Details / Wolf Tooth 32t 104BCD Drop-Stop Eliptical Chainring - Black

We won't try to convince you that elliptical (or oval, the same thing) chainrings will change your life...but they might!  What we can say for sure is that they provide an efficiency benefit and smoother power output.  With this, you will experience the benefits of better traction, especially with technical climbing, and faster acceleration.

Wolf Tooth's proprietary design has ovality of 10% and timing of 112° after TDC (top dead center). These values provide the benefits of an oval ring without the drawbacks of greater ovality or more aggressive timing.  

The simplest way to explain how they "feel" is that where your pedal stroke is weakest it feels like you have a 2 teeth less on the chainring and where you have the most power it feels like you have 2 more teeth.  They feel this way because with the radius of the chainring constantly changing, the torque needed to turn the cranks is constantly changing to better match your power output.  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.


  • These rings fit any 104 BCD crankset, and here are instructions on how to measure your BCD.  
  • For 1x9, 1x10, or 1x11 drivetrains
    • Compatible with all 10 and 11 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).

These will fit most common cranksets using 104 BCD mounting but if you have a Shimano Double M785 XT or M665 SLX double crankset you'll want to follow these instructions from Wolf Tooth to get them to fit. Also, even if you're running a 9 speed drivetrain, plan to use a 10 speed chain (it will shift fine), as the 9 speed chain fits too loosely on the ring.
