XM 421 A 25 mm welded rim designed to meet All Mountain (AM) requirements. A lightweight rim as wide as a downhill rim? What wasn’t possible two years ago is now a reality thanks to cutting-edge materials and exhaustive testing. DT Swiss knows exactly how to balance a product’s weight so that it performs perfectly. As light as an All Mountain rim can be, the XM 421 can handle any terrain, no matter how rocky the path may be.
