Shimano's LX M585 has the dual control integrated brake-shift lever design which is operable with Shimano's new LX hydraulic disc brake system. The shifters are 9 speed and are provided with optical gear indicators
One of the most exciting new functions of the redesigned LX group is seen in the new Dual Control Lever. It lets you shift gears up or down, from various hand positions, allowing the rider to focus on the trail. The secondary release lever provides another shifting option that is a great "transitional" feature as you become accustomed to dual control shifting and can be removed if desired for the ultimate "clean" set-up. specifically designed to work with hydraulic disc brakes. k
