These rings are designed for Surly OD cranks but are compatible with other 5-bolt 94 BCD cranks. These rings feature the patent pending Drop-Stop asymmetrical tooth design for the best in wear life mud clearance and chain retention.

Features Wolf Tooth's Drop-Stop tooth design for maximum chain retention

Drop-Stop chainrings are designed for use with 1x9 1x10 1x11 and 1x12 drivetrains

Compatible with all 10- 11- and 12-speed chains with the exception of Shimano 12-speed chains

Shimano 12-speed chains require the use of Wolf Tooth's Shimano 12-speed specific chainrings

If using a 9-speed drivetrain use a 10-speed chain which will provide a tighter fit for better chain retention

Made from 7075-T6 aluminum for long life

Use of a clutch-style rear derailleur is recommended
