Not sure if this is the answer you are looking for. I removed my 9 spd Altus and replaced it with a 9spd Shimano XT rapid rise derailuer. I'm using Microshift 9 speed indexing thumb shifters that work great with11- 36 cassette Front derailuer is friction. Silver 38×24 cranks I did not have to do anything to the chain length. I really like having front & rear shifters move the same way for high and low gears.
