The XR 1501 SPLINE ONE wheels are built with the performance and budget conscience cross country rider in mind. Featuring aesthetic but tough, XC use-specific aluminum rims, they give you snappy accelerations without the hefty price tag of carbon wheel options. Rolling on ultralight and race-proven Ratchet System hubs every bit of your energy is transferred into forwarding motion via equally racy double butted spokes and a perfect wheel build.
