Open Question Putting cranks on a shimano un55? On the drive side spindle of a shimano un55 theres like a flat round platform bit at the end of the taper, like it tapers up to it, do i snug the crank up against this? The inside of my crank is literally 1mm away from it but its perfect torque as it is, do i go that little bit further? The other side doesnt have it though its just the square taper until it gets to a wider ramp on each side that would clearly damage the square hole if it went too tight, i dont know how far to go, if it would add any stability to have the crank flush with the round flat bit or not?
