I have a '78 Raleigh Rampar 12 speed I got from my parents but it is waaaay too heavy. I don't need the gears as I ride around in LA suburbs where its pretty much totally flat. I decided a fixie would be the best for me but it's going to be my first one and I'm not really sure where to start. Should I convert my current bike or start from scratch and build it myself? The restrictions are that I have an extremely tight budget as I just moved here and am still unemployed. If starting from scratch is the best or there is a good pre-built bike out there I'd really appreciate suggestions.
it might be a good idea to replace the cranks if they have cotter pins. also, you might want to get an inexpensive set of track wheels, which will also help you shed a lot of weight. remove all excess stuff (rear brake, derailleurs, shifters, derailleur cables, etc). you'll need to pick up a cog and lockring.
So I think I'm just going to go with a temporary single speed conversion for now based on this guy's specs
Here is a couple pics of what I'm working with, I definitely am going to save up for a fixie conversion. Probably keep surfing craigslist for some old frames and keep an eye out for garage sales and such.
