Would an Ultegra 6700 BB work with a 105 5600 crankset. For some reason the Ultegra BB is cheaper than the 105 one on CRC...

    At least all road ones are interchangeable. I'm not sure about MTB, but I think they are wider/with spacers.

    WRT the road ones, does anyone actually know if there are any differences between Sora / Tiagra / 105 / Ultegra / DuraAce apart from the colour of the alloy cups?? Anybody weighed the things or dismantled a broken one to see the innards??

    for £10 more, why not just get the Dura-ace one?

    Yes they do weigh a few grams less as you go up the range, the bearings themselves are different as well as the seals. Basically parts get more durable and lighter as you go up the range.

    IIRC you also get a better warranty on the higher range stuff. 2 years for Ultegra and 3 years for DA.
