im thinking of changing my sora triple 9speed 3403 chainset, for an ultegra 6703 triple chainset 10 speed on my trek 1.5 my bottom bracket at the moment is a tigra 4600, but the ultegra uses a ultegra bottom bracket, what is the difference between them, they are both 68mm english thread.

    Cost, bearing quality e.t.c. Otherwise they are interchangeable.

    If your existing chainset needs replacing and the Ultegra is a good price then sure.

    But if you are just replacing it hoping it will make a massive difference to your cycling then forget it.

    It is 3 grades up the shimano range (and ony DA is higher) so it will be better - just not 5 mins off your PB better.
    Yellow is the new Black.
