More parts! The UPS man made it through on a snowy, ice day. Here's the chain ring, chain, and cranks. These are BMX parts. Not road parts. But since I'm building a single track bike (meaning the chain will never shift--in common with but not to be confused with a fixed gear or single speed bike), it's better.
I like the square pattern in which the chain comes out of the package. It looks like the solution to a puzzel. I bet if I straighten it out I'd never be able to make it a perfect square again.
