The Wolf Tooth 110 BCD Asymmetric 4-Bolt Chainring for Shimano Cranks is not only beautifully machined and lightweight but utilises a patented wide-narrow design that is perfectly suited to 1 x setups. Bred from ice-cold Minneapolis winters and explicitly designed to work perfectly on anything from a cyclocross, gravel or road bike, this Wolf Tooth 110 BCD Chainring means more time riding and less time fumbling with dropped chains. 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 Fits 110 BCD Asymmetric 4-bolt cranks. Compatible with Dura Ace 9000, Ultegra 6800, 105 5800, Tiagra 4703, and Tiagra 4700. Sizes 38T and larger are compatible with Dura Ace 9100, Ultegra 8000 and 105 R7000 but a slight modification is required due to a change in the crank arm profile. The 36T chainring will not work for this modification. Click here to see Wolf Tooth's instructions for the modification.. Confirmed modification fit with Dura Ace 9100 Power Meter in size 42T or larger. Mounts in the big ring position of the cranks but is offset inward for perfect chainline.. The stock 2x bolts will not work. You will need our 6mm bolts which are optimized for single ring mounting.. Drivetrains: 1x9, 1x10, 1x11 and 1x12 drivetrains. Compatible with all 10-, 11-, and 12-speed chains except Shimano 12-speed chains. Shimano 12-speed chains require the use of our Shimano 12-speed specific chainrings. If using a 9-speed drivetrain use a 10-speed chain. It fits tighter for better chain retention. Chainline 47.5mm.
