KinLin's XC-279 rim is a wider version of their XR-270 with a rounder cross section. The width has been increased 4mm, from 19mm to 23mm at the brake track. The profile is rounded at the nipples making it more comparable in shape to HED's Belgium C2 rim. The profile is 1 mm taller as well. The rim is, like all KinLin rims, extruded from a superlight Niobium-Aluminum alloy and joined with a high quality sleeved joint. Finish work on these rims includes glossy anodization and machined sidewalls.
