>>1903250You need to check on the existing BB shell. If you have a cartridge unit chances are you need picrel. If its an old adjustable cone type you need a pin spanner. If its newer and has external cups you can be faced with a wide variety of standards but I doubt you have one of those BBs and a square taper.
The hollowtech meme might very well have external cups and the special tool you need very much depends on the brand. If you want to torque it to spec get the correct socket. If you dont care just get one of the chinesium multi spline wrenches with corresponding adapters. Those cover most if not all the external hollowmeme stuff. I'll post a pic of the feels right torque stuff too.
