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 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 on anything from a cyclocross, to a gravel or road bike, 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.

Synonymous with ultra-high-end custom builds and stalwart steeds alike, Wolf Tooth chainrings are machined entirely in-house at Wolf Tooth’s HQ in Minnesota, USA. The anodised finish and machined lettering that adorn every chainring bear the hallmark of master craftsmanship.

If you’re a discerning cyclist looking to invest in a premium-grade chainring that’ll outlast its competitors and function perfectly on a 1x set up, this is the only way to go.

Key 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

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. 


• 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.
