The bottom bracket where 3 frame arms meet is supplied with ball or roller bearings which are able to reduce friction very substantially. There are ball or roller bearings also in the gear changing mechanism, in the top and bottom of the "headstock", the front tube into which the handlebar fits, in the pedals, and in the hubs of both wheels.

What size is your haro f1 09 bottom bracket?
A Haro F1 uses a "standard USA" bottom bracket with press-in cups (as opposed to a "Euro" bottom bracket, like what road and MTB bikes use). These bottom brackets don't come in sizes because there's only one size. Bottom bracket spindles do, however, vary based on the crankset you're using. If you're talking about the Haro Fusion cranks that come with that bike, you're talking about a 19MM, 8 spline spindle, which is actually pretty standard.

Installing a mid bottom bracket is very simple. All you do is tap both bearings into both side of the frame evenly, they do not have threads or anything like that its just simple pressure, don't hit it to hard though because you could crush the bearings.
