I just installed a Shimano XT cassette (CS-M770 type AS). My question that the instructions specifically show a lock ring spacer yet the box I bought did not include a lock ring spacer. My previous cassette (XT also but 5 years older) did not include a spacer. Am I good to go or is the spacer required?
Currently shifts reasonably well except but needs some fine tuning. I'm just too beat to work on it anymore.
