The Shimano M9050 System Information & Display Unit helps you keep track of your every move on the trail. With a quick glance you can see your current gear selection, shift mode & battery life. With the ever expanding E-tube platform the display also means that you can view your Fox suspension position, whether you are in climb, trail or descend mode you will always be prepared for the trail ahead. The customized Synchro-shift modes can be selected between S1, S2 & Manual on the fly by using the mode button. You also get an audible shift notification tone when in Synchro-shift mode, alerting you the front derailleur is about to shift. An easy access adjustment mode button means fine tuning either of your derailleurs is now effortless.
