Power meters have come a long way, and the the Quarq ELSA 10R Power Meter Crankset is the culmination of years of tweaking. Featuring Omnical, which allows you to change your chainrings without having to recalibrate your power meter, the ELSA gives you the option to ride any wheels and any size chainrings, while still getting power numbers that are accurate to +/- 1.5%. Another great improvement is that the battery is now easy to find and can be easily replaced without having to send your cranks in. With lightweight Exogram Hollow Carbon crank arms and Power Balance to capture left and right drive strokes individually, the Quarq ELSA 10R Power Meter is the height of power meter technology.
