I had the same issue, spoke to Evans and it was a mistake on the website (Q&A) however they agreed to supply some FOC. I still had to buy a kit because I was using a used chainset I need the circlips, spacers, cover washers and wavy washer...so now have a spare set!
@Dick / @swedeee did your CAAD 10s come with BB30 bearings?
Just getting round to putting mine together and nothing in the box, but the website said it would come with some?
