How To Build Your Own Bicycle
2
The Frame
Sometimes the classifieds or your local co-op are
good places to start looking for frames. You need
to make a choice on what kind of bike you want to
build and buy accordingly. You should look for
something your size of course and judging against
the past bikes youve owned this should be
relatively easy.

The Fork
You should know what material is best for how you
want to ride and it needs to have the right
clearance for the types of tires you want. Some
manufacturers are now doing offset or tapered
headsets in which the top race is smaller in
outside diameter than the bottom race.

The Headset
Briefly mentioned before, the headset is a set of
bearings, cups, and races that connects the fork
to the frame. It is what allows your front wheel
to turn. The races are pressed down onto the
fork, the cups are placed into the holes in the
head tube on the frame, and bearings fit into
these cups.
5
The Stem
Sizing and compatibility are also very important
here. You need to get a stem that will fit around
your steer tube. Modern stems fit down over the
steer tube and tighten into place. Often times
there will be spacers to raise the height of the
stem. The spacers go on top of the headset and
then the stem fits down over them.
6
The Quill Stem
A quill stem is an older part from a time when
forks and headsets were threaded so owners could
remove the play in the fork by tightening down
then nuts over spacers down onto the fork itself.
Then the quill stem would actually fit down
inside the steer tube instead of down over the
steer tube like a modern stem.

The Brakes

• There are 3 types of brakes out there.
• Hub brakes where the braking mechanism is in the
  hub like drum brakes or coaster brakes.
• Disc Brakes which use a disc rotor and hydraulic
  or mechanical calipers.
• Rim brakes which use a caliper to squeeze the
  braking surface of your rims.

Wheels and Tires
Wheels are made up of a hub, a rim, spokes, and
nipples. Hubs and their quality will determine
how light your wheel is and well it will roll.
Inside the hub is a set of bearings sitting over
your axle. The better the bearings the better it
rolls.

The Seat Post
 First of all, make sure you get the right size
that is compatible with your seat tube on your
frame. After that it is a matter of the material.

The Saddle
The saddle is perhaps the easiest thing to buy
that will affect the way you ride. Get something
comfortable that you can put some miles. Dont
worry about compatibility so much because all
saddles interface with the post the same way and
sizing is not an issue.
