Wide is fast. Deep is faster. Our new GR50X rim gives you the best of all worlds. Deep (50mm), wide enough to support modern wide gravel (37mm OD, 29mm ID) tires while maintaining superior aero profile, and light! How light? While rim weights vary by ±5%, these come in at 415 grams.

Unlike the big brand option, if you use our gravel hubs (j-bend, 6-pawl, interchangeable endcaps) you also have the option to use Shimano Microspline freehubs!

Hookless bead rims with a classic aero profile. You cannot beat these for racing on gravel in the modern world. We can build you wheels or you can order the rims and have your local wheelbuilder create your dream ride. Contact us to explore wheel options!
