I picked up a sweet CAAD6 on eBay last night (unsure of year but it is a Stars and Stripes Saeco version) and in my post-bid stupor I realized that I am unsure if the BB on the bike is BB30 or is the English standard. I've been attempting to do research all morning (instead of actually working) and am fairly certain that CAAD6 frame was part of the SI generation and only comes with the BB30 option.
I can't tell from the pics from the post (attached) which type of BB it is, but if you can that would be greatly appreciated.
Does anyone know if this is certain, that every CAAD6 is a BB30?
If so I will be extremely bitter and will have to hunt down one of those adapters because I already have a full Ultegra group ready to go for this frame and don't want to spend even more money on the BB and the SI crank which are hard to find on the cheap. I would also have to pray that when it arrives the BB is in good shape and can handle the adapter, or else I basically have to junk the frame and go into Paypal arbitration to get my money back.
