Key benefits Comprehensive compatibility: designed for ISCG03 and ISCG05 threaded bottom brackets and integrated with 1x systems for mountain bikes using 3238T chainrings, providing reliable chain retention and smooth shifting on demanding downhill rides. Lightweight construction: produced from aluminum alloy and nylon, weighing 350 g to minimize extra weight while delivering strong performance and stability. chain retention: the design keeps the chain securely in place through rough terrain and aggressive riding, reducing the risk of chain drops and potential drivetrain damage. Adjustable mounting system: flexible mounting orientation options accommodate different sprocket configurations and ensure the chain guard maintains proper clearance from both the chain and crankarms, preventing contact and damage. Use scenarios Downhill and enduro riding with a 3238T chainring setup, where reliable chain retention and consistent shifting are critical on rough descents. Technical trail riding on bikes with ISCG03/05 bottom brackets, requiring accurate alignment and clearance to avoid chain or crank interference. Custom or mixed setups that benefit from adjustable mounting orientation to maintain clearance and compatibility across varying chainlines and crank configurations.
