SHIMANO Ultegra crankset 2x FC-R8100-P | Power Meter
The Ultegra FC-R8100-P crank not only converts your pedal power into propulsion, with its high rigidity it also ensures extremely fast and precise shifting. The high shifting precision is supported by the optimized chainring design.In order to keep the weight low, the Japanese continue to rely on the proven Hollowtech II design of the crank arms. A large selection of crank arm lengths and chainring options ensures that the right crank is available for every type of rider and every terrain.
The new integrated power meter processes the data with outstanding accuracy. With one sensor each on the left and right crank arm, you can also detect muscular imbalances between the legs in addition to power evaluation. The waterproof construction provides reliable and precise data in all conditions. This is also ensured by the software's active temperature compensation. 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 maximum 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 the need for removal.
