SRAM AM BB DUB Italian (Road and Road Wide) 70mm (including 2.0, 2.5, 4.5 DUB spacer)We've engineered the SRAM DUB crank spindle to be a true unifying component: one oversized spindle to work across every bottom bracket specification. If you only drink cappuccinos before 11, sing Verdi on long climbs, and named your cat Fellini, the SRAM DUB Italian BB is the ticket for getting our lightest and most durable crank system onto your bike. Better crankarm compatibility, better protection from the elements. With style.
