CeramicSpeed claim the new Driven drivetrain is 99% efficient. Wonder what the tech specs of the old Columbia Chainless were...



The 1898 Columbia Chainless Model 51 featured a shaft drive. Benefits included no chain slack, less exposure to dirt and no chance of getting tangled in the chain (similar reasons for belt-drive), which was especially attractive to women, who were almost exclusively riding in skirts or dresses at the time.
