Eight speed freewheel compatability

[NeilM]

Simple question: can I fit and 8 speed freewheel on a 126mm hub?

Not sure you can on 126mm? There's a pic on here of an ALAN with a 7 speed block and that's pretty tight but doable.

I'm trying to think if anyone did an 8 speed block with a very narrow chain, Suntour Ultra was only 7 and I think Zenith 8's used normal spacing.

"Spring" or re set the frame?

Re:

That's kind of what I was thinking.

The frame is 130, but I have the chance of some very nice Mavic 500 hubs. Trouble is the 500's are 126mm and for 130mm I really need 501's.

Or, squeeze the frame and run 7 speed.

I'll look for that ALAN.

Funny, just typed and Retrobike disappeared!

This was the thread I was thinking about

Rear 501 axles do appear on the bay from time to time but are stupidly expensive

Yes, I've notices that, which is odd when compared to 500's that go for very sensible money.

Must admit that in the good old days I just slung an 8 speed block on. I don't think I was aware that things shouldn't work like that. It would have been an Sachs block on Campag hubs that were built for 6 speed in 1983. Any help?

Got an unwanted 28 hole Mavic hub. How do I know if its 500 or 501?
Check across the locks nuts so to speak?

Re:

The 501 has a black band around the outside of the hub with MAVIC 501 on it in white.

100mm front, 130mm rear.
