A lightweight rim as wide as a downhill rim was just a couple years ago?
State of the art materials and excessive testing make it possible. DT
Swiss knows exactly how light it can design a product to fullfill its
purpose to perfection. This is why the XM 421 is as light as an All
Mountain rim can get, yet still fears no trail, no matter what rock
gardens it has on the menu.

The current DT Swiss wheels are tubeless-ready and come with mounted tubeless rim tape and corresponding valves. For conversion, you will need a tubeless-capable tire (optimal: UST) and tire sealant. You can find both at an official dealer. Our How To video will take you through step-by-step assembly.
If you have previously ridden your bike with a tube or if the tape no longer sticks properly to the rim, we recommend that you replace the rim tape as a precaution.
How to attach the tubeless rim tape:
1. Measure the inside width of the rim.
2. The tubeless rim tape should be approx. 2 mm wider than the rim and can be bought from a specialist store.
3. Apply the tubeless rim tape. Depending on the rim/tire combination, it may be helpful to apply two or three layers of tubeless rim tape to optimally seal the rim bed.

As wider rims have developed, so have wider tires. However, the different tire and rim widths are not universally compatible. Essentially: The wider the rim, the wider the tires that can be fitted.
The XM 421 will awaken the adventurer in you. These All Mountain rims can accompany you on long outings, on technical single trails or fast rolling fireroads.
