I recently purchased these and even though they came with 40mm Yksion Allroad tires installed I wanted to test out Mavic's UST tubeless. I removed one tire completely and reinstalled it. Seated within seconds using a simple floor pump. As soon as pressure got near 20 psi the tire popped into the beads. Easy as that. I deflated, added sealant, reinflated and it held air perfectly. Hubs are smooth, build quality seems strong, and although not the lightest wheels out there I dropped a full pound and a half off my gravel bike by replacing wheels, cassette and rotors.
Bought in to the road tubeless craze and after seeing a few videos, including one from GCN, decided to go with this wheelset. Haven't regretted it yet. Wheels and tires have been durable around Michigan's terrible roads, crashing through miles of broken asphalt and concrete, gliding along debris-covered shoulders, and shrugging off anything and everything in its path. The tires roll and grip very well at 80 psi, haven't assessed wet weather grip yet. Hubs engages very quickly and has a quiet but nice-sounding freewheel noise. Wheelset looks great with the aero spokes. Tires went on very easy, especially compared with my OE wheelset, where I removed some skin and blistered my hands trying to put tires on the OE rims. Very satisfied after 500 km of use so far.
Being 6ft-4in tall and having a 200-pound rider weight, I have a history of performance issues with several name brand wheels. So far, I have only good things to say about these wheels.
I rode the Ronde PDX Within the first 200 miles of ownership. These wheels silently climbed the steepest grades and handled beautifully while mounted to my Niner RLT. I experienced no spoke pinging or flexing creaks. Now after several hundred miles, the wheels are still true and are working perfectly. This set of wheels, with their 24 spoke count and wider rims, have exceeded my expectations. They are well assembled using quality parts. My set came with a signed certificate showing who hand built the wheels at the Eugene, Oregon factory.
I use this wheel for my everyday riding. I use it to do training on the hills. It climbs like nothing would stop it. It responses quickly. the width of the rims help you descentconering with super confident. Just point and go.
