Specialized s-works oversized bottom bracket options

[David Lowther]

Hi,

I just bought a used specialized s-works tarmac frame (2007 model I think)
with what looks like an oversized bottom bracket shell.

I have a pair of campagnolo neutron wheels which I would like to use with
the frame.

I'm wondering whether it's going to be possible to fit a compact campagnolo
crankset.

Can anyone tell me what options I have for bottom bracket choice, e.g.

Do I have to buy a specialized bottom bracket, or are compatible parts
available from other manufacturers (+ info) ?

TIA

Dave.

One more try at posting a link to a photo of the bottom bracket shell (last
message was removed from server - maybe because I posted a link to a jpg ?)

Is this one of the frames using Cannondale's BB30 standard?

I can't see where the 30mm comes from...

Uh, it measures on your scale from 48mm to 83mm, or a 35mm diameter.
That's most likely a standard BSC (34.8mm) threaded BB. Get any standard
Campagnolo crank with matching BSC BB or cup set.

I don't think so, I had a look at the bb30 pdf drawing.

The frame is threaded on both sides, which with a few hints now look to be
standard (37 mm?) BB fittings.

Best Regards

Dave.

Then it might be standard English threaded: 1.37 x 24 tpi

Probably yes, standard BSC 34.8mm; usually described as 1.370 inches
with a reversed thread on the chain side.
