ZIPP 202 Firecrest Carbon 24H road rear wheel

The Zipp 202 Firecrest Carbon Clincher Disc-brake wheelset is all about new technology and new adventure. And a new era for road bikes. This trend-defining wheelset is now improved with the durable and versatile 77/177D hubset. That innovation means the 202 Firecrest Carbon Clincher Disc-brake wheelset is now thru-axle compatible. The 77/177D hubset combines with Zipp?s Firecrest technology to offer everything you look for in a disc-brake road wheel. The Zipp 202 Firecrest Carbon Clincher Disc-brake delivers the enhanced modulation and stopping power of disc-braking, whether you stay on the road or venture into less tame territory. At 32mm deep utilizing Zipp?s revolutionary Firecrest design, this wheel has the aerodynamic resume of wheels twice its depth yet handles more predictably than a shallow box-section wheel. To exceed 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. The 202 Firecrest Carbon Clincher Disc-brake wheelset comes with a standard 10/11 speed driver body for SRAM®/Shimano® or for Campagnolo®, allowing you to run a wide range of cassettes. For those looking for a wider gear range, or tackling especially extreme terrain, a SRAM XD driver body for 177D (sold separately) is easily installed to allow for more cassette options. A 1.85mm spacer is included with the XD driver body and is required for use on the 177D hub. XD driver body compatible with 11-speed cassettes only. The 77/177D hubset is surrounding by two most profound wheel innovations -- the Firecrest rim shape and Carbon Clincher technology. Firecrest rims have a near-constant width from brake track to spoke bed to improve aerodynamics and better control airflow. We used Computational Fluid Dynamics software analysis to maximize aerodynamics and minimize wind-produced torque, resulting in a 202 Firecrest Carbon Clincher Disc-brake wheelset that is faster and better handling than a classic road wheel. Our Firecrest rim shape improves stability by moving the wheel?s center of pressure to sit almost directly over the steering axis, where wind-produced steering torque has a minimal effect.
