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.
