In cycling, we celebrate marginal gains—yet often overlook one of the most consequential variables: tire pressure. It affects everything from rolling resistance and grip to fatigue and flats. SRAM has now brought this fundamental metric into the digital age with its new AXS Tire Pressure Monitoring System, exclusively available on two elite Zipp wheelsets: the 303 SW and 353 NSW.

These are not retrofits. These are precision-engineered, fully integrated systems that elevate performance through data.

With SRAM's new AXS Tire Pressure Monitoring, you get real-time data from inside your tire, displayed right alongside your watts and speed. It gives you:

• Live pressure and temperature readings
• Instant leak or puncture alerts
• Ride-by-ride data history
• Seamless integration with the AXS ecosystem

This isn't tech for tech's sake. It's about confidence. It's about tuning your setup to perfection every time you ride.

Zipp 303 SW: Precision in the Real World

Key Specs

• Rim Depth: 40mm - versatile for climbing, aero on the flats
• Internal Width: 25mm - optimized for 28-32mm tires
• Weight: ~1,355g for the set
• Hub: ZR1 DB with AXS Tire Pressure Monitoring System integrated
• Freehub: XDR
• Tire Interface: Hookless, Tubeless-only

Performance Advantages

• The 25mm internal width allows lower pressures with wider tires, reducing rolling resistance and increasing comfort.
• At 40mm, the rim hits the sweet spot between climbing agility and aero performance—ideal for varied terrain.
• ZR1 DB hub offers fast engagement and sealed cartridge bearings for lasting performance.
• With tire data in real time, you can ride that fine line between low-pressure grip and pinch-flat risk with total confidence.

Whether you're conquering tarmac in Tuscany or carving switchbacks in Colorado, the 303 SW is a game-changer for riders who demand everything from a single wheelset.

Zipp 353 NSW: The Pinnacle of Performance + Intelligence

If the 303 SW is the high-performance workhorse, the 353 NSW is the thoroughbred. This is Zipp's most advanced road wheel, built for the rider who wants no compromises.

Key Specs

• Rim Depth: Varies (45mm max) with Zipp's patented Sawtooth™ undulating profile
• Internal Width: 25mm
• Weight: ~1,255g for the set
• Hub: Cognition V2 Hubset with Axial Clutch™ technology
• Tire Interface: Hookless, Tubeless-only
• Tire Pressure Monitoring: Fully integrated with AXS system

Why It Matters

• Sawtooth™ Rim Design: Enhances crosswind stability while reducing aero drag—ideal for real-world riding where wind is never head-on.
• Cognition V2 Hub: One of the smoothest, most efficient hubs on the market, with Axial Clutch engagement for quicker response and less drag.
• Featherweight Carbon: At just over 1,250g, it's among the lightest wheelsets that can still handle rough roads and aggressive riding.

With AXS Tire Pressure Monitoring built in, you now have full visibility into your most critical contact point with the road. No more guessing. No more over-inflation. No more flats from missing a slow leak mid-ride.

AXS Tire Monitoring + Zipp = The Ultimate System

SRAM didn't just make a tire sensor. They made a system.

By embedding real-time pressure data into the heart of their Zipp wheels, and connecting it via AXS, they've created a closed-loop performance platform that's unlike anything else in cycling. It's not just about collecting data—it's about unlocking precision tuning before, during, and after every ride.

Whether you're racing, exploring, or just chasing your best self, the 303 SW and 353 NSW give you a smarter wheel with an uncompromising edge.
