Zipp 404 Firecrest Carbon Clincher V3 Road Wheel - Front
The Firecrest Aero 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. Its 58mm rim profile with 26.53mm max rim width accounts for the differences in airflow patterns between clincher and tubular tires, far exceeding the aero performance of any other clincher wheel in its class. 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. Zipp's exclusive resin improves heat dissipation, and when combined with their Platinum Pro EVO brake pads, provides unmatched braking power, even on harrowing descents. Oversized Zipp 88 hub increases torsional rigidity by 28% for more direct power transfer, uses larger precision Swiss steel bearings for increased durability, and features adjustable preload to increase bearing life and ride quality. p>
The 77/177 hubset brings improved stiffness and durability over the hubset found on the previous generation of hubs, with wider flanges and a bigger axle. There's also no longer a need to set a bearing preload, and the bearings are also better protected from the elements, which means less wear and maintenance. A new improved quick release skewer also improves wheels retention and a more ergonomic lever for easier use.
