FR 571 Uncompromising. Smash through rock gardens, slice over roots and show the trails who's boss. The FR 571 has everything it takes to conquer the "black snake" of Val di Sole and fly over desert canyon gaps. Attack the trails on 29?? or 27.5??, depending on rider preference, whether you want to be fully in attack mode or go for a bigger wheel at the front and a smaller one at the back. No need to be gentle: the brass hex nuts included with the rim are tough enough to be thrashed again and again. Be bold and brash with a silver rim, or stay stealthy with the classic black model. Get yourself a FR 571 and show the trails who's boss.
