First Fixed Gear Conversion: pt II, Deciding What to Do with It

The first step in any project is to plan it. With this conversion, it's deciding which parts I'm going to keep, which will be replaced, and what other restoration may need to be done.

The frame does have a couple small scratches with rust. Also, basically all the "Raleigh" and "Grand Prix" decals have been worn off, or at least to a point where they don't look good. Naturally, it needs a paint job. I'm leaning towards powder coating for the improved durability.

I'd like to keep as many parts as possible, so as to keep costs down. All I'll be replacing is the back hub and chain (at least for the time being; I'll probably replace the cranks later). I'll replace the back hub with a flip-flop hub and a 1/8" cog, as I've heard the full bushings used in 1/8" chains make them much more durable, though it sacrifices flexibility (not needed on a single gear). Until I replace the cranks, I can ride the 1/8" chain on the 3/32" chainring. I would replace the chainring and keep the cranks, but the chainring is permanently connected to the drive-side crank, rather than bolted to the spider, as with modern cranks. I'm keeping the rim, so I'll need to find a 36-hole hub (as opposed to the more popular 32h nowadays) and a new set of spokes.

I'm going to remove the rack, water bottle cage, shifters and shift cables, but I will keep the brakes for the time being, despite of it frowned upon by some "hardcore" fixie riders. I may (probably will) remove them eventually.

I would like to do as much work as I can to keep costs down, and because I enjoy working on projects. I may need to go to a bike shop to pull the cranks, but I've read about some other makeshift tools for a lot of the work. More on that later.

So far, here's the procedure:
  1. Go to bike shop for quotes on parts and work
  2. Go to powder coating shop for quote on paint job
  3. Disassemble bike
    1. Remove rack
    2. Remove water bottle cage
    3. Remove brake levers, shifters and cables
    4. Remove brakes
    5. Remove kickstand
    6. Remove wheels
    7. Remove derailer
    8. Remove chain
    9. Pull cranks
    10. Remove bottom bracket
    11. Remove seatpost and saddle
    12. Remove handlebar stem and handlebars
    13. Disassemble headset and remove fork
    14. Pull head tube and fork crown races
    15. Drill out head badge rivets and remove badge
  4. Strip paint from frame
    1. Apply paint stripper and scrape paint
    2. Remove paint from crevices with a wire brush wheel on a rotary tool
    3. Wipe down entire frame with solvent/cleaner
  5. Bring frame for powder coating
  6. Order parts
  7. Clean remaining parts
    1. Clean off dirt, grease and rust then regrease
    2. Overhaul headset, bottom bracket, front hub
      1. Replace bearings
      2. Grease
  8. Assemble bike
    1. Build back wheel
    2. Etc.
