Design evolution

The 303 SW’s 40mm deep rim design takes design cues from the gravel-specific 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.

Refined capability

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. The 303 SW is optimized for tires 30 to 35mm in width. The 303 SW rims feature a refined shape that helps shield the tire in an impact that would otherwise cause a pinch flat. At the center of this is the ZR1 hubset, which now has stainless steel bearings for improved durability and smoother performance.
