Product details
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.
- Material ALUMINIUM

Caution when choosing brake pads for wheels with rim brakes!
- Only "SwissStop Black Prince" brake pads may be used on carbon rims.
- Only "SwissStop BXP Blue" brake pads may be used on OXIC rims.
The use of incorrect brake pads can cause the rim to fail. DT Swiss takes no responsibility in this case. Please also note that brake pads which were previously used on aluminum rims must not be used on carbon rims. The aluminum abrasion in the brake pad can destroy the carbon. For further information about your wheel, please refer to the user manual.
If you notice these damage patterns on your wheel, contact a service center.

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.
