So I've got this old Miyata 610 that I'm starting to work on. Thanks to some of the other posts around here I got curious and went out and measured the frame spacing only to find that it's 120 mm. I'm thinking I'd like to re-space this to 126 and run with my old but still freehub equipped 105 hubs and 7 speed cassettes. Now I've also got some wheels with freewheels on them but they are all "no name". But with 6 speeds it would/should fit the current 120 mm. But from what I've seen the freehub setup is a little more stiff thanks to the wider bearing spacing and less axle to flex.

Thoughts on this?
