XR 391 SBWT Disc Brake Rim

DT Swiss XR 391 SBWT Disc Brake Rim is designed for those who seek a lightweight and efficient XC race rim. With a generous 25 mm internal diameter, this rim enhances both grip and comfort, making it a faster choice for competitive riders. During extensive testing with top athletes like Nino Schurter and Florian Vogel, it was found that pairing wider XC race tyres with the right rim width significantly reduces rolling resistance. The DT Swiss XR 391 SBWT Disc Brake Rim brings this advantage to a more accessible price point, following the success of the World Cup-winning XRC 1200's. The rim bed is optimised for tubeless setups, ensuring quick and easy tyre installation and a secure fit. You can also use standard inner tubes if preferred. Although the rim is as wide as older DH rims, it remains focused on racing, with a maximum system weight of 110 KG. For heavier riders or those needing more durability, consider the XM trail rims.
