Help me remove Shimano Selecta BB cups...
I have an old twelve speed with the horizontal drops that I was trying to make rideable. The bike is a Sekine Milennia, circa ~1980. The left crank was loose and destroyed and after I removed it I noticed the eight spline shaft. I removed the arms, shaft, rings, but there doesn't seem to be any female part for a tool to mate to?
Is a pipe wrench the way to go?
Any idea if this bike would be English or Japanese threaded?
Thanks for any advice you may offer.
