Smooth is fast. That's true even when the conditions and terrain get a bit chaotic... You know, cyclocross... gravel roads... steep lonely lanes... urban assaults. The Zipp 303 Firecrest Disc-Brake Tubular Bicycle Wheel is durable, lightweight and stiff while also providing the consistent and powerful performance of disc braking.
At the center of the 303 Firecrest Disc-Brake Tubular Bicycle Wheel is a newly designed 11-speed compatible hub. Larger Swiss stainless steel bearings with a custom cartridge in the rear hub shell provide increased durability. The hub geometry and virtual 3-cross spoke-lacing pattern are optimized for reliability as well as exceptional stiffness, resulting in efficient power transfer and quick acceleration. The result is superior performance in conditions ideal for disc-brake riding.
When it's time to scrub off speed or stop, you won't have to tense up and 'grab a handful.' You have the consistency and power of disc brakes - precision modulation and stopping power is at your fingertips. You also get the unmatched stability and aerodynamic efficiency of the pro-proven 45mm deep 303 Firecrest rim.
