Wolf-tooth Wolf Tooth Elliptical 64 BCD Chainring

The Wolf Tooth Elliptical 64 BCD 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 anything from an MTB to a road
bike, the Wolf Tooth Elliptical 64 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.

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 fit any crankset that has a 64 BCD “small ring” position. This includes standard 104 BCD cranksets,
  the M960 Shimano XTR crankset, the 96 BCD Triple cranksets (e.g. M782) and some others.
• For 1 x 9, 1 x 10, 1 x 11 and 1 x 12 drivetrains (including SRAM Eagle)
• Compatible with all 10, 11, and 12-speed chains except Shimano 12-speed chains.
• If using a 9-speed drivetrain use a 10-speed chain (shifts and works well on a 9-speed drivetrain and fits
  the ring tighter for better chain retention).
• Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud shedding
  ability
• Chainline (approximate as BB centring and cranksets vary) – 47mm on a triple and 48mm on a double crankset
• Ovality of 10% and timing of 112° after TDC (top dead centre)
• Maximum diameter is that of a chainring 2 Tooth bigger than the size you order (so be sure there is adequate
  chainstay clearance!)
