Zipp 404 Koło klinowe Tubeless Shimano 10/11/12-rz.

The Zipp 404 wheelset with tubeless tyres is a very high-end model for performance-oriented competitors with great versatility. Combining the incredible efficiency of carbon and Firecrest technology (specific toroidal profile), this 58mm high wheelset is light, stiff and aerodynamic, making it equally at home in the mountains, on the flat or in sprints, making it the ultimate weapon for competitions on varied profiles.

A tubeless configuration allows you to reduce tyre pressure for greater comfort while reducing the risk of punctures during your ride. You can save crucial seconds thanks to the increased grip in corners and lower rolling resistance. With no inner tube interacting with the tyre, this system causes less friction, which reduces rolling resistance. This version is offered with the new 77/177D hubs offering improved lateral and torsional stiffness and reduced weight, thanks to optimised flanges and Sapim CX Sprint opposed spoke spoking. In addition, Zipp has removed the bearing preload adjustment nuts, which required frequent adjustment. With more ergonomic quick releases, these wheels are also equipped with adapters that can be mounted without tools, making them compatible with 15x100 mm and 12x100 mm axles at the front and 12x142 mm and 12x135 mm axles at the rear.
