From Nox Composites:
The 650b trend is no longer confined to trail/endure long travel bikes. More and more riders are moving to this wheelsize for pure XC riding and racing, and that's what this rim is designed for. Internally called the "no holds barred" rim, this rim is the result of almost a year of R&D efforts to push the limits of weight, stiffness and durability available in a carbon rim. What our engineers came up with delivers an abundance of lateral stiffness, our trademarked asymmetric design, a generous 23mm inner width and a continued refinement of our Rockguard Hookless bead designed to provide best in the industry durability to rock strikes or other direct rim impacts. In short, if you are looking for speed on a 650b, this is the best upgrade you can make for your bike.
Choose either White Industries CLD or XMR hubs. All mountain bike wheels will come with the new 48 point high-engagement ratchet ring installed.
Standard build configuration will be a mix of black Sapim CX Ray and CX Sprint spokes with Secure Lock brass nipples.
Please indicate desired hub and decal colour in the comments section of the cart. Also, please let me know what axle configuration is needed. Wheels are built to order and may take up to 4 weeks for completion depending on component availability.
