Help: How to remove early Rotor drive side crank

The usual crank puller worked fine on the non-drive side. I have no idea how to remove the drive side.

You could try removing the two bolts of the extra arms on the crank and check if the crankarm pulls off or unscrews from the BB axle. Just taking a wild guess.

You've probably read this already, but I'm emphasizing the parts that might be relevant. It almost sounds like you have to take the bottom bracket out entirely, and the drive side crank comes with it (??)

"The Rotor comes with its own bottom bracket assembly and the right hand crank and linkages are attached to this out of the box. Fitting involves locking out the linkages with the supplied bolt and threading the whole shooting match in to the bottom bracket shell. Not forgetting to mount the inner chainring, of course. Youíll have to do a bit of measuring to get the chainline right, and the actual orientation of the BB in the shell is important Ė get it wrong and the cranksíll be articulating in the wrong places. The final steps are putting the lockring on the non-drive side, mounting the left-hand crank (itís a regular square-taper item) and mounting the chainrings. The instructions are reasonably clear, and itís not difficult. Donít expect to chuck íem in and go straight out for a ride, though Ė the system relies on Loctite to keep the BB in the right position so you need to allow a few hours for it to set."

^^^^Great find Rolla. Interesting design to alter the chainrings. I can't decide if that's brilliant or a Rube Goldberg award candidate or both.
