Good day sir/ma'am!
I just want to ask if my FSA RPM 68mm bottom bracket is compatible with a 105 5800 crankset?
If not, what bottom bracket should I have?
My frame is a Giant Defy 5 2015. Thanks in advance! :D

    That's a square taper bottom bracket? If so, no. A square taper crankset has two separate cranks that are attached to the bottom bracket.

    The 105 5800 has a shaft as an integral part of one crank, this goes all the way through the bottom bracket and the other crank arm attaches to it. The system is called hollowtech.

    Shimano bottom brackets are very cheap anyway.
