I wasn't suggesting bending the frame (a PITA when changing the wheel
if nothing else) but getting a shop to reset the rear to a different
width.

My main concern is that the bottom bracket will be too low and I'll
keep catching the pedals on the ground, something that I've done

What else do I need to consider?

I konw it needs to have horizontal drop-outs. What about axle spacing?

consider spd pedals, you'll get cornering clearance, and loosing a pedal
because you forger you were on fixed is much more difficult ;) If you
need conventional pedals fit the thinnest and narrowest you can find.
Shorter cranks or a nice fat tyre will help a lot.

Fat tyres, no thanks! But yes, of course I would have SPDs.

You can bend an old steel frame to any hubwidth you want, but hubs are
available from 110 to 135mm

I thought bending was bad for frames, and was not advised. In fact in
the days when six-speed hubs were new, I remember reading strong
warnings not to try forcing them to fit by bending.

You shouldn't bend aluminium frames, they don't like it and are prone to
snap. Not so much of a problem with steel.

He says it's an old touring frame with "relaxed geometry".

I've just picked it up.

It's a Gudereit frame, "Veloring Esklusiv". A sticker on the seat post
says "25 CrMo 4".

There's another sticker indicating it might date from 88-91 (or maybe
that's when it was sold).

It has braze-ons for just about everything you could imagine, from a
kick-stand to mud-guards and dynamo.

The drop-outs are horizontal; the distance between them is 126mm.

Does that sound like a worthwhile candidate for turning into a
fixed-wheel bike?

not if you insist on 23mm tyres

Why is that?

Is it because fatter tyres will make the necessary difference to pedal
clearance (and wouldn't shorter cranks solve that problem)?

it's probably designed with a lowish bracket and for 37mm tyres. 15mm
shorter cranks is quite a lot, and for what? Decent running 35mm's will
hardly be slower, much more surefooted if the roadsurface is bad, more
comfortable....

Check the bottom bracket height, as I discovered recently.

Thanks for the cranks. Now to find out if the old cotter pins will
fit, and where to get new ones from now Drake's have closed if not....

Sorry. I did not retrieve the extracted cotter pins. SJSC sell cotter
pins, FWIW...
