It may be hard to tell from this photo, but this is actually an elliptical chain ring. Yes this had been attempted in the past with biopace, however they didn’t really have the design right with that version. Elliptical chain rings may sound strange at first, but they can help improve pedal stroke and reduce the weak spots that come along with circular chain rings.
Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile was designed to greatly improve chain retention and help your drive train shed mud easier.
Their 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. Stop by the shop today to check one of these things out. They are wild looking, but really do improve the riding experience.
