Shimano wrote the book on superior shifting, and their Deore XT Rear Shifter carries that trend forward with the company's trademark precision, light action, and real-world durability. Shimano's 2-way release operation means you can pull or push the shift levers, keeping shifting remarkably easy and intuitive. The Dyna-Sys rear shifter is 10-speed compatible for close ratios and crisp shifts under all conditions. And, this shifter also includes an easily removable optical gear displays for heads-up gear monitoring at a glance, or a sleek, pared down look.
