Not much BSW I wouldn't think, but probably plenty of BSF and BSCY. BSW is too coarse for general use on a vibrating bike...

If you measure the diameter and pitch you can determine the thread from this web site

Hi Graeme,

Most of the cycle threads (called, by the way, BSC, BSCy, or occasionally CEI) will be 26 tpi from 1/4 to 1/2". However watch out for the occasional 20 tpi thread in sizes like 7/16 or 1/2" - these are also cycle thread even though you will be told they are American UNF). As Rex suggests you might also find some BSF. BSW will only appear where threads are tapped into aluminium alloys (crank case end of barrel studs, base of magneto) and maybe a few 1/4 odd bods here and there.

The hexagon sizes are likely imperial (BSW/BSF).

Just a thought. Where the O/P referred to "BSW" I wonder if he was using BSW as the generic interchangeable (and incorrect) term for "Imperial" as Americans (for example)  always seem to do?
You there, Graeme?

Some TV quiz recently said somebody set up making pushbikes in Raleigh Street, Nottingham.
Are there any other vehicles named after places?

That´s the best answers I´ve ever had to a question and it wasn´t even my post!  I was thinking of Leyland when I said vehicle. Rex, I have ridden on the beach at West Hartlepool. There are probably French named engines as well?
Thanks for all your replies.

Brockhouse made the Indian brave, I think in Southport?, I seem to remember they made agricultural machines.
My mate has restored a Brave, looks a bit like a C11 without my specs.

And I'm guessing Sun were not made on our nearest stellar body... perhaps in Wapping though.

Quick question here, just new on here but was there a big number of Raleighs built, I'm about to start restoring a 33 that is in a pretty bad state of disrepair. I've been putting it off for years
