Compatibility and fit: Designed for ISCG03 and ISCG05 threaded bottom brackets, this chain stabilizer integrates seamlessly with 1x systems. The adjustable mounting orientation matches your sprocket size, ensuring the chain guard never contacts the chain or crankarms and helps prevent damage. Lightweight and strong: Built from a aluminum alloy and nylon, this chain guide weighs 350 g. The design minimizes overall bike weight while delivering the strength needed for demanding downhill and aggressive riding conditions. Reliable chain retention on rough terrain: A singleplate downhill chain stabilizer engineered for 32T38T chains keeps the chain securely in place on bumpy, technical descents. It effectively reduces chain drops and derailments that can interrupt your ride or harm drivetrain components. Full drivetrain protection: The enclosed design shields valuable drivetrain components from rocks, boulders, and protruding roots. This protection helps extend the life of your chain and sprockets while giving you confidence through challenging terrain. Use scenarios: Downhill or enduro riding on rocky, rooty singletrack where chain retention matters. Aggressive trail riding with a 32T38T drivetrain setup, including speed descents. Bike park days or rough trail sections where extra protection and reliable chain retention are beneficial.
