At the forefront of Carbon rim innovations is the Bombshell CSO rim. The choice rim brand for racers from novice to elite worldwide, Bombshell is certainly a highly regarded name and the CSO rim does not disappoint. Featuring Torray 3 layer carbon these rims are ridiculously light, stiff and, most importantly, strong. Aspects of the CSO’s design have put an end to the issue of nipples pulling through the rim that you may find with some of the cheaper brands. The rear rim features a Basalt breaking surface, but we still recommend use of a carbon specific pad. Lightweight, Strong and Stiff. Torray 3 Layer Carbon. Front and Rear Specific.
