Bike Derailleurs

The derailleur controls the shifting of the chain from gear to gear. The rear derailleur controls the shifting from one rear cassette cog to another. The front derailleur controls the shifting from one front chainring to the other. Derailleurs are typically controlled via shifters mounted on the handlebars. Derailleurs and shifters are normally manufacturer specific regarding compatiblity, so Shimano derailleurs are not compatible with the majority of SRAM shifters.
