- 45mm ultra-light carbon fiber rim
- Firecrest shaping improves stability in crosswinds and aerodynamics
- 77/177D hubset is stiffer and more rigid
- 6-bolt disc and thru-axle compatible
Details: The next evolution of the Zipp Firecrest is upon us, with the introduction of disc-ready wheels. These adventure ready wheels combines the groundbreaking Firecrest rim shape for unstoppable performance with the new and improved durable and versatile 77/177D hubset with thru-axle compatibility for a wheelset that's ready for a new era of all-road riding.
The Zipp 303 was the first carbon wheel to win cycling's two most famous Cobbled Classics, Paris-Roubaix and the Tour of Flanders. Now, it's been completely redesigned with Firecrest shaping and a 28.5mm max rim width for extra durability and improved aerodynamics in unforgiving conditions. The Firecrest rim shape improves stability by moving the wheel's center of pressure to sit almost directly over the steering axis, where wind-induced steering torque has a minimal effect. As a result, its 45mm rim profile combines the wind-cheating advantage you'd expect with the crosswind stability of a box-section rim. The Firecrest platform also increases lateral stiffness for sprinting and cornering, while offering greater vertical compliance for more control, comfort and durability on rough surfaces.p>
The 77/177D hubset brings a stiff, thru-axle compatible hubset than found on the previous generation of hubs, with wider flanges and a bigger axle. 6-bolt disc rotor compatibility means that the 303, already renowned as an excellent all-around performer, now also delivers the improved modulation and all-weather stopping power of discs, the 303 becomes a fully functional adventure wheel that's ready for cyclocross, gravel, or simply exploring the road less traveled.
To live up to the demands of gravel and adventure road riding, the 202 Firecrest Carbon Clincher Disc-brake wheelset also is laced using Sapim brass nipples for increased stiffness and durability in all conditions.
