XM 421 A 25 mm welded rim built for the demands of AM riding. A lightweight rim as wide as a downhill rim? What wasn't possible two years ago is today, thanks to cutting-edge materials and exhaustive testing. DT Swiss knows exactly how much weight to shave from a product so that it does its job perfectly. As light as an All Mountain rim can be, the XM 421 can handle any terrain, no matter how big the rock field it crosses.
