Rotary?

if you don't know what it is and what history it has, you can still convert it but just don't cut any braze-ons off or cold set the stays. Also keep the gears an shit in a box under the bed or something.

that way you can always convert it back when you realise it's a piece of cycling history.

Fuck this neo-conservationist crap.

It's a bike, not a museum piece, strip the mother fucker to the metal, powercoat the bastard and ride it until it breaks.

Yeah.

Fuck cycling history.
