Alright, so I'm fed up with the low ass bb height on my '08 p.2, and realized that I could get an azonic steelhead frame for less than i could sell my p.2 frame for. This idea was perfect, until I found a difference in specs between my p.2 and the steelhead.
The bb on my bike is 73mm, and the bb on the bike i want is 68mm. :madman:
So thats all good right? I start looking on pricepoint (where i'm getting the steelhead and a single speed kit) and find a few cheap bottom brackets. I look at the sizing, and on every one i see that they have the threads for both 68 and 73 in one size.
So to end my story, I'm wondering if it's safe to assume that the bottom bracket currently on my p.2 ("Fuse Euro") has the threads for a 68mm frame?
I am downgrading though, from a 73 to a 68, why would i need a spacer? This doesn't make sense to me although thanks for the help. I'm going to pull the trigger on the frame.

You will need spacers because the spindle for your crankset is designed for a 73mm shell width. By adding 2-2.5mm (5mm total) spacers you effectively widen the 68mm shell to 73mm. This way a manufacturer can kill 2 birds with one stone by designing the crankset for 73mm.
You don't say if you have a 2 piece crank or a 3 piece Shimano Octalink or Isis 3 piece crank.
It doesn't really matter unless you are buying a new BB and then it only matters if you have a 3 piece crankset.

I needed a larger frame and a higher bb height. If the steelhead doesn't work out I'll sell it and stick with the p.2, I'm going to try to keep an unbiased opinion when comparing the two.
The P2 is lighter and why the higher BB height? for DJ use and Park riding a lower BB height is better. Plus going from a 73 to a 68 is not a downgrade it is just to accomadet different bike geometery in the frame both sizes have the advantages.
A lower BB is not necessarily better for DJ/Park/Street. Higher BB gives more pop. A lower BB would give more snap leaving a gate if you're into slalom-y stuff.
Guys. Just clarifying here, I bought a used steelhead and building it up. Now are all year steelhead BB's 68mm? And 68mm by what? 110...115...i really don't know?
