S500 Eagle DUB Carbon Crankset - 32t Aluminum Chainring, 55mm Chainline, B1

The SRAM S500 Eagle DUB Carbon Crankset is a modern 1x MTB crankset built for riders who want a lighter, more responsive feel without giving up day-to-day durability. Its carbon crank arms pair with a 32T aluminum X-SYNC 2 chainring to keep the drivetrain quiet and secure under load, while the DUB interface simplifies bottom bracket fitment and improves sealing for longer service life in wet and dusty conditions.

Key performance details for real-world trail use

• Carbon crank arms - Reduces rotating weight for quicker acceleration and a more efficient, direct pedaling feel
• 32T aluminum X-SYNC 2 chainring - Narrow-wide tooth profile improves chain retention and helps maintain consistent engagement over rough terrain
• Eagle drivetrain ecosystem compatibility - Designed specifically for SRAM Eagle 1x setups for clean shifting performance and straightforward pairing
• 3-bolt direct-mount chainring interface - Makes chainring swaps simple when changing gearing or replacing a worn ring
• DUB Wide spindle / 55mm chainline - Optimized for frames specified around a 55mm chainline, improving clearance where wider rear ends, tire volume, or chainstay shapes demand it
• DUB sealing and fitment approach - Aims to reduce contamination at the bearings while maintaining broad bottom bracket compatibility across common standards
