Gravel & Road Crossover



Full carbon gravel “crossover” wheelset with carbon composite G-Spokes built specifically to be lightest in class for both gravel and road biking.



With the GGX SL there are no limits to where you can go. Designed with gravel racing because of its incredible ride feel and lightweight, but also perfectly versatile for any surface you ride on.

Our super-light hooked rim was designed with a 2mm spoke hole offset for maximum strength. Spoke hole angles were optimized to create one of the most compliant and stiffest gravel wheels ever produced.

    These are the lightest, snappiest, comfortable and most durable wheels I have ever ridden. They’re so light and responsive, that the ride you get is unlike any other wheel out there. A big highlight on top it all, is the comfort. I feel with the carbon spokes, you’re getting a more comfortable ride without sacrificing performance.

  2. Nina Machnowski

    The GGX-SLs may be lightweight and one of the stiffest wheels on the market, but it takes some finesse for a rim to not only handle, but feel comfortable on all-day rides on Pisgah and DuPont gravel – and these wheels do just that!

  3. Carl Corley

    These wheels are insanely stiff, light, and comfortable. The carbon spokes eat up bumps & vibrations on the road unlike anything I’ve ever ridden before, which is ideal for those long gravel rides that would normally beat you up after a few hours. These have definitely been the best upgrade I’ve made to my gravel setup and I would highly recommend them!

    I received the GGX-SL’s to take them out and punish them on the Pisgah gravel hoping they wouldn’t punish me. And they fit the bill, they were stiff and responsive during acceleration and climbing and soaked up the bumps on the descents. Plus, they are absolutely beautiful and weighed in as advertised. Highly recommended!

    I waited a bit before writing a review so that I had time to put these wheels through the wringer. I’ve rode these wheels hard on many miles of gnarly gravel by now and they have held up to the abuse while maintaining a high performance feel. I’ve knocked rim at high speed and they are still trued and blemish free. These wheels are fast and they like the rough stuff. I highly recommend for gravel riding and/or racing!
