Wolf Tooth Elliptical Direct Mount Chainring for Shimano 12 Speed Hyperglide Drop Stop ST / Boost (3mm Offset)

The Wolf Tooth Elliptical Direct Mount Chainring for Shimano Cranks with 12-speed HyperGlide+ Chain is not only beautifully machined and lightweight but utilises a patented wide-narrow design that is perfectly suited to 1x set ups – 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 12-speed HyperGlide+ chains, this direct mount 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.

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. Positions where power is higher have a larger diameter section of chainring and thus a greater engagement area, which 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 notes that elliptical rings also mean steadier torque on the rear wheel as there is less spinning on the downstroke and easier rotation as a result. 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.
