common vitamin deficiencies observed are in vitamin D, because it requires exposing the hands, arms, and face for 10 to 15 minutes a week, between 11 a.m. and 2 p.m., without sunscreen, from April to October, for a healthy adult. The other deficiency is in vitamin B12, which is thought to be due to an intestinal absorption problem that can vary with age, the use of antacids, and genetics, assuming that daily intake is met. Many people like to take vitamin C in winter, as it is believed to help their immune system stay strong against nasty seasonal viruses. While an intake of 500 mg to 1000 mg per day for a healthy adult doesn't guarantee a full recovery, it certainly can't hurt! There's no need to take more; your body will eliminate the excess in your urine! People who take vitamin B supplements often say they feel less stressed and more energetic. Indeed, it's well-known that B vitamins can give us an energy boost. Their use is widespread.
Who are they intended for?
That said, there are a number of people who could benefit from supplementation because they are at risk of deficiency, even with a varied and balanced diet. This includes those with intestinal absorption problems (e.g., people with uncontrolled Crohn's disease, intestinal malabsorption syndrome, celiac disease). It also includes people following a vegan or vegetarian diet, for whom a medical evaluation and follow-up with a nutritionist would be ideal to ensure appropriate supplementation and avoid unnecessary spending on products that offer no added value compared to a healthy diet. Some medications can limit the absorption of vitamins and minerals, women with heavy menstrual bleeding may be iron deficient, and finally, certain sports are known to contribute to gastric problems, such as running and cycling.
It's generally agreed that no amount of vitamins will dramatically improve your athletic performance. You might feel better, but your diet and consistent training will be the key to success. If you have any doubts that your health requires professional advice, it's better to consult a doctor than to take supplements blindly. This won't necessarily help and could even delay addressing an underlying health issue. Finally, for those who compete, remember that you are responsible for what you consume. Some supplements are not subject to quality control (depending on their origin!) and could put you under scrutiny from anti-doping authorities! Opt for products displaying an NPN (Natural Product Number, which guarantees quality and quantity control of the ingredients).
As our dear Pierre-Yves McSween would say, "Do you really need it?" This applies perfectly to the use of vitamin supplements!
Have a good season!
