That's interesting... I read on Shimano's website in their product specs that the unit includes a bottom bracket (integrated). Then when I was looking at buying it on a few online sites, several mentioned 'does not include bottom bracket'. Well I checked again, the Shimano site said it did. I phoned up my LBS and asked them how much etc and asked them whether we'd also need to buy a bottom bracket. He checked and said it was included. So now I'm totally confused.

Would you happen to know if the unit you installed was a R700? As far as I can see they only do one, which is fine for both Ultegra and DuraAce.

My bike is totally DuraAce groupset. I was hoping that if it the compact unit doesn't include the bottom bracket, then the bb I have on the bike - a Hollowtech II double crank - will hopefully work perfectly fine on the Hollowtech II compact crank. Is this unrealistic?

Did you have to replace the chain because the bike was 9sp? or is that something that would need to be done regardless.

Thanks....
