drivetrain upgrade question -(2 posts)

drivetrain upgrade question -the greek
Jun 19, 2003 6:50 PM
I'm riding a steal frame vintage Paramount ('91) with 7 rings in the back. If I move up to 9 speed stuff can I bend the frame or will it cause too much stress on the rear triangle?

I know I should buy a new bike but it's just a training ride.

you can spread steel frame. Shedon Brown has an article on how http://www.sheldonbrown.com/frame-spacing.html
I've re-spaced several frames and it isn't hard but pers I wouldn't do it to classic bike. People spending time restoring those.
