Alternatives to pista/track cranksets

You'd likely struggle with crank arm/chainstay clearance, with a MTN frame/ track crank set-up anyway.

Bollocks. Do something insane to anger the bike goods, like mix Campag and Shimano, and your toes will fall off in your sleep. Fact!

I have done this, on a 1950s hetchins curly as well - does this mean I'm going to hell?
