Want to run sealed bearing's in my old school frame's bottom bracket and still use my old 3 pce Takigi tourney cranks.The bb is the standand US size,is there a conversion kit available to do this.

The Takagi crank that you have is a square taper fitting, is that correct? If so, there are a few that are out there. MCS makes a sealed conversion BB that should work with it.
