FR 571 Uncompromising. Blast over rocks, cut through roots and show the trails no mercy. 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, whichever the rider prefers, for full attack mode, or run a big wheel at the front and a smaller one at the back for a mullet setup. No need to be delicate: the brass hex nipples supplied with the rim are tough enough to take a beating again and again. Be bold and brash with a silver rim, or stay stealthy with the classic black. Get yourself a FR 571 and show the trails no mercy.
