Five years of continual development and refinement have led to the Arch CB7's RiACT radial impact absorbing technology. Unlike lesser carbon rims that ride stiff and transfer impacts and vibration to the suspension and rider, 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 than just about every other carbon and alloy rim on the planet. The result is a rim that defies pinch flats and rolls faster over every trail.
