Following recent bike misadventures, I'm considering taking up a
friend's offer of an old frame, to turn it into a fixed-wheel bike.

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)?
