Cross Chaining and Ring Size Efficiency Test
Effects of Cross Chaining on Efficiency and Effects of Chainring Size on Efficiency
Effects of Cross Chaining on Drivetrain Efficiency and Effects of Chainring Size on Drivetrain Efficiency. This test analyzes the frictional losses of the 22 ring-cog combinations of a 2x11 speed drivetrain, as well as the effects of frictional losses based solely on chainring size. 39T and 53T rings were anlayzed, with an 11-28 cassette.
