Simple, Reliable and Great Value
It doesn’t get much better for reliability and cost. My last unit lasted 10k miles plus. Super easy to install and tune, extremely smooth shifting.

It’s a Shimano XT, what more needs to be said?
Easy to install on 2021 Specialized Turbo Levo Comp. Shifts great! 12spd….

Inexpensive upgrade for better performance and fun
Came fast, In a New box. Swapped out my original XLT that never would shift smoothly and keeped me guessing. This is one step up and I find its quieter, smoother and dependable so far. Thanks
