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 wheelset is durable, lightweight and stiff while also providing the consistent and powerful performance of disc braking.
At the center of the 303 Firecrest Disc Tubular Disc-brake wheelset 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.
It all adds up to a smooth ride. And as cyclocross and road veteran Tim Johnson likes to say, smooth is fast. “In dry conditions the one-finger braking can mean the difference between stuffing it up in the corner by sliding out, or keeping on the edge of the perfect racing line,” said Johnson, of the Cannondale p/b CyclocrossWorld.com Team. “In muddy and sketchy conditions, consistent braking, or having brakes at all help me stay in the right rut or give me the confidence to let it rip and push even harder than the previous lap.”
In other words, control over chaos.
