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:

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

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.
