The original Shimano Deore RD-M610 GS derailleur in black is optimised for Shimano Dyna-Sys technology. The derailleur is designed for a 10-speed sprocket - it has a long GS guide.
A lower Shadow Type profile reduces the risk of damage. Chain tension range is 43 teeth and the largest gear has 36 teeth. It will allow you to change gears very smoothly and silently even during difficult climbs or descents. Can't be combined with a 9-gear system.
