    BB30 or PF30 for singlespeed frame?

    So I found a big gouge in my Forks, and my Scandal frame is badly corroded, so its time for a new frame and forks, but I don't have much $$$ to spend.

    I'll pick up some used forks, but am looking at a chinese carbon frame and will get an EBB for it.

    My question is, is there any advantage in getting either BB30 or PF30?

    Thinking PF30 may give me more options, and the bigger diameter may give a better contact area to reduce slippage and creaking.

    You'll have to be careful putting an EBB in a carbon frame that wasn't specifically made for it. I would lean towards the BB30 because it should have an aluminum be shell bonded in the carbon. This will give the EBB something to tighten down against. The PF30 frame probably will just be moulded carbon, which...may or may not be able to handle the clamping forces from the EBB.

    Good point, I've mailed the company to see if the PF30 has an aluminium sleeve.

    There was a guy on here that put a Wheels EBB in his Specialized carbon frame... search for threads about the Wheels EBB and you should be able to find it. Personally I would go PF30 if at all possible, there are a ton of options for that shell.

    Yeh I saw that. Looks good.

    I went with a PF30, because that's what the supplier recommended. He also said the PF30 did have an aluminum sleeve.

    I also ordered an Origin8 EBB as I'm on a bit of a budget, and hadn't intended to replace my SS frame until I noticed my damaged forks last week. Hopefully I can get it to work OK.
