Enjoy flat-land speed and rocket up mountains, too, with Zipp’s 202 Firecrest Carbon Disc Brake wheels. Not only do these light wheels set a high climbing standard, they also excel over rough roads and handle like champs in stiff crosswinds. The slippery profiles of Zipp's 32mm-deep, 25.4mm-wide dimpled rims are more aerodynamic than even many deep-section wheels. Zipp's 77D/177D disc hubs give you incredible stopping power in wet and dry conditions alike, and they're thru-axle compatible (sold separately) for jaw-dropping steering precision and power transfer. Plus, they're super smooth thanks to precision bearings. And, the finishing touch is Sapim's outstanding CX-Ray spokes.
