I understand that many people think MTB and road bike derailleurs and index shifters are not compatible and I understand that may prove to be the case with my Tourney shifter. What you don't understand is that I have made it work in the past, with my Sora road bike shifter, without any trouble at all. So, we'll see. If it doesn't work, then I have a much bigger problem than I want. So, fingers crossed.
