E Thirteen Guidering Ring M 104 Blue 2017

Step-up to better chain retention with the Modified Guidering! Optimized tooth profiles and chamfers provide greater chain retention than standard rings. But we didn’t stop there! Months of testing and numerous iterations have yielded a long-wearing shape and finish to make sure your chain stays put even after months of use. 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. 104mm bcd rings feature a flip-flop design that allows for a 49mm or 50mm chainline.
