Hi, so i really like STI shifters and especially how they look on lugged steel frames. I have a Univega Ital Sport with nice campy stuff on it. What i want to know is exactly what is needed to to an STI shifter swap?
My wheelset has a 6speed cassette. Now its a bit old and ive been thinking of replacing it, rather than rebuilding it, and in the process going up to an 8 or 9 speed cassette. The wheels are Mavic 22's.
Can i just simply swap on a higher speed cassette? Or do i need to rebuild the wheel for it. Now i also hear this thing about how most older bikes are 126mm spaced, and going STI i would need 130? I not that versed in technical bike talk and all that stuff.
Now i looked at STI's for sale, and most are 10 speed. Now does this mean i HAVE to have a 10 speed cassette out back? OR does it mean that its 10 speed at most. What if i have 8speed and use a 10 speed brifter, would that work?
These are the kinds of questions I have, and also what i would need to modify.
I also noticed that Nashbar just came out with their own STI system, and it looks nice and they sell it for only $179. might give that a try.
