    These wheels ride like the ultimate gravel wheel. The 38mm deep carbon rim rides like a dream when paired up with a 42m tire. So even when you hit the pavement, they roll super fast. These wheels seem to pick up speed when they hit gravel roads and at the same time absorb a large amount of vibrations from rough roads.

    About 1500 miles into my Gulo experience and I’ve been shocked from the very beginning at just how good these are! In a back to back comparison with my trusty rusty ENVE SES AR’s they made the ENVE’s feel like a pool noodle. 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. I’m running them paired with 38c tires and the wide rim creates a perfect aero profile that most can’t achieve with a gravel setup. I’m completely sold on the woven carbon spoke technology and it’s obvious they’ve put in a ton of R&D. I don’t think I could go back after having ridden these!

    These wheels are the future of gravel racing. Ultralight, aerodynamic, and can take a beating! Love how wide the rims are, so they can fit a fatter tire like a 45! Great wheels all around and the new oil slick hubs are bling!!
