GUIDERING M – BOOST

Step-up to better chain retention with the Modified Guidering! Optimized tooth profiles and chamfers provide greater chain retention than standard rings. Coupled with a clutch-style 10 or 11 speed rear derailleur and proper drivetrain protection, you’ll be ready for anything the trail throws at you.
For use with e*thirteen cranks only.
