Zipp 303 XPLR SW Carbon Tubeless Disc Brake 700c Wheel 12x142mm

The Zipp 303 XPLR SW wheelset represents our fastest gravel wheel to date, featuring an extra-wide and deep rim engineered to perfectly complement gravel tires. Unlike typical gravel wheels, which are adaptations of road wheels prioritizing stiffness and weight, Zipp’s design centers exclusively on maximizing speed. Recognizing that rolling resistance, vibration from uneven terrain, and wind significantly hinder gravel riding speed, Zipp applied its Total System Efficiency philosophy tailored to these challenges. The 303 XPLR SW is a purpose-built gravel wheel designed around the ideal gravel tire for optimal performance. 

To develop this first-of-its-kind wheelset, Zipp engineers learned from studying how gravel racing has changed cycling in recent years, coming to several vital conclusions:

1. The progression of gravel speeds increases the importance of aerodynamic efficiency.

2. Current generation gravel wheels exhibit poor aerodynamic efficiency with gravel tires.

3. Low tire pressures are the key for unlocking speed on gravel, but current gravel rim design provides insufficient tire stance to support lateral cornering loads at lower tire pressures.

4. Current gravel rim designs do not help prevent pinch flats while using lower tire pressures.

Gravel racing tires typically range from 38 to 50mm in width with diverse tread patterns, while most gravel wheels feature an external rim width of 28-30mm, causing aerodynamic inefficiency when paired with tires over 40mm. This mismatch creates a bulbous tire profile rather than a smooth airfoil shape. Zipp’s 303 XPLR SW wheelset, designed for optimal tire-wheel integration, delivers a 5-watt aerodynamic gain compared to top competitors. Engineered for use with Goodyear XPLR Slick and Inter tires, it supports lower tire pressures by widening the tire bed, enhancing cornering stability and traction while reducing vibration. The rim edge is 77% thicker than previous models, minimizing pinch flats. At 54mm deep, the rim balances aerodynamic performance and stability at race speeds exceeding 35kph, perfectly matching the profile of a 40mm gravel tire.
