The anodised finish and machined lettering that adorn every chainring bear the hallmark of master craftsmanship.PowerTracWolf 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,Elliptical design,Perfect for 1x setups,Machined in-house at Wolf Tooth’s HQ in Minnesota, USA,Beautiful anodised finish,.Compatibility:Compatible with Dura Ace 9000, Ultegra 6800, 105 5800, Tiagra 4703 or 4700, Sora R3000 or R3030, and Claris R2000 or R2030 cranks. ,Drop-Stop® FT tooth profile is compatible with 9, 10, 11 and 12-speed chains (including SRAM Flattop),Not compatible with Shimano HG+ 12-speed chains,.
