Shimano Dura-Ace R9200-P 12 Spd Road Power Meter Crankset
The Dura-Ace FC-R9200-P crank not only converts your pedaling power into propulsion, with its high rigidity it also ensures extremely fast and precise switching behavior. In order to keep the weight low, the Japanese continue to rely on the proven Hollowtech II construction of the crank arms. A large selection of crank arm lengths and chainring options ensures the availability of the right crank for every type of rider and every terrain.
The new integrated power meter processes the data with outstanding accuracy. With a sensor on each of the left and right crank arms, you can identify muscular imbalances between the legs in addition to performance evaluation. The waterproof construction provides reliable and precise data under all conditions. This is also ensured by the software's active temperature compensation. A manual zero point calibration can be carried out in next to no time using a switch on the transmitter. Strain gauges developed by Shimano are used for the greatest possible accuracy. The internal lithium-ion battery supplies the power meter with power for up to 300 operating hours and is charged via an integrated port without removing it
