Our GMX 25 wheels are designed to devour the competition.  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.

“They perform as advertised and are one of the lightest and stiffest wheelsets one could buy and, the ride quality is top-notch.”
