I got these wheels for the weight savings and compliance everyone talked about as I prepared for the Leadville Trail 100 and Little Sugar MTB races. The weight savings, even over top end wheels from a few years ago, is significant and, while it is harder to quantify, my experience has been that the additional vibration damping over a long ride is just as valuable. I'm very happy with these and would recommend highly if you're shopping in this price range.
Unbelievably light!!
A sturdy, dependable, quick, lightweight addition to my lightweight xc build
First ride today, these wheels are awesome, TY
The best xc mtb wheels money can buy!
