The Wolf Tooth 110 BCD 4 Bolt Chainring for Shimano GRX is not only beautifully machined and lightweight but utilises a patented wide-narrow design that is perfectly suited to 1x setups – dropped chains are a thing of the past. Unlock your dream drivetrain configuration and satisfy your inner tweaker.   Bred from ice-cold Minneapolis winters and explicitly designed to work perfectly with Shimano GRX drivetrains, this Wolf Tooth 110 BCD Chainring means more time riding and less time fumbling with dropped chains.   In line with Wolf Tooth’s guiding ethos of providing unrivalled design innovation, reliability and durability, this chainring employs a patented Drop-Stop® wide-narrow tooth profile which not only keeps the chain securely in place on single chainring setups but dislodges mud, dirt and excess precipitation more efficiently. For additional security in extreme conditions, this chainring is best used with a clutch-type rear derailleur.   Features Patented Drop-Stop® wide-narrow tooth profile for minimised dropped chains. Perfect for 1x setups. Machined in-house at Wolf Tooth’s HQ in Minnesota, USA. Beautiful anodised finish.   Compatibility Shimano GRX cranksets including RX600 and RX810. Drop-Stop® FT tooth profile is compatible with 9, 10, 11 and 12-speed chains (including SRAM Flattop). Not compatible with Shimano HG+ 12-speed chains.
