ABSTRACT:
A belt drive transmission is disclosed which comprises a first gear, a second gear and a belt. The preferred embodiment is for a bicycle transmission which employs a plurality of gears in place of said first and second gears and employs a derailer to move the belt among selected gear ratios. A novel design of gears and a derailer permits the transmission to employ lighter materials thereby reducing the overall weight associated with a transmission.
