    removing si bb adapter??

    looking through a number of threads related to si cranks and bb 30 etc. i just wanted to clear it up in my own mind if it is a viable option to remove the factory fitted bottom bracket adapter (for standard 68mm) on a taurine. as i understand it, you cannot remove the adaptor from the synapse crabon frame. if this topic has been covered then i'm sorry!

    many thanks,

    According to Cannondale it is not OK to remove the adapters from any frame. That said, it does happen often. I am currently riding a system six that had the adapter removed and have had no problems with it.

    I thought it was not recommended but doable on alloy BB shells (like the System Six) but a big no no on carbon BB shell (like on the Taurine)...

    Cannondale does make a tool for the adaptor removal. They say that repeated removal and reinsertion may damage an alloy frame (ie. dont do it too often) but it should not be attempted on a carbon frame.
    I have removed and reinserted an adaptor on a Scalpel frame and a CAAD8 road frame without any incident. I have heard of people removing them on Synapse, Taurine and Carbon Rush frames, but wouldnt be game to try it myself (unless it wasnt my frame and there were no consequences to damaging said frame.......)

    The guys from my local Cdale dealer removed the adapter from my carbon Rize (Two) w/o any problems. They have done it in several bikes but never more than once as the carbon bottom bracket could be damaged. So, I suggest you not to do it yourself unless you're a real pro mech! Talk to your Cdale dealer and ask them to do it for you, but remember to discuss first if the warranty would be voided. Good luck

    I have a Caffeine F-4, and I take it that if I were do this switch, I too would have to remove the BB adapter? Also, what is the advantage to going with a BB30? Costs involved? Please advise, I'm just getting back into cycling after a 15 year hiatus! Thanks in advance!

    The F4 has a standard bottom bracket shell, not a BB30 with an adaptor pressed in so you cant run a BB30. Its only the Taurine, Carbon Rush, Rize, Scalpel Carbon and Moto frames that come BB 30, although all but one Euro Moto models have an adaptor pressed in.
    Regarding removing it from a carbon frame, it comes down to how the aluminium bottom bracket shell is placed in the frame. If the removal tool can be placed straight on the aluminium of the shell, then you can press an adaptor out of a carbon frame, but if you have to place it on carbon that surrounds the shell then you will damage the frame. I have successfully removed the adaptor on a Cannondale Slice Carbon frame without any issues despite Cannondales warnings to the contrary, but if you dont know what you are doing you could easily cause damage.

    for reference, the scalpel, and rize are considered aluminum frames (as far as BB shell is concerned)

    Rush and taurine the insert is not supposed to be removed.
