Many many thanks for all the informations! Maybe I will change the shifters for a pair of Campagnolo Super Record that I've found on a Raleigh Pro Team Ti that I've bought for 20$ in a second-hand shop in Quebec City. There was also a Super Recprd RD on that Raleigh. Do you think I should put it on my Bianchi if it fits or the 980 will be as good?
