Tester, do these cranks go some way towards resolving your criticisms about power meters failing to measure all the different forces applied to a crank (twisting, bending etc.)
No, because my criticism was specifically that Stages would have to measure all axes of deflection and then apply an appropriate algorithm to determine true tangential force. As Axis points out, others measure the torque between the crankshaft and drive gear (SRM, Quarq, P2M) or between the driven gear and wheel hub (Powertap), taking the crank itself out of the equation. Vector and KeoPower have the potential to measure all axes of pedal applied load to provide the same kind of analysis as Axis is trumpeting, but I'm not sure that they currently do.
As a pedalling analysis tool, Axis looks interesting, but I'm not sure how much use anybody could make of the information outside of a bike fitting/R&D/rehabilitation context - by the time your pedalling form has gone all to fuck, your ability to do anything about it has probably gone out of the window too.
