With an all-new disc-specific, tubeless rim, the 303 Firecrest Carbon Clincher is now internally 21mm wide and faster than ever.
The 45mm deep 303 Firecrest delivers unmatched aero performance when used with the wide tires that today’s riding demands. We’ve achieved this with a wide disc-specific rim design featuring ABLC™ dimples extending all the way to the outer edge of the rim. In addition to achieving AeroBalance™, the industry leading crosswind stability and low aerodynamic drag that defines all Firecrest wheels, the new 303 Firecrest delivers lower drag than the outgoing version when used with 25c or wider tires. The aerodynamic performance gap between a narrower rim and the new 303 grows even larger with 28c and wider tires thanks to a smoother transition between the tire’s profile and our new rim shape.
