Description

The SHIMANO XT RD-M781-SGS 10-speed Long Cage Rear Derailleur adopts a low-profile design thanks to SHIMANO SHADOW RD technology, designed for more aggressive riding on narrow, technical trails. Its single-tension design prevents any contact with the frame chainstay, even on rough terrain, for smooth and quiet operation.

Compatible with DYNA-SYS, the RD-M781 delivers efficient shifting in both 2x10- and 3x10-speed configurations, while preserving cassette, chain and chainring life through optimised gear ratios.

Its long cage (SGS) offers a total capacity of 43 teeth to cover wide cassette ranges. Made from aluminium, this DEORE XT M780 derailleur combines precision, discretion and reliability for demanding mountain bike use.
