XC Race



Go fast. Go fearless.

The cross-country race-day GMX-25 wheel system is all about speed and top-tier performance. With sharp acceleration and handling at its core, the GMX-25 is the lightest and fastest mountain bike wheel in the lineup. The combination of our composite spoke-and-hub system and highest quality matched rim has yielded our race-spec XC wheel. Possibly the lightest and stiffest mountain bike wheel ever produced. Designed to devour the competition.
