The GMX SL is our lightest and most advanced XC race wheelset, built for riders who refuse to trade durability and control for grams. Designed to be the ultimate all-around XC wheel, it delivers ultra-low weight with real-world strength, precise cornering support, and long-term reliability, so you can race hard without worrying about fragile components or constant truing.
At the heart of the GMX SL is our proprietary braided composite spoke. Compared to steel, it reduces vibration by approximately 8% while offering higher tensile strength and greater impact resistance. Unlike unidirectional carbon spokes, the braided construction absorbs impacts without being brittle, resulting in a smoother ride, that holds tension better — a true no-compromise XC race wheel.
Rider Weight Limit: 210lbs
If above 210lbs, we recommend the 100gram heavier GMT 30
Lifetime Warranty. 30-day money-back guarantee.
