ZIPP 303 SW CARBON TUBELESS DISC BRAKE CENTER LOCKING 700C FRONT 20SPOKES
12X100MM STANDARD GRAPHIC A1 - WHEELThe 303 SW rim internally integrates the Zipp AXS Wheel Sensor for accurate
on-bike tire-pressure monitoring. It allows you to monitor and analyze tire pressure
in real-time without an external device mounted to the valve stem. Fine-tuning tire
pressure helps riders optimize speed and performance in an ever-changing riding
environment. Before you ride, check your pressure immediately; green light means
good to go. During the ride, monitor pressure to dial in your ideal setting and detect
issues early. 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.
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. 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.
