A-1 Aero.

Combined expertise in aerodynamics and Computational Fluid Dynamics paved the way for Profile Design’s first-class 38/TwentyFour Clincher Wheelset. To achieve the best rim profile for crosswind handling and reduced drag, Profile Design’s aero experts collaborated with a team of CFD technicians in designing, testing, and refining scores of rim prototypes. Ultimately the 38mm rim profile of the 38/TwentyFour distinguished itself as the winner; its subtle curve and rounded spoke-facing edge mitigates crosswind force while an external width of 24.5mm flattens the sidewalls, delivering impressive stability and smooth rolling.

The forged and machined 6061-T6 aluminum hub and shot-peened hard anodized 7001-T6 aluminum freehub deliver stiffness and an 18% increase in material strength, according to Profile Design, which translates to nimble shifting and greater power transfer that’ll give you a leg up in reaching your racing and riding goals.

For greater durability and braking performance, Profile Design developed a proprietary high Tg point resin for their TwentyFour series wheelsets that’s, according to PF, 30% higher than other “high” Tg resins.
