Nicolas,
First off, thanks for the quick reply. Thanks for the recommendation too.
I will be going for the 130bcd/classic and possibly switching between my Osymetric and standard rings occasionally. My crankset comes off anytime I need to switch out pads (BMC Time Machine), so that’s not a new process. I’m not sure how having the spider removal tool would be useful for taking the cranks off and on. Wouldn’t the PM/spider stay put unless I wanted to put it on a different 3d+? Please don’t take this as me disagreeing with you, I was just curious if there is something I’m missing here.
