S500 Eagle DUB Carbon Crankset - 32t Aluminum Chainring, 52mm Chainline, B1

The SRAM S500 Eagle DUB Carbon Crankset is a modern 1x mountain bike crankset built to balance low weight, consistent pedaling feel, and reliable chain control. Its carbon crank arms reduce rotating mass while the 32T aluminum X-SYNC 2 chainring is designed to keep the chain settled under torque, rough terrain, and rapid cadence changes.

With a 52mm chainline and DUB spindle standard, it’s a practical upgrade or replacement for riders who want straightforward fitment, strong sealing against trail contamination, and seamless compatibility with the SRAM Eagle drivetrain ecosystem.
