Burgtec Boost Oval Thick Thin Chainring

After years of research and testing of different prototypes where we varied the Ovality percentage, we discovered that 115% is the optimal measurement.

This minimizes pedaling dead spot and maintains chain retention similar to our round chainrings. The dead center decrease allows the power applied to the crank to be recovered immediately.
