Product Description
Beginning with the rims, Proven Carbon Race XC UD follow the principles of the rest of the Proven family, offering tuned compliance and stability with a modern 30mm internal width, but with the goal of making a competitive XC race wheel, low weight. Using carbon UD spokes which can withstand a maximum tensile load of 405 Kgf, Proven Carbon Race XC UD is our lightest mountain bike wheelset to date and features our free H_Care lifetime crash replacement warranty.
Design changes like a reduction to a 22mm rim height and 36mm external rim width naturally reduce materials and weight, but our engineers didn’t stop here. Through the testing and study of carbon processes, resin choices and construction methods, we have been able to shave off every unnecessary gram while reinforcing key structural areas. The result is a front rim weight of 348g and a rear of 369g.
The search for speed didn't just stop at low weight. Our engineers also heavily invested in increasing efficiency by utilising super smooth EZO bearings throughout and updating our ratchet system to the latest S_RapidEngage system featuring a 3x2 pawl design and increased 90T ratchet for an incredible 2-degree engagement angle for instant power transfer from the pedal to the trail.
Our lightest XC race wheel
Engineered in West Sussex, UK and raced throughout the 2022 UCI XC World Cup season, Proven Carbon Race XC UD wheelsets weigh in at an unrivalled 1254g.
