Wanted: Cheap bike for conversion

Bernhard Re: Half chainring bolts, these are bolts that are shorter than regular chainring bolts that are designed to go through 2 chain rings and the crank, half chainring bolts are used for single chainrings and the crank. I expect PJ built a new rear wheel for the bike using a track hub.

bernhard - your powers of deducution are amazing

thanks very much for the half chainring bolts explanation
