Focus and determination defines you. You are streamlined and efficient. You embrace the most difficult challenges and refuse to give up. You never make excuses, you never stop trying. You conquer mountains from the bottom up, never satisfied with only the descent. You crush the whole loop, every pedal stroke a relentless assault on gravity, your competitors and your personal records. You are XTR and XTR is you. Seriously fast. Confident. Experienced. XTR is committed to rewarding your every effort and has the pedigree to deliver. Dripping with performance, the XTR M9050 drivetrain will not only transfer every watt of energy from pedal to wheel, it will seamlessly shift between perfectly spaced gears allowing you to maintain critical rhythm and momentum over any terrain. You tell yourself you can race without XTR, but you won’t. Never second guess your first instinct.
Shimano XTR Di2 M9050 brings the legendary performace of Shimano XTR into the digital realm. Shimano's game-changing Di2 technology uses powerful digitally-controlled servo motors, which are built into the derailleur bodies, to deliver clean and accurate shifting, time after time. All Di2 componentry is sealed and waterproof, ensuring performance even in the most brutal conditions.
The Shimano XTR Di2 M9050 Firebolt Shifter is the mountain bike shifter, evolved yet simplified. The Di2 Firebolt shift modules are more ergonomic and take up less space than traditional mechanical trigger shifters. Since they are essentially electric switches and lack the mechanical inner-workings of a typical shifter, Shimano was able to minimize the design, cutting away any unnecessary bulk. The Firebolt Shifter's shift paddles feature a contured shape with a grippy texture for a solid connection and responsive feel. The Shimano XTR Di2 M9050 Firebolt shifter can be customized to create your ultimate shifting experience. Using Shimano's E-tube software you can control multi-shift and Shimano Synchronized shift functions, creating custom shift maps and giving you the last word in how your drivetrain responds. In addition to controlling your shifting system, with a little custom setup work in the Shimano E-tube software system, the Firebolt shifter is capable of operating the Fox Racing Shox iCD remote lockout suspension system simultaneously.

I purchased this as part of my XTR di2 build and am disappointed in the quality. It was very tough to get the shifter to stop turning on my bar. I tightened it progressively over several rides and finally the clamp mechanism cracked.
The clamp is a silly, tiny setscrew that pushes against a plate. This is definite not up to XTR standards. I'll warranty it and see if the replacement hangs in.
Bought a slightly used Evil Following with this complete di2 11 speed system. The first 4 rides it was great. On the 5th ride when I pushed on the shifter (normal use, not a crash) the housing separated and it wouldn't shift. In the shop I was able to get the housing back together, but now it sticks occasionally shifting up continuously until in the top gear. I've taken it apart, lubed it, inspected it etc. but can't get it to quit sticking. Not so great on climbs. No warranty because I wasn't the original owner so now I'm faced with the choice of replacing the shifter, or for the same price going with a complete cable shifter....
