Profile Design 78/Twenty Four Clincher

The draw: Course-specific technology

Having been out for a few years now, Profile Design continues to prove that it is a strong competitor in the wheel market with its Twenty Four series. Each wheel in the series is 24.4 mm wide, and the 78 model is 78mm deep. While the outside width is on par with other high-end carbon wheels, the internal width of the Twenty Four series is quite narrow (at 17mm). This helps combat heat buildup and allows for better, more predictable braking. Profile Design worked with course analyzing company SpeedTheory to take popular race courses into consideration when designing the wheels for real-world conditions.
