    Triple to Compact Double crankset questions

    I am converting my 2006 Specialized Roubaix from a Campagnolo Mirage triple crankset with a Phil Wood BB to a compact double crankset. I believe the BB size for my bike is 68mm. So my question is could I switch to a Campagnolo Centaur CT Power-Torque Crankset (50/34). I know I have to change my BB and was wondering what kind of BB I would need for my desired double crankset swap?

    You'll just need the newer, external Campagnolo bb cups. Fortunately they are cheaper than the square taper variety because they are just cups - the bearings are pressed on the crank spindle. Also make sure you get the english threading rather than italian.

    Ok great thank you. And this external BB would fit on a aluminum frame from 2006?

    I'd get the frame chased and faced too before fitting the newer type BB. It ensures the faces of the BB shell are parallel and gives the bearings the best chance of a longer life. A good LBS wont charge much for this but its essential to have the right tools.
