The XMC 1200 SPLINE 30 is the ultimate all mountain wheel. A carbon layup specifically tuned for all mountain use makes the rim tough yet super-light. And with a 30 mm internal width, it is made for wide rubber. The hubs feature the latest incarnation of our Ratchet System. Extremely refined machining and fully lasered graphics make them the lightest hubs DT Swiss has ever made. Together with bladed top-end spokes and perfect DT Swiss build quality, this wheelset is made to ride trails with speed and confidence.
