Reserve 30|XC are modern race-ready wheels, built for big efforts and the demands of modern XC bikes. The wider rim width provides additional tire sidewall support and increased grip. Additional spokes create a stronger, stiffer wheel compared to 24-spoke wheels. 30|XC is built for speed. They'll help push your rivals and your riding buddies to their limit, every lap. We offer the new 30|XC Wheels with our SL rims, Vonoa carbon spokes and DT 180 hubs. This package offers ultimate precision and unparalleled power transfer. For race only. Or not.
