asm I think it might be a good idea for you to get a frame before you start thinking about chainline etc. are you looking to buy a complete bike then strip off the gears etc and fit the fixed rear wheel? you'd save yourself a bit of money if you bought a bike with a decent bb/crankset on it already.
Are you suggesting that I just sort out the rear wheel and modify the standard 2 ring crank with spacers to sort the chain line out to something acceptable. I like the sound of this and it means that I can afford to spend more on the rear wheel and the crank because I can wait a while between them. This leads me onto another question. How do you modify a 2 ring crank to fit nicely with a hub.
