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.

After that car hit me the bike was straightened and it rode fine but would never shift quite right and generally the longer the ride the worse the shifting would get. Finally I eye-balled the rear hanger and it was crooked. Took out the large crescent wrench and straightened it and it shifts perfectly without a hitch.
