Hey guys! In the last couple days I was thinking of buying a Profile Z Coaster but when I go to their site I have to build up the Rear Hub myself and to be honest I don't really understand what is going on and what should I set as an option for the Axle, the Bold Option, etc. So if somebody here has a Z Coaster could you guys please help me out and tell me what everything means and what options should I choose? Thanks in advance. And yes I am a beginner.
