The 303 brings a lot to the table, including heritage proven in the world's hardest races. At the center of the wheelset is Zipp's 77/177 hubset, which results in improved stiffness, durability, simplicity and versatility. The carbon wheel that helped pioneer the Firecrest rim platform for improved aerodynamics and crosswind stability also features the unspoken durability that has repeatedly won Paris Roubaix and the Tour of Flanders - Firecrest rim technology affords the rider more speed, more stability, and more strength. This technology offers stable, predictable handling, and the wider rim increases lateral stiffness while offering greater vertical compliance. Each Wheel Includes: - Zipp Tangente Quick Release Skewer - Zipp Tubeless valve – factory installed - Tubeless rim tape – factory installed - Valve core removal tool - Zipp 77D/177D thru-axle caps to fit 12x100, 15x100 and 12x142 dropouts

Road bikes are going where they’ve never gone before, are expected to do more, and are being ridden harder than ever. At the same time disc brakes are rewriting the rules of what’s possible with rim design. For this new era, the Zipp 303 Firecrest Tubeless Disc-brake wheelset sets the new standard. With a disc-specific, tubeless rim, the 303 Firecrest Carbon Clincher is now internally 21mm wide and faster than ever. Designed from the start as a tubeless rim, the 303 Firecrest features a rim bed made with internal ridges to lock the tire’s bead in place, ensuring secure performance, even when ridden at lower tire pressures. A new carbon fiber layup keeps weight low while maintaining the 303’s legendary durability. The rim’s lightweight design allows the 303 to glide up the steepest climbs while SRAM's robust 77/177D hubset keep the wheels stiff and responsive. Each Wheel Includes: - Zipp Tubeless valve extender and valve-core wrench - Zipp rim tape (factory taped) - Zipp Tangente quick-release skewer - Zipp thru-axle end caps

Zipp's 3ZERO MOTO carbon enduro/trail wheels are inspired by moto to provide riders with the control and durability required for pure speed. Moto remains a powerful source of inspiration for good reason. Based in the racing hotbed of Indy, Zipp for more than three decades has used motorsports as an inspiration to develop pioneering carbon cycling innovations. Our single-wall approach, what we call Moto Technology, allows the rims to "pivot" from either side of the spoke bed while traversing rough terrain. As the wheel encounters obstacles, each edge of the rim is designed for compliance, creating the feel of extra suspension. For the rider, that means durability and control for greater speed. Moto Inspired. Control + Durability = Speed. - Higher impact resistance - Reduced chance of pinch flatting - More traction in rough corners - More traction in rough corners - Smoother ride in rocky terrain - Ability to run lower tire pressure - Reduced rider fatigue - TyreWiz tire-pressure monitoring device - Frustration-free tire installation - Rim is designed for compliance, creating the feel of extra suspension
