Attached is the rear mech that came on my bike.
I know its campag but I have no idea which one.
The rest of the groupset is chorus.
I would like to run this mech on a 9 speed tiagra set up for commuting - so my question is will it run at least 7-8 cogs of the cassette and will it run 25 or 28 teeth?
If not, or if its not going to be a good match, what rear derailleur should I buy, bearing in mind I would like to maintain the bike period etc.
I am going to stick with the downtube friction shifters.
thanks
