GGA 38s are our rip-roaring aero wheels. Gravel riding is entering a new era, with speed and aerodynamics becoming synonymous with gravel riding and racing.

[smartslider3 slider=”6″] In a long gravel race, there are plenty of things that can make your day go one way   or another, and Gulo’s AllTerra GGA 38 gravel wheel is the obvious choice when you’re looking to stack the odds in your favor. The Gulo Integrated System brings it all together. Lightweight and durable are givens. Add in incredible compliance to stave off the fatigue that a long day in the saddle brings, plus the incredible aerodynamics of the 38mm deep sectional rim, and you’ve come prepared to ride at full tilt.
Brian G.

I have to admit I was skeptical that a wheel set could exist that checks the amount of boxes that my GGA38’s do but I was shocked from the very beginning just how good these are!The Gulo’s are noticeably stiffer/more stable in the lateral and longitudinal planes – especially when out of the saddle climbing or under hard braking – yet somehow also the smoothest and most comfortable wheels i’ve ever ridden. They seem to magically iron out every ounce of chatter on the road. “
