I'm converting my CAAD10 to use a BS68mm Shimano chainset. I've just taken delivery of the FSA adapter but it didn't come with any glue.

Can't find anything on the FSA tech docs. IIRC it's Loctite 609 but I'm not 100%. Any ideas?

Thanks in advance.

    Any particular reason why you wouldn't use it? Seeing as I'm about to undertake a quite difficult to reverse process, I'm really interested.

    I'm on my third set of bearings in less than 600 dry, race only miles and I don't want to swap the issues I've had with BB30 for another headache.

    I bought the genuine Cannondale adapter. It came with loctite 609 and 2 cups to press in with. The FSA one is identical.
    I can't work out why someone would fit anything else ?

    Have done this conversion myself last year. The FSA adapter I got came with a little tube of Loctite 609. Absolutely no problems with it since.

    Cannondale apparently void their frame warranty if you remove the press-in adaptor at a later date. Agree that the KCNC or Praxis adaptors are a better way to deal with the problem as the bearing alignment is guaranteed.

    Cannondale say you can remove their adapter from Alloy frames but it's not advisable from carbon.

    From an engineering purists point of view the KCNC adapter looks a bit bellow par. Your turning both ends of the adapter which have rubber rubber O-rings on the friction surface. Some photos here:

    It cannot be as tight as the expanding praxis design or a tight tube requiring a press to fit.

    Thanks! :D

    I do like the look of the KCNC adapter. I hadn't seen that before, just the usual suspects from Praxis/SRAM/Wheels Mfg. It appears expensive in comparison to the FSA sleeve but then when you factor in I needed to buy the BB cups and will now need glue it makes a bit more sense...

    Will have to have a think about it. Has anyone on here actually installed/used the KCNC offering??

    Installed a KCNC BB on a friend's bike - no problems - it's a tube with a couple of bearings press-fitted either end and doesn't need to be overly-tight fit into the frame.
