Sun Ringle Duroc SD37 Rim - 27.5", Disc, Black, 32H RM3722

Rim strength comes from the careful combination of bead hook width, sidewall thickness, and spoke bed thickness. Whether you're on the race track or at the top of a questionable descent, lowering your tire pressure to compensate for technical terrain control can require additional rim armor where it counts to make it through the day. Duroc SD is the solution for racers, freeriders and everyone in-between.
