    AFAIK any Shimano Hollowtech crankset will fit, its 24mm diameter I think.

    if the current crank is a shimano 105 chainsets its a hollowtech 2 bb, all modern shimano chainsets are hollowtech 2

    You have a hollowtech 2 bottom bracket...Any of the newer ones like shimano 105-5700 Shimano ultegra-6700 Or even Dura ace-7900 are compatible with your chainset as they all use a 24mm diameter bottom bracket axle..
