Mike, Jerry is right. I have a left crank arm that is so close to the adjustable cup that you can't even fit a flat head screw driver in there. As long as you are not rubbing you will be fine. A Phil Wood 119mm with the normal taper will work just fine. I use one myself. Lateral positioning is adjustable as well. The Phil people are great with customer service, even if you call. Other manufacturers could stand a few lessons from the "Philgroup".
