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.
