Competition Wheels The XMC 1501 is one of the best wheels for mountain bikers today. Its light weight and strong specs help cyclist pedal to the maximum on every tight corner and jump on the track. The low weight of the especially for all mountain usage engineered rim paired with the latest evolution of our 240 hub with RATCHET EXP freehub make the XMC 1501 SPLINE ONE the perfect partner in crime for all different kind of mountain adventures. Due to the 30 mm inner width of the tubeless optimized carbon rim, wide tyres are ideally supported. Double butted competition race spokes and the perfect DT Swiss build quality are rounding the XMC 1501 SPLINE ONE off.
