Hard rocks or horizontally lying roots: This rim masters every challenge. The FR 571 has everything it takes to conquer the Black Snake and jump gaps.

The integrated hex nipples made of brass are extremely robust and suitable for the most demanding trails. Make a statement with a silver rim or stay discreetly in the background with a black rim. The FR 571 – for those who can take it tough.
