going from 7 spd downtube shifters to 8/9 spd integrated???PBWatson

I was told you couldn't upgrade 7 speed downtube shifters to the integrated shifters because of the rear wheel spacing, (axle length is different)
That said I have a cannondale with 7 speed downtube shifters & a 8/9 speed compatable rear wheel slips right in & fits the frame perfectly. Is there any reason I couldn't switch? I know a lot of you will just tell me its not worh it to upgrade & just buy a new bike, but I really like this frame, its light, stiff, fits well & is comfortable.

cannondale is very espensive. so, if your frame can accept the 9 speed hub, why not?? you only have to check rear frame spacing to see if it can accept the new hub.I think it is 130mm.
I only buy new parts if what I own is not working properly.

Some 7 speed frames are 126mm rear dropout spacing and some are 130mm. It sounds to me like yours is a 130mm. Assuming that's the case, new shifters and you should be good to go. Good luck.

I got a couple of old, steel, 6 speed frames and (similar to your case) an 8/9 speed rear wheel fits.

I was told the same thing and I put a 9 speed wheel on my Cannondale too. No problem - go for it.

Make sure it fits with cogs on the rear wheel. You might get the hub to slide in, but there may not be enough space at the end of the chainstay.
