Right, but right now I'm thinking about how to pull the crankarm off without destroying it if I need to ship it off somewhere. I'm thinking about using a ball joint fork or perhaps an adjustable 3 arm harmonic balancer puller.
I use a light layer of phil grease on the taper before installation; I also lightly greased the puller. It yanked the threads out from the very bottom, so if you feel the inside of the arm where the extraction threads are, it's totally smooth.
Completely understandable that there's some skeptics out there, but I've removed and installed dozens of SqT cranks in my days. Again, I was surprised by how easily the things let loose. It was like pulling a cork out of a wine bottle.
Pedalling, let me know if you want to sell your set. Unfortunately I don't have any other spare square tapers lying around to fit an ISO, let alone any in black.
