DT Swiss XM 421 25mm MTB RimThe XM 421 25mm MTB Rim from DT Swiss is a lightweight and sturdy All Mountain intended rim, which has similar dimensions to a Downhill rim a few years ago. Constructed using high-end materials and precise machining, DT Swiss was able to remove material in unnecessary areas, creating a very light rim without sacrificing structural strength. Although it is 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.Features: Material: Aluminium Internal Rim Width: 25mm Outer Rim Width: 30mm Brake Compatibility: Disc Brake Use: All Mountain Type: Tubeless Ready Weight: 27.5″: 440g; 29″: 465gBuy DT Swiss Wheels & Tyres from Chain Reaction Cycles.
