SRAM S500 Eagle DUB Crankset Crank That The S500 has carbon crank arms that keep rotating mass low where it pays off most: out of corners, on punchy climbs, and anywhere cadence changes fast. The 3-bolt aluminum chainring handles chain retention so you can focus on the trail, not on babysitting your drivetrain. DUB spindle technology cleans up bottom bracket fitment across shell standards, seals better against mud and grit, and works forward and backward across the Eagle ecosystem. Multiple chainring sizes let you dial gear range to your terrain rather than settling for a one-size-fits-all setup. Carbon crank arms reduce rotating mass for quicker acceleration and a livelier feel on punchy climbs X-SYNC 2 aluminum chainring uses narrow-wide tooth profiling to keep the chain seated through rough terrain and hard pedaling efforts3-bolt direct mount interface opens the door to third-party chainring and power meter spider options down the road DUB spindle standard simplifies bottom bracket selection, improves contamination sealing, and maintains forward and backward compatibility across Eagle drivetrains Compatible with Eagle Drivetrain Ecosystems from SRAMSPECIFICATIONSSpeeds12BB Compatibility All SRAM MTB Wide DUB BBs, DUB:BSA73, PF89. 5, PF92, PF30 MTB73, BB30 MTB73, BSA MTB68SPChainring Size30T, 32T, 34TCrank Arm Length170mm, 175mm Chainline52. 0mm, 55. 0mm BB Spindle Interface DUBChainring Material Aluminum Bolt Circle Diameter (BCD)Direct Mount (DM)Power Meter No Bottom Bracket Technology DUBChainring Offset3mm Cranksets Type MTB, MTB Wide Chain Technology Eagle Drivetrain Configuration1x Front Tooth Jump0Chainring Mount Interface3-Bolt | Sram | S500 Eagle Dub Crankset 170Mm, 32T, 6Mm Offset (52Mm Chainline) | Aluminum
