Hi,
Am i right in thinking that Ultegra 6600,6700, 6800 are all the same size and will fit my 5700 chainset

    To add on to that question;

    I have 10 speed, English, 105 BB's on both bikes, but am finding it impossible to source any new ones! (Without resorting to ebay.)
    So, are all the hollowtech II BB's through out the range interchangeable?
    Will the newer 11 speed 105's still fit? (Not that I can find any of those either.)

    Does anyone have any theories as to why they are now so scarce?

    Cheers.

    Because they have been replaced by the newer, smaller diameter 5800 / 6800 series BB's?. They all still accommodate the 24mm axle, so they are interchangeable. You just need a smaller tool or a plastic adapter with an old tool to install / remove the newer ones.

    The ultegra 6800 BB at CRC is amazing value at this time
