I have 1999/2000 Torelli Gran Sasso. It is a 9-speed. It has a triple crank setup with a variety of Campy components and I want to convert it to a double. I am going to use components from the same time frame (around 2000) so hopefully none of the current QS configuration needs to be considered. The shifters right now are Daytona and I am going to try to make the bike primarily Daytona or Centaur as a double. Can I continue to use the shifters with the double crank setup or do they have to be changed?
As a followup to my first question, if I wanted to go 10-speed on this bike, can I assume since it handles 9-speed componentry, it will also handle 10-speed? If not, what do I need to confirm in measurements, etc. to be certain that the bike will accomodate a 10 speed Campy setup? Thanks for any info!
