Shimano Dura-Ace R9100-P Crankset
The Shimano Dura Ace 9100 has been a reliable crankset since succeeding its predecessor. Now with the power meter version, it guarantees reliability and boasts a completely sealed, crank-integrated design that is waterproof in all condition.
There is also a small magnetic adapter that allows the battery to be recharge by not opening any cover at all. By having a direct instant response system, it ensures an accurate data collection for stable power measurement at various stepping positions. A very nice simple reset switch at the transmitter allows easy reset.
