Zipp rear wheel - 404 Firecrest Carbon Tubeless Disc Brake Centre-Locking 700c Rear 24-Spokes XDR 12x142mm Standard Graphic B1

Adaptable in the face of ever-changing road conditions, the Zipp 404 Firecrest XDR™ 12x142mm Rear Wheel is engineered for achieving speed and efficiency. With a rim depth of 58mm, this wheel is great for road racing, triathlons and riding over various terrains, and its internal rim width of 23mm means you can ride with wider tyres at lower pressure, increasing performance and riding quality. Thanks to SawTooth™ technology, the wheel adopts a dimpling pattern that vastly increases its aerodynamic efficiency, also increased by hookless rims that improve the transition between rim and tyre, reducing drag. The SRAM XDR™ driver body allows for lighter and more versatile drivetrains, keeping the weight of your bike down and offering better axle and bearing durability.  Engineered in Germany, the new ZR1 disc brake hub has been developed to improve durability and a quicker response time, so the bike abides to your every movement.
