Always Read The Description Before Placing The Order!
Remember at anytime Shimano can alter what is included with the next Generation so please read the original description first before placing your order. But this is what came in my box. I had all the Ultegras at one time & i used the 5500 CI4 unit the most. To me it was the sturdiest.
