I have an older frame with an ultra-6 freewheel. When the rear wheel is removed the stays measure 122.78 (hub is a 120 for the ultra-6). I can cold bend it out to 126, I'm sure, but do I need to if I just put a regular 6-speed freewheel on? I'm not sure how tight that would be as far as the chain scraping the frame. has anybody tried it? Has anybody bent a 120 out to 126 or 130 without problems?
Yep, sounds like I'm making a mountain out of a mole hill. Probably just put a 5-speed on it (if they still make those), or a spacer and regular 6-speed (again, if they still make those!). I think the axle is long enough to handle an additional spacer. It's a great frame, and really comfortable to ride. I don't want to throw it out just because of obsolete / worn out parts. Everything is so different now that I don't know how easy it will be to get parts to fit now or in the future, though. (And I'm not willing to go the overpriced NOS / "vintage" route on E-bay, either)
Thanks for the comments
