Thanks for the greeting, Bill)

In Russia, bicycles from old frames are popular, they are called "crocodiles". Most often, the old (up to 1991) frames of the Soviet factory XB3 - Start-Shosse, Champion, Tachyon, etc., with using many modern spare parts, but metric threads and diameters limit the choice of quality equipment.

The more interesting is to assemble a bicycle based on Reynolds pipes, because inch sizes allow you to choose not from what is available, but from what you like.

The conversion of the this frame into a single-speed does not in any way concern the change in its shape, it remains all "as is", which is especially valuable for me )
