Not really. I have a 7-speed set-up on my road bike and, after a crash
and restore, wanted to use the Alivio shifters from a 7-speed MTB on my
road bike. Measured the cable pull ration and it was almost 10%
different. So I still have friction shifters on the road bike until I
transplant the derailer. Which won't be easy since I have a 40T cog in back.
