The Zipp 353 NSW was crafted with the endurance rider and road racer in mind while delivering speed and stability to tarmac, gravel, and everything in between.
Optimized for aero gains with a 30mm tire on the road and compatible with gravel tires up to 49mm, this multi-surface expert brings ceramic-bearing efficiency and Zipp’s advanced rim technology to the climb, the descent and everything in between. However, the 353 NSW does more than race; as Zipp’s first SRAM AXS-connected wheelset, it puts accurate tire pressure data right on your Hammerhead Karoo or bike computer of your choice.
The 353 NSW rim seamlessly integrates the Zipp AXS Wheel Sensor, letting you monitor and analyze tire pressure in real time without an external device mounted to the valve stem. Check your pressure before you ride – a green light means good to go – then keep an eye on it during the ride to dial in your ideal setting and detect issues early. Fine-tuning pressure helps you optimize speed and performance as conditions change.
Its undulating 35/40mm deep rim shape and 25mm internal rim width delivers low rolling resistance, crosswind stability and feather-light weight across any surface. At the center, our premium ZR1 SL hubset pairs ceramic bearings with 66 points of engagement for smooth rolling efficiency, saving watts on road or off.
The result is a wheelset that delivers everything the modern rider seeks – speed, strength, and versatility for road and gravel racing.
303 SW – Revised for Gravel Compatibility
The Zipp 303 SW is crafted with the multi-surface rider in mind – bringing Zipp’s legacy of innovation to road, gravel, cobbles and cyclocross in one modern classic. However, the 303 SW does more than go anywhere; with tire compatibility to tires up to 55mm, it opens up even more terrain, and its rim internally integrates the Zipp AXS Wheel Sensor for accurate on-bike tire-pressure monitoring.
Taking design cues from the gravel-specific 303 XPLR, the 303 SW’s 40mm deep rim uses a wide design for high aero efficiency and low rolling resistance on a wide tire platform built 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.
A revised carbon layup and design give the already bombproof 303 SW almost 10 percent better impact strength at a light weight, and its refined rim shape helps shield the tire in an impact that would otherwise cause a pinch flat. At the center, the ZR1 hubset now features stainless steel bearings for improved durability and smoother performance.
The result is a wheelset optimized for 30 to 35mm tires and compatible with tires up to 55mm, built for whatever surface the ride throws at you.
