Race Face104mm N/W Chainring 10-12 speed(Return to Product Page)

104BCD chainring is common for Shimano cranksets, and product description lists this as suitable for 10-12 speed drivetrains. However, it does not work with Shimano 12-speed CN-M8100 HyperGlide Plus chain. The teeth are too wide for this chain. I ended up having to purchase a different brand of chainring.

The product description should be updated to state it is not compatible with 12-speed HyperGlide+ chains.

Purchased this chainring to convert my wife's 2x10 drivetrain to a 1x11. Fit perfect on the Shimano Deore spider and worked great with the new SRAM 11sp XO1 derailleur, shifter, and chain.

Good quality, no dropped chain.

No chain drop on my mtb conversion from triple to single. Smooth. Happy
