Hopefully, this should be an easy one for the local experts. Basically, I picked up an old steel road bike. The fit and geometry work pretty well, but a lot of components need updating. I'm thinking I can keep it as a beater / backup bike until it falls apart.
What I'd like to do is figure out the geometry of it, in order to compare to other bikes. Any idea on how to properly figure this out? Most specs are pretty easy (e.g. chainstay, wheelbase). The main things I'm stuck on are seat tube angle, head tube angle, and fork specs like rake / trail.
