A little while back I decided I wanted a Fixie/ single speed bike to see what all the fuss was about. I also wanted a better workout while riding, and couldn't exhibit self control on a normal bike by using only one gear.
Really awesome article about the culture, history, proper riding techniques, and dangers of fixies by Sheldon: http://sheldonbrown.com/fixed.html
But of course I couldn't just buy one; we all know it is much more rewarding and OG to build it yourself!
For this project, I used an old Univega bike frame from the 1970's. I really like the character and craftsmanship of older bike frames.

Step 1: Supplies and Parts
The parts you will need will depend on your build, but this is a general list to consider:
- 1 bike frame and fork
- 2 wheels ( I got mine from Amazon.com, purefix single speed wheels 50mm, flip flop)
- 2 tires (700 x 25)
- 2 inner tubes (700 x 25)
- 2 brake sets with cables (Or just one; purefix.com)
- 1 single speed crankset (Amazon)
- 2 pedals (Amazon)
- 2 cages and straps (Optional, but very helpful when riding a single speed/ fixie)
- 1 saddle (Amazon)
- 1 seatpost (Amazon)
- 1 stem (Amazon)
- 1 bottom bracket (If needed, amazon)
- 1 single speed chain (Amazon)
- 1 handlebar (Mine are drop bars, purefix.com)
- handlebar tape(Optional, purefix.com or Amazon)
- sandblaster with sand (Optional)
- paint stripper (Optional, hardware store)
- powder coating kit (Optional, amazon)
* Important: Make sure your frame has "horizontal dropouts", which means the slots that hold your rear wheel axle are more or less in a horizontal plane. This allows for forward and backward movement of the wheel to adjust for chain tension, which is necessary to prevent your chain from slipping off. Alternatively, there is now a special hub you can buy if your frame has "vertical dropouts" . This hub allows for some horizontal adjustments for chain tensioning (http://sheldonbrown.com/harris/white-hubs.html)
When working with an old frame, you may inevitably run into sizing problems when trying to put new parts on. As with any bike related problem, sheldon brown is the go-to source. (http://sheldonbrown.com/fixed/index.html)
