What size bottom bracket do I need to order. 68x108 or 68x113. I've noticed during my reading that it's a mix of what people are using. Not doing gears at this time. Also what headsets do you recommend. Don't like the stock ones.

Ordered sinz 120 cranks and 34 t chain ring. I'm adding 20in forks and a low rise bar. Also found a crupi seat that I need to pick up.
