    Shimano crankset BB compatibility

    I am planning to replace my FSA cranks with Shimano 5750 compact crankset.

    In terms of the bottom bracket, does it matter if I use a Shimano 105, Ultegra or Dura Ace BB? Or is there something special about the 105 crank that requires a 105 BB ?

    Thanks,

    G.

    I am almost positive you can use any Shimano bottom bracket thatwill fit your frame.

    What is the difference between the Mtn and Road Hollowtech II BB? Can you use a Shimano mtn crank with a road BB?

    the threaded section is longer on the mtb cups so you can use the spacers on 68mm bb shells. not sure if there is any other difference.
