I purchased this wheel set as an upgrade from the stock wheels on my Canyon Roadlite CF bike. The ride is much improved, as the bike feels more like it should: a flat handlebar road bike.
These wheels can be run as tubeless, but I'm using them with inner tubes. The one thing I find a bit confusing is the 72 psi maximum inflation. I assume that applies if you're riding tubeless on gravel. I use this bike only on paved roads, and my Vittoria Zaffiro tires have a minimum psi of 87.
I bought the GRX wheels as a second set for my allroads bike on the recommendation of my independent mechanic. He claimed that these wheels rode as well, if not better, than wheels costing twice as much. He wasnt exaggerating. I mounted 28c Conti GP 4-Season tires (set at 80 psi) and the ride is incredible. With 1000 miles on and some big spring rides coming I could not be more pleased. Or, maybe I could. I am not running these wheels tubeless yet but plan to when I need new tires. Finally, I will add that I have a set of alloy wheels that did cost twice as much as the GRX set. I like the GRXs better.
This tubeless ready wheelset was exactly as described.
I bought these wheels two months ago on a recommendation from my go-to Velofix mechanic. He said these wheels performance is comparable to wheels that cost twice as much. IMO, that was an understatement. I put the wheels on my enduranceadventure bike. I am running Conti GP 4 season 28c tires. The wheel tire combination run at 80 psi spins up quickly and rolls smoothly. I highly recommend these wheels.
