In the case of the Aspero, aerodynamic performance isn't so much about pure speed resulting from reduced drag as it is about energy conservation. After a long day in the wind, the 3 watts saved compared to the old Aspero can mean one less energy gel for your stomach to digest, which is definitely worth it.

In addition to reducing drag, the seat stays have also been lowered to provide a bit more compliance at the rear and slightly reduce stiffness at the front, making the final hours of a long race less painful. Between these lowered seat stays, there's also a bit more room for mud, taking into account lessons learned from the R5-CX (and the 2023 Unbound Mud Festival). These are a multitude of seemingly minor improvements, but together they make a big difference. The result is a bike that feels very much like the original Áspero, but is faster, more comfortable, and more versatile.
