Stan's NoTubes Arch CB7 27.5" (650B) Boost 15x110/12x148mm Shimano Wheelset

Stan's Ultimate Carbon Trail Rim
Stan's have created the Arch CB7 to be that ultimate carbon trail rim. It's wide enough to offer tyre stability and control, but narrow enough that your 2.35" tyres still corner great. It's light enough to respond instantly from the first pedal stroke but built with the kind of durability only developed on the Enduro World Series circuit. And when it comes to tubeless set up, it offers the easiest and most trusted system ever made. Five years of continual development and refinement have led to the Arch CB7's RiACT radial impact absorbing technology. The special layup and shape of the Arch CB7 deflects up to 10mm radially to soak up speed-robbing impacts, all while being laterally stiffer. The result is a rim that defies pinch flats and rolls faster over every trail. Arch CB7 rims also feature Stans patented Bead Socket Technology, the original tubeless-ready rim design that, combined with their sealant, has become the foundation of all current tubeless-ready systems. The Arch CB7 wheelset rolls on updated Neo hubs featuring a Durasync 6-pawl freehub with fast 10-degree engagement, and triple freehub bearings to better distribute axle load. The 100% CNC machined hub shell and smoother-rolling centreless ground axle help ensure long life and reliable performance. Sapims Race double-butted spokes are both strong and light. Combined with mechanically locking Sure Lock nipples, these spokes enabled a wheel build thats both lightweight and extremely durable.
