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.
Our 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 38t chainring feels like a 36t in the weak part of your pedal stroke and a 40t in the part of the stroke where your legs have the most power.
These rings are for use with Shimano 110 BCD Asymmetric 4-bolt cranks. Here is how to measure your BCD.
Compatible with Dura Ace 9000, Ultegra 6800, 105 5800, Tiagra 4703, and Tiagra 4700
Mounts in the big ring position of the cranks but is offset inward for perfect chainline.
For 1x9, 1x10, 1x11 and 1x12 drivetrains (including SRAM Eagle)
Compatible with all 10, 11, and 12 speed chains (Including SRAM Eagle)
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).
Chainring bolts - we recommend our 6mm bolts which are optimized of single ring mounting
Tanpan - allows Shimano mountain bike rear derailleurs to be used with Shimano road shifters
RoadLink - allows for wide range cassettes to be used with Shimano road rear derailleurs
Design and manufactured in the Minneapolis, MN USA
Wolf Tooth’s patent pending Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud shedding ability
Recommend the use of a clutch style rear derailleur for the best chain security.
Colors - black
Chainline - 44mm
If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur! Without these precautions, you may experience chaindrops and/or chainsuck.
Weight - 38t - 66g, 40t - 74g, 42t - 81g
