Nox Composites Kitsuma 650B / 27.5" Carbon Tubeless Mountain Rim
Super wide and super sexy. There are times in life when you just don't care about light weight, pansy mountain bike rims. Like when you're staring down a fall line, psyching yourself up for riding at your limit. These are the times when a rim like the Kitsuma belongs on your bike.
Time and time again, the benefits of a wide rim have been shown. Nox has been hesitant to go this wide for a long time, since the selection of tires that work well for a rim like this were lacking, but times are changing and tires are now available which take full advantage of a beast of a rim like this. When you put on properly sized 2.35-3.0" tires on this rim, get ready to experience grip and lateral holding forces like you didn't think were possible on a mountain bike. The combination of stiffness, stability, compliance, low rolling resistance and raw grip are game changing. Note: If you are planning to run 2.1-2.3" XC tires, you will be better served with one of Nox's narrower rims.
The Kitsuma gets all of Nox's latest technology, including UniWeave construction, the Anti-Burp Bump, the strongest RockGuard Hookless bead lip they've ever made and of course their asymmetric offset design which improves spoke tension equality by more than 15%. The DH version of this rim shares the same profile but adds about 50g of material to add stiffness and structural integrity for DH style riding.
