Wolf Tooth Elliptical 110 BCD Flattop Chainring

The Wolf Tooth Elliptical 110 BCD Flattop Chainring 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 1X setups, the Wolf Tooth Elliptical 110 BCD Chainring means more time riding and less time fumbling with dropped chains. Primed for 12-speed SRAM flattop 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.

PowerTrac

Wolf Tooth’s PowerTrac Elliptical (PTE) design, as the name indicates, is driven by a concern for power and traction – and crucially for you, premised on a wealth of knowledge from precision engineers who also love to ride bikes.

A growing number of riders are converting to elliptical chainrings on 1x setups for the simple reason that they have been demonstrated to improve ride quality.

The idea behind elliptical chainrings can be summarised as follows: biomechanical power output varies throughout a pedal stroke, at positions where power is higher, having a larger diameter section of chainring, and thus greater engagement area, translates into greater forward propulsion. At positions where biomechanical power is lower, a smaller chainring diameter means greater efficiency in rotation. Overall what this means for you is maximised power output throughout each pedal stroke.

Wolf Tooth note that elliptical rings also mean steadier torque on the rear wheel as there is less spinning on the downstroke and easier rotation in between these. Steadier torque on the rear wheel gives better traction and sustained momentum – great on tough climbs and through headwinds.

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

• These rings are for use with 110 BCD 5 arm cranksets.
• Crank arm clocking arrow will be rotated 180 degrees from normal on cranksets that have 4 bolts visible and 1 hidden bolt behind the crank arm (SRAM). When mounting, be sure the arrow on the chainring goes behind the crank arm.
• Do NOT fit on the cranksets for Shimano DA 9000 / Ultegra 6800
• Not compatible with Campagnolo CX10/11.
• Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud shedding ability
• 10, 11, & 12 speed Eagle and Flattop - These chainrings are designed to work with all 10-speed and 11-speed chains. They also work with 12 speed SRAM Flattop, SRAM Eagle and KMC chain. They do not work with Shimano 12 speed Hyperglide+ chain.
• If using a 9-speed drivetrain use a 10-speed chain. It fits tighter for better chain retention
• Chainline - varies - these rings can be mounted in either the big or small ring position on double cranksets. The most common mounting is in the big ring position because of chainstay clearance. The ring centerline is ~2mm from the ring's mounting face so they usually sit about 2mm closer to the frame than the stock big ring (depends on the stock ring)
• Can be mounted in either the big or small ring position of a double crankset given chainstay clearance in the small ring position.
• Stock 2x bolts will not work. You will need 6mm bolts which are optimized for single ring mounting.
