Before I purchased the On-One Pickenflick one of the numerous questions I asked the Planet-x customer representative was whether my old Rotor 3d+ crankset would fit. The answer from their “technical team” was that it was going to be a no go. On the forums there have been some talk of revisions to the frame geometry and I really would like to use the power meter chainset so I thought I would give it a try.
Bottom bracket shell on the Pickenflick is 68mm just like my previous RT-90 had. As you can see in the picture theonly challenge could lie in fitting the chainrings around the chainstays. Unless the chainstays flex awfully lot it should not really become a problem if you use a fairly small chainring (eg. 34t) or single narrow-wide chainring setup in the outer position.
The only lesson from this exercise is that the crank fits fine and Planet-x staff do not know what they are talking about.
