  • DT Swiss XM 421 25mm Mountain Bike Rim

    The XM 421 25mm MTB Rim from DT Swiss is a lightweight and tough all-mountain (AM) rim and its internal width of 25mm makes it perfect for today’s trend toward wider tyres. Constructed using high-end materials and precise machining, DT Swiss has removed excess material from unnecessary areas, creating a very light rim without sacrificing structural strength. Although it's light, it can handle anything the trail can throw at it and will keep on rolling regardless of how many times you tackle rock gardens, ruts and off-camber high-speed descents.
