Im contemplating building my own bike from scratch, and it would be my first time doing so. Yes yes i know i know its more expensive, ive read all those threads.
And yes it very easily can be. and i accept that, but the value of knowing how to assemble an entire bike is very appealing. And i know what I want, and what I can get away with in terms of parts and gear.

I have various tools at the house, but not many bicycle specific tools.

So please teach me bike tools.

What BB tools will I need? How do I choose out the right one? The frame i'm looking at uses 68mm BB, there are many types and kinds of bottom brackets and a specific tool for each, am I right?

What about the headset? Ive read some DIY ways of installing headsets. This part of the build worries me the most.

Then i need a chain tool, thats straight forward.

Everything else I can take care of with basic tools.

Am I missing anything?
