#16) Bike Chains
- The crank to drive-wheel link.
The Chain folds around and through both
the crank and the rear cog set and is able to ramp
up and down the different gear combinations depending
on your present speed. Chains come in varying widths,
like fat for single speed (usually fatter style chain
rings have longer life and better strength), or super
narrow (to squeeze between up to ten tightly spaced
cogs like on a road bike). There is a super fat BMX
chain out now that would make great jewelry too.
