If you run into weird issues where it won’t shift the full range:
Check to ensure the FD is in the big ring. Cross chain prevention does not allow it to go into the last two gears if the FD is in the small ring.
Refer to Nomutze’s post above. Some times the RD needs to be manually moved out board to the smallest sprocket. This can only be done thru fine tuning.
Lastly, for any fine tuning adjustment to take place, you shift to the gear you are adjusting, make the adjustment, then shift up or down and back to the gear you adjusted. For every fine tuning you must shift in order for it to take.
