I've been reading through the 'Danching Chain' chain again. back in the early days racers eschewed pulleys because it was believed they caused drag. Several single pulley designs, including one two pulley that on swung up out of the chain route, after it was all but proved that two worked better at shifting and drag was a non issue.
