Compatibility and purpose Fits ISCG03 and ISCG05 threaded bottom brackets and is designed for 1x drivetrains to improve chain retention and drivetrain reliability. Material and weight Constructed from ABS plastic to keep weight low while maintaining strength and durability. Protection and reliability Enclosed design shields the chainring area from rocks, boulders, and protruding roots, helping you ride with confidence in rugged terrain. Adjustability and fit Mounting orientation is adjustable to match your sprocket setup, ensuring proper chainline and preventing contact between the chain guard and the chain or crankarms. Key benefits Reduces chain drops and chain derailments on rough trails. Lightweight yet robust, preserving overall bike weight and performance. Simple, reliable protection that works with a variety of 1x configurations. Use scenarios Technical rocky descents on a 1x setup where chain retention is critical. Crosscountry or enduro riding on loose or debrisfilled trails where debris can otherwise affect performance. Rides with larger sprockets or unusual chainlines, where adjustable mounting allows precise clearance and reduces the risk of contact with the chain or crankarms. Installation and compatibility notes Designed for ISCG03 and ISCG05 threaded bottom brackets; no changes to crank or frame geometry required. Adjustable mounting allows for a customized fit based on sprocket size and chainline to maintain protection without interference.
