Shimano BB-7400, what cranks will fit?

To HAJ

You have a Kerein frame? Sounds very Hi end track. anyhow, the 7400 taper BB is the late 80's Dura Ace BB, for the DA double cranks, 112mm spindle for english BB shell.If you mount the spindle with the shorter end on the drive side, it should approximate a 110mm bb.The taper is JIS, or the shimano workhorse standard, not the NJS, which is 7600 DA track, or Sugino 75.
  There are less snobbish JIS Taper cranks on ebay, that should work with a 110mm spindle, or you could get an old shimano 600 ex crank from the mid 80's, that could do for now, unless youre up against Chris Hoy, in an elite track meet.
                                                            Good luck
