I picked up a used set of Campy Mirage 9speed ergo shifters yesterday for a superdeal, and I want to get them on my 1x9 cross bike (currently bar-end shifted). My goal is to get the setup working with the parts I have, and I am certainly not interested in purchasing campy wheels. Here's the stuff I have on hand:
9 speed shimano cassette (also have a 10 and 8 speed sitting around, if you want to suggest something crazy)
9 speed mirage ergo levers
9 speed ultegra rear derailer
9 speed chorus rear derailer
It seems like the most straightforward thing would be to use the Mirage levers with the ultegra RD and 9 speed cassette, using a shiftmate to make it work, but I can't quite tell which of the numerous shiftmates I need. I've also read stuff saying the shiftmates are unnecessary, and cable routing can do the trick.
What's the best and/or most economical way to go about this? Thanks!
