Wolf Tooth Elliptical 1x Chainring for Shimano GRX Cranksets

Designed specifically by Wolf Tooth to fit Shimano GRX crankset only, including GRX RX600 and RX810 models. Does not fit other Shimano cranksets. Tooth profile is Wolf Tooth's "Drop-Stop B" wide/narrow pattern for excellent chain retention and mud shedding in challenging conditions. 

This model is elliptical (oval) and comes in the 4 bolt, 110mm assymetric BCD mounting pattern. 

  • Drop-Stop "B" Profile - optimized for use on drop handlebar gravel or cyclocross bikes
  • Drop-Stop "B" works with ALL 9, 10, and 11 speed chains, plus select 12 speed models: SRAM Eagle, Campagnolo, and SRAM Flattop AXS chains
  • Drop-Stop "B" DOES NOT WORK with Shimano 12 speed HG+ chains - please use a Drop-Stop ST chainring for use with Shimano 12 speed HG+ chains

These rings are machined from 7075-T6 aluminum for a long lifespan, and weigh in at a paltry 72 grams (38 tooth model), 92 grams (42 teeth), or 102 grams (46 teeth). Like other Wolf Tooth products, proudly made in the USA.

Drop-Stop chainrings have excellent chain retention and don't normally require a chain guide or chain keeper; however, riders in very muddy conditions are suggested to use a chain keeper + clutch rear derailleur to reduce chain drops or chainsuck.
