My winter bike is a Merlin with pressed in Campy Spindle. the left arm got damaged and would like to simply replace with a Suntour or Sugino that is available. How close is the JIL to the ISO Tapers?
What he said. Angle of the tapers is the same, but the width is different.
Yes, but that's the "no problem" way because the crank is further out on the taper. OP has the opposite "there may be a problem" way where he could run out of taper or run into interference.i've mixed jis and iso a couple times without issue.
i just rebuilt my paramount with a jis spindle and vintage campy crank. it works great
