I have both an Origin with aluminum crank arms and an Origin with carbon (Look) crank arms.
It was quite straight forward to remove the drive-side aluminum crank arm, but I haven't been able to get the carbon crank arm to move away from the spider.
While SRM offers crank arm swap services, I feel that this should be something one should be able to do with the right tools, especially I was able to remove the aluminum arms from an Origin spider.
Has anyone had success in removing the carbon DS arm? If so, how did you do it? I probably won't want to resorting to using vices and such, as I wouldn't want to damage the carbon from clamping.

It is like the NDS. But SRM makes a tool/screw in order to bend up the crank a little. I could remove my crank arms without the tool. You can see it here, last post the red screw.

Danke schön!
I must have read that thread front-to-end twice, but I didn't realize how relevant that post was to my situation.
And SRM doesn't even list that tool on its webpage. Would have been very helpful as I could have bought it weeks ago and had it shipped with my other items.
