Fitting a 126mm wheel to a 130mm-spaced frame

[C. Peak]

Hi,

Does anyone know if it's possible/recommendable to fit an
old 7-speed 126mm hub on a big-tubed aluminum frame with
130mm spacing between the dropouts? I'm thinking about
buying a used Cannondale frame to fit my components from an
older bike, but am a bit trepidacious about bending the
frame. I've done a few google searches but every similar
post seems to be about fitting a wider hub to a narrower
frame -- not the other way around.

By the way, yes I have considered the option of somehow
widening the rear hub, but am not entirely sure if this is
possible either. It's a freewheel, not a cassette.

Thank you for any input on this, CP

"Many people will tell you that this requires a new axle,
but if you're only going from 126 to 130, this is not true.
The 137 mm long axles commonly supplied with 126 mm hubs are
plenty long enough for use with 130 mm spacing. There is
absolutely no risk to this."

I assume that what he writes about respacing a 126 to 130
would apply to a freewheel hub, also. Simpler, actually.
Adding 2mm spacers on each side will mean no redishing.

Just add a 2mm washer to the outside of each of the bearing
locknuts, and you will have a perfect fit.

It's easy to widen the hub width by adding spacers. Where to
put the 4mm worth of spacers depends upon whether you want
to readjust the rear derailleur or re-dish the wheel.
