Osymetric is a French make of ovoid bicycle chainring which has a non-circular shape whose angle is tailored to the pedal stroke of the individual cyclist. These were designed by engineer Jean-Louis Talo who claims that this improves cycling performance. Such chainrings were used by professional cyclists Bradley Wiggins and Chris Froome for their Tour de France victories.[1][2]
