- Feature
- ific 303 XPLR to utilize a wide rim design for high aero efficiency and low rolling resistance on a wide tire platform designed for modern riding at lower tire pressures. The rim's profile provides low drag and an improved transition between rim and tire, boosting aerodynamic efficiency with wider tires.
- Feature
- The wide-rim stance also features less tire deflection for reduced rolling resistance. Combining the wider tire, increased tire volume, and lower tire pressure helps reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions—the tire and wheel system absorbs the shaking, not the rider.
- Feature
- A revised carbon layup and design also infused the already bombproof 303 SW with an almost 10 percent improvement in impact strength at a light weight.
- Feature
- The 303 SW is optimized for tires 30 to 35mm in width, with the best performance with 35mm tires. The 303 SW rims feature a refined shape that helps shield the tire in an impact that would otherwise cause a pinch flat.
