Spindle Powermeter

Crankshaft measuring system - the latest option for powermeter

Rotor was the pioneer of this new generation of power meters and meanwhile, more manufacturers are following. The strain gauge placed in the crank axis (actually the crankshaft) would be the optimal place, since the time when there are hollow crankshafts, this place is by the bicycle. Another advantage is the completely hidden, protected system and the accuracy of this variation of performance measurement. Since the forces are removed there (apart from possible torsional forces) where you are very precisely and immediately for both sides, these crankshafts performance knives are certainly a sensible alternative.
