- Type and mounting standard: ISCG 05 with 55.9 mm distance between mounting holes. Suitable for frames and guides that follow the ISCG 05 spec. - Chainring compatibility: Supports round chainrings from 30T to 40T and oval chains from 30T to 38T. Allows flexible setup for different riding styles and chainring shapes. - Weight (variant specific): approximately 25 g for the ISCG03 version, approximately 29 g for the ISCG05 BB Axle Mount version. Lightweight design to minimize added mass while maintaining chain retention. - Function: Chain guide to keep the chain aligned with the chainring and prevent derailment during aggressive riding and rough terrain. - Use scenarios: - Enduro and trail riding on rocky or uneven terrain where chain drops are common, helping maintain pedal efficiency and control. - Downhill and gravity-oriented riding that involves big impacts, jumps, and quick gear changes, reducing chain bounce and drop risk. - Upgrading an older bike or configuring a 1x drivetrain on a frame that uses ISCG tabs, ensuring reliable chain guidance and compatibility with common chainring sizes.
