I think the best sprocket size would be about 24 or 26 tooth, though
I'd be content with 22. Do such things exist? I enquired about it
in Avon Valley Cyclery the other day, they had nothing in stock
bigger than a 17 and were doubtful about being able to get anything
bigger than a 20.

I got a 22 from BikeTrax in Edinburgh <url: http://www.biketrax.co.uk > last
year. They didn't have anything larger at the time, but they had that in
stock, so they're easy enough to find. Aren't 24" wheels under something of
a renaissance in jump bikes at the minute, too?

I recently retired an old bike and I want to convert it into a 3-speed
chain-drive unicycle. I'll keep the existing 28-38-48 chainset and
mount a saddle to the head tube. All that's missing is a wheel. I need
a 26" fixed wheel (not too difficult to come by), but I want a
relatively big sprocket.

I could always use a 20 tooth sprocket with a 20" wheel, but I'd much
rather use a 26" wheel for this project. I could also fit smaller
chainrings, but I'd rather use the parts that I've already got.

And has anyone else noticed that <URL:http://www.sjscycles.com> seems to
be down this evening (Wednesday)?

Yes. Since yesterday I believe. I was going to suggest them as a source
of sprocket as I'm reasonably sure that they go at least as far as 22T.
I don't know if they manufacture sprockets, but the other possibility
might be Highpath Engineering. (Google it).

I have a 22T if you want it. The catch - it's attached to a wheel and
my chain whip is the 3/32" type so won't grip it properly...

St John Street have recently changed servers and are having a settling
period while the location change propagates across the net. Normal
service should resume shortly!

Thanks for the offer, I shall bear it in mind and may well take you up
on it if I can't find something bigger.

Thanks to Ambrose and Jon for their suggestion too, I'll follow them up.
