You've probably seen one of these "ovalized" chainrings by now, and have been slapped in the face by curiousness like most of us have. Do things really make a difference in efficiency? The master minds over at Wolf Tooth Components aren't promising you a pair of wings here, but they aren't hesitant to relay that these elliptical rings do in fact have a much different feel to them that can provide more efficiency and a smoother power output. Their team of testers report the most noticeable benefits come on punchy singletrack and hills, allowing less shifting and snappier acceleration.
Wolf Tooth's take on the Elliptical chainring has an ovality of 10% and timing of 112 degrees after TDC (top dead center). What this does is eliminates 2 teeth where your pedal stroke is the weakest and adds 2 teeth where your stroke exerts the most power. For example: a 34t chainring feels like a 32t in the weak part of your pedal stroke and a 36t in the part of the stroke where your legs have the most power.
This model of Wolf Tooth's Elliptical Chainring is threaded for M8 chainring bolts with built-in 2mm standoffs. With this 2mm offset, the chainline is roughly 48mm on a triple crankset and 50mm on a double crank (varies by crankset).
Note: Use a 10 or 11 speed chain. If using a 9 speed drivetrain, plan to use a 10 speed chain (it will shift great), as the 9 speed chain fits too loosely on the ring.
