Designed to be the lightest and smoothest possible. This low-profile carbon rim is only 1281g /set, giving you performance benefits like superior climbing and supreme vibration reduction thanks to the G-Spokes w/ Ride Smooth Technology. The nimbleness of this wheelset can be felt as soon as your first pedal strokes, where these wheels seem to almost accelerate on their own. Reducing vibrations is a key feature because, as the lightest and smoothest road/gravel wheel on the market, those benefits are compounded because they can help you ride longer and farther with more comfort. Long mountain rides have never been as comfortable as they are with the GGX SL.

This wheelset spans categories. Road, gravel, and cyclocross in one. The internal rim width is 22mm, wide enough for wider tires, and the rim has a hooked rim bead, safe for high-pressure road tires. The recommended tire size is 25C-48C. 

Lifetime Warranty on Gulo G-Spokes and a 30-day Money-back Guarantee make trying these wheels worry-free.

Hand-built in Brevard, NC.

5 reviews for GGX-SL

  1. Reny Townsend (verified owner)

    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!

  2. Charles Miller (verified owner)

    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!

  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!

  4. 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!

  5. Ally Murphy

    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.
