The wide/narrow tooth profile of Wolf Tooth chainrings helps prevent chain-drop when running a 1x10 or 1x11 gear setup. No front chain-guide is required provided you have a clutch-type rear derailleur. Wolf Tooth chainrings are machined from 7075-T651 billet aluminum on precision CNC equipment. Say goodbye to bent and misaligned chain-guides and say hello to easy drivetrain setup and maintenance. Best of all, you are not locked into just one drivetrain brand or a specific crankset -- chainrings available to fit almost everything.
These chainrings fit the unique 88mm BCD used on Shimano XTR M985 race crankset. Note that this chainring will not fit the M980 Trail Crankset. The chainline for these rings is 52mm.
Use a 10 or 11 speed chain. If using a 9 speed drivetrain, plan to use a 10 speed chain (it will shift fine), as the 9 speed chain fits too loosely on the ring.
Bolts can be purchased separately. This chainring needs the 6mm (short) bolt+nut combo.
