The minimum would be to replace the rear shifter, cassette, and chain.
Mountain front derailleurs do not pull the same amount of cable as road derailleurs like the 105, so if you bought both shifters you would need a new front derailleur unless you buy a shifter pair specifically made for flat bar road bikes.
If you could find a deal on a complete drivetrain including the crankset, that would be optimal. What's the gearing on that crankset? A standard mountain triple is 22/32/44.
Hello, thank you for answering.
After researching I think so too, it's quite weird setup. (The frame is Bianchi Reparto Corsa 2005 anniversary edition with carbon fork)
Crankset is 30/42/52 (Campagnolo Champ triple). I was thinking of new shifters, cassette and chains from Shimano (Tiagra or 105).
I guess that crankset is ok with Shimano?
