Deore XT is a mountain and touring bike groupset first introduced by Shimano in 1983.[1] It was Shimano's first mountain bike groupset, based on their existing Deore touring groupset, and it consisted of a triple-, double- or single chainring crankset, front and rear derailleurs, handlebar-mounted "finger" shifters, cantilever brakes, and large-flange hubs.[1] Since then, it has become their "second-tier" offering, the list of components has expanded to include hydraulic disc brakes, a complete wheelset, a chain, and clipless pedals,[2] and it is offered in silver or black finish.[3]

Model history

The groupset was designated by model numbers M7xx; beginning with M700,[1] and ran to M780.[4] Touring groupsets were designated by model numbers T7xx. Current groupsets are designated by model numbers M8000 and T8000.

    • RD-M770, 9 speed, reversed spring
    • RD-M771, 9 speed
    • RD-M772, 9 speed, Shadow profile

    • Rear derailleur: introduction of Shadow Plus technology, which added a switchable clutch used to stabilize chain tension. Shimano has released two versions of the rear derailleur - M781 (without clutch) and M786 (with clutch). Both versions were sold in two cage length options - GS (medium) and SGS (long, 95 mm between centres of jockey wheels axis).
