Real-Time Tyre Pressure Monitoring: Zipp Introduces Integrated Pressure Sensors in New Wheel Lineup
Zipp Unveils Four New AXS-Connected Wheelsets
Cycling equipment manufacturer Zipp has announced the release of four new wheelsets, each featuring an innovative tire pressure monitoring system integrated into the rims. The new wheelsets, named 353 NSW, 303 SW, 454 NSW, and 858 NSW, are part of Zipp's AXS ecosystem and permit seamless integration with SRAM's electromechanical groupsets and digital bike systems.
These wheelsets boast real-time tire pressure sensors built into the rims, which work alongside the SRAM AXS app for detailed telemetry and are compatible with Hammerhead, Wahoo, and Garmin head units. The integrated AXS Wheel Sensor indicates tire pressure levels via a green light for correct pressure and a red light for discrepancies.
The 353 NSW, Zipp's first AXS-connected wheel, delivers in-wheel tire pressure monitoring on the lightest rim design. Weighing approximately 1,310g, the revised carbon layup makes the wheel 16% stronger than its predecessor without adding excessive weight. The 303 SW, another model included in the new lineup, is designed as an all-terrain wheel, evolving from Zipp's gravel-oriented 303 XPLR.
Designed for tubeless setups, the system includes specially built 'smart tubes' with sensor-specific valves. These tubes, provided with the wheels, are intended for emergency situations when tubeless flats cannot be repaired. Fitted with ZR1 SL hubs and ceramic bearings, these wheels exhibit an impressive 30g weight reduction compared to previous models.
Zipp has also teamed up with Goodyear to produce two tires customized for the 303 SW XPLR wheel and the 454 NSW's new 23mm TSS rims. The 303 XPLR-specific Goodyear Vector R XPLR tire, featuring an undulating 40mm rim depth with a 25mm internal width, prioritizes aerodynamic efficiency and low rolling resistance for a smoother ride. The second tire, the 29mm Goodyear Eagle F1 R Z29 Aero, designed for wheels using Zipp's 23mm TSS rims, focuses on aerodynamic efficiency and low rolling resistance.
Below is a summary table of the key specifications for these new AXS-connected wheelsets:
| Wheelset | Rim Depth | Inner Rim Width | Tire Compatibility | Brake Type | Key Features ||-----------|------------|-----------------|--------------------|------------|-------------------------------------------------------|| 353 NSW | 40 mm | ~25 mm | Tubeless only | Disc | Lightweight climbing wheel, improved impact strength, AXS sensors, ceramic bearings || 303 SW | 40 mm | 25 mm | Tubeless only | Disc | Versatile and sturdy wheel, wider rim profile, AXS sensors, ceramic bearings || 454 NSW | ~58 mm | Similar (~25 mm)| Tubeless only | Disc | Deep rim wheel with aerodynamic focus, AXS sensors (inferred) || 858 NSW | ~80 mm | Similar (~25 mm)| Tubeless only | Disc | Time trial/triathlon aero wheel, deepest rim, AXS sensors (inferred) |
*Rim depths for 454 NSW and 858 NSW are based on typical Zipp model naming and previous product lines; exact 2025 specs were not fully detailed in search results.
