I have a Dura ace (10 speed) chainset on one of my bikes and a Bontrager compact on another.
the bottom bracket bearings are mounted outside. Does anyone know if these are the same type, i.e. could I take the Dura ace chain set and put it onto the bike leaving the bontrager bottom bracket in place??

The FSA ones are certainly interchangeable with Shimano - depends who makes the Bontranger chainset, but if you try it, it fits snugly and doesn't waggle about, then why not.
