Hey ya'll,
i'm currently a first time builder (to be), and I'm having a bit of trouble comprehending just about everything. I'm reading the Paterek Manual, I've looked through Sheldon Brown's site, and talked to various people. I've still got heaps of questions!

One that's getting me is that head tube size. I'm looking to make a single speed as my first build for simplicity sake. I'd like to have a 1 1/8" head tube. What size head tube should I be looking at purchasing? Various options include 31.7mm, 36mm, 46.4mm, etc. Sheldon Brown said that 1 1/8 is a 28.6, so is this the true size that I'll be looking for? If so, I guess I'm a bit out of luck at the moment with buying one that works for me!

Thanks,
Gavin
