Zipp’s super-fast 404 Firecrest Carbon Clinchers set a new benchmark for deeper-section aerodynamic control and speed.
The unique 58mm, cigar-shaped profile centralises the aerodynamic balance of the wheel for superbly surefooted cornering and much less gusty and more controllable handling than on most shallower rims in high winds.
Despite an extremely low weight making acceleration and climbing a breeze, the wheels hold their speed very well in mixed wind conditions. The big hollow rim and broader tyre bed give superb feedback clarity while muting the worst rough sections.
New hub engagement is among the fastest on test, and braking is also confident and predictable.
