While you probably don’t love new chainring fitments, you gotta love how quickly Wolf Tooth Components is able to turn out new products. The latest of which are new 1x rings for Shimano’s GRX cranksets.
Even though Shimano already used a 110 BCD with asymmetric bolt placement for their road cranks, GRX chainrings use a different offset and a different tab layout. That means another chainring design had to be created by WTC in order to fit the new gravel cranks from Shimano.
The 110 BCD Asymmetric 4 bolt ring for Shimano GRX is designed to match the GRX aesthetics and is available in 38, 40, 42, 44, and 46t to provide more gearing options than stock.
The rings also feature WTC’s Drop-Stop FT profile which works with all 10 and 11 speed chains, as well as 12 speed chains including the SRAM Flattop, SRAM Eagle, and KMC chains. They do not work with the new Shimano Hyperglide+ 12 speed MTB chains, but since GRX is still an 11 speed group, they’ll work just fine.
Machined from 7075-T6 aluminum in the USA, the rings have a claimed weight of 72-102g depending on the size and are priced from $79.95 to $84.95.
