e*thirteen Direct Mount SL Guide Ring 38T Narrow Wide Black

From their previous Guidering M, e*thirteen were able to shave 11 grams off with their SL Chainring while still increasing fold-over strength and impact resistance.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, 11, or 12 speed rear derailleur and proper drivetrain protection, youll be ready for anything the trail throws at you.SL Guiderings are machined with a -8mm offset and work with BOTH boost and non-boost chainlines, depending on spacer orientation of Gen 3 and 4 e*thirteen cranksets.
