  • Stronglight’s Osymetric chainring is not an oval or an elliptical chainring it is a unique patented twin cam (refers to two curves which are symmetrical about a single point) chainring which has been designed to eliminate the “deadspot/weakspot” which is part of every cyclists pedal stroke due to the design of standard chainrings.

• Manufactured from 7075-T6 aluminium • Available as individual chainrings or as double chainring kit • Required assembly kit included as part of chainring kit or sold separately as: OSAKIT • Finish: Matt Black
