|Derailleur Cage Belt Loop|
Great for hanging your keys or your wrench.
This is the part that tightens a grip shift to the handlebars. It turns out that handlebars are the same size as my index finger!
|Brake Lever Plugs|
Old-timey brake levers have a nice ball at the end, and chopping one down makes a great plug. I reckon it's a little bit bigger than an ought gauge. Then you can stretch up to a kickstand!
|Inner Tube Rings|
Cut 'em small for traditional rings, or use the part with the valve for a nice spiky look.
The tricky part about wearing chains is not the gauge of the barrel, but the width of your lobe. Motorcycle chain might work. I had to go all the way up to industrial chain. Use the quick-release link if you can, or put it in with a chain tool.
