FR 571 Uncompromising. Smash through rocks, cut through roots, and show the trails who's boss. The FR 571 has everything it takes to conquer the "black snake" at Val di Sole and fly over canyon gaps in the desert. Attack the trails on 29" or 27.5" wheels, rider's choice, for all-out attack mode, or run a big wheel at the front and a smaller one at the rear. No need to be gentle: the brass hex nipples 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 an FR 571 and show the trails who's boss.
