The Truvativ Descendant All Downhill crankset in 170mm is built for bikes with wider 83mm bottom bracket shells, common on older and plus-tyre downhill frames. The DUB83 spindle gives you a stiff, modern DUB interface on wider shell bikes, with 170mm arms offering a balance of ground clearance and pedalling leverage for taller riders.

• DUB83 spindle for wider 83mm bottom bracket shell frames
• 170mm crank arm length — balanced clearance and leverage for taller DH riders
• 34t X-SYNC 2 Direct Mount chainring delivers reliable chain retention through rough terrain
• 12-speed SRAM Eagle drivetrain compatible for maximum gear range
• Forged alloy construction engineered for downhill loads and impacts

Designed specifically for downhill use, the Descendant All DH uses a forged alloy platform that handles the high-impact forces of jump lines, rock gardens and steep descents. The 34t chainring paired with Eagle's 10-52t cassette gives you a wide range suitable for the flattest fire roads and steepest DH tracks.

Compatible with SRAM DUB83 bottom brackets (sold separately). For 83mm shell downhill frames running 12-speed SRAM Eagle drivetrains.
