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.
