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 work with Middleburn X-type (external bearing) cranks only. They will fit on other Middleburn cranks but the chainline will be incorrect. Chainline is 50mm on all rings.

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.

Product weights: 28t - 61g, 30t - 65g, 32t - 70g

All Wolf Tooth Components products are proudly made in the USA!

Middleburn cranks are known for being tough and reliable.  With this direct mount chainring for Middleburn cranks we match that crankset durablity with the highest quality chainring.  


These chainrings are optimized for use with Middleburn X-type (external bearing) cranks.
These chainrings are dished in roughly 10mm 
Can be installed on non- X-Type Middleburn cranks but a longer spindle bottom bracket will need to be used to acheive an optimal chainline
Complementing products:

GCX and GC cassette expanders
