As Shimano released their newest version of their top-quality Road groupset, they did so with a power meter option. In the past, they have left the power meter market for the competition, but that has changed with the Dura Ace FC9100-P crankset.
From the outside, the new crankset looks very similar to the normal version. However, when taking a closer look, one notices the charging port with LED on the drive side and the strain gauges on the non-drive side crankarm. Looking even closer, you will notice that there is a magnet mounted to the frame, which is responsible for helping track cadence. The magnet cover is available in black and white so that it can match almost every bike frame.
