I took a leap of faith and ordered these for my 2015 Jet 9 Carbon. The set cost me ~$400 shipped with Powerway M32 hubs. The wheels shipped quickly (next day) and arrived super fast (within 8 days of order). They setup tubeless in less than 30 minutes with Stan's rim tape and sealant, Maxxis Ardent 2.25 in the rear, High Roller II 2.3 in the front. Now to my riding impressions.
These wheels are SUPER stiff, super light and very durable. I've thrown them onto the truing stand every two weeks for the past 2 months and no issues with spoke elongation or nipple settling. I crushed all my times up and down just about everywhere I ride, but I had to reduce my fork and shock pressure because the stiffness made the ride so harsh. I also tried reducing the tire pressure and this worked.. to a point.. which is my next point.
The rim bead cracked mid-ride when I hit a sharp rock in the middle of the trail, which means I was probably running them too low. I had never bottomed out at any pressure with these before, and the rock garden I was traversing I had been through many times, so I guess I was just unlucky this time. I immediately emailed customer support and sent them pictures of the impact, and they shipped me a brand new rim the next day! Their only advice: "This wheel is super light XC wheels, so please do not use them on poor road conditions. thanks for your support."
I bought these for mountain biking, and the mountains around here are a little bit rocky.. did I miss something when I bought these? I don't think so, because they have been bombproof until I was an idiot and ran them too low. I would rate these an A+ for the price and customer service and recommend them to anybody looking for a great set of wheels at a great price.
The only caveat, as with any carbon rim, don't run <20psi. Also make sure you don't over-torque the cassette into place if you run an XD driver, the endcaps protrude a lot and the freewheel tool does not make adequate overlap with the splines enough and you will strip them out, thus requiring a new cassette.
