The Zipp 303 Firescrest Disc rim is stiff, lightweight, stable and aerodynamic, and paired with the Chris King R45 hub, it's a miracle to ride.
The ride is fast and sure-footed, balancing power transfer with vibration damping, to communicate confidence back the rider. When you're getting rowdy on rough terrain, confidence is key. The rim is wide, to optimize tire fit, and deeper to confer as much aerodynamic benefit as possible. In real world terms, that means it's slightly more bulbous in design than its predecessor, with a 30mm outside width, a 25mm internal width, and a 40mm rim depth. Did we say they were aerodynamically pleasing? They are.
Chris King R45 Centerlock™ hubs pair a lightweight hub body with their legendary, made-in-house bearings. They give you 45-points of simultaneous engagement, and that means more of your power gets to the ground and your traction is better. These hubs just roll better, last longer, and look way more handsome than anything else out there. The stiffness of our one-piece axle translates to laser-precise bike handling.
CK bearings, both steel and ceramic, have heat-treated, surgical grade steel races that are machined simultaneously to ensure perfect matching. The quality and speed of our bearings is what you will feel (and hear) on every ride. As Chris King bearing tracks burnish they get actually get faster. A little bit of regular love (i.e. service) will keep this hub rolling for years upon years of demanding use.
