Shimano's new 12-speed road groupset delivers unparalleled control and comfort anytime, anywhere - whether you're competing in an amateur race, chasing your personal best, or out for a social ride. That is \"Science of Speed\".

The dual-sided measurement accuracy is down to 2.0% and calibration is quickly and easily done. And what is perhaps most important: the long battery lifespan, simple rechargeability and connectivity with ANT+ and Bluetooth LE make it child's play to use it and assess your workouts.\u003c\/div\u003e\n\u003cdiv class=\"product--description\" itemprop=\"description\"\u003e\u003c\/div\u003e\n\u003ch3 class=\"product--description\" itemprop=\"description\"\u003eFeatures of 50\/34 and 52\/36\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIntegrated design\u003c\/li\u003e\n\u003cli\u003eReliable electric system\u003c\/li\u003e\n\u003cli\u003eWaterproof in all conditions\u003c\/li\u003e\n\u003cli\u003eEasy maintenance\u003c\/li\u003e\n\u003cli\u003eIntegrated rechargeable battery\u003c\/li\u003e\n\u003cli\u003eBattery charged for less trouble\u003c\/li\u003e\n\u003cli\u003eEasily change chainrings without affecting power\u003c\/li\u003e\n\u003cli\u003eClearance with frame\u003c\/li\u003e\n\u003cli\u003eEnough clearance with our direct mount brake caliper\u003c\/li\u003e\n\u003cli\u003eAccurate data collection ±2.0% accuracy of strain gage measured power in full-range\u003c\/li\u003e\n\u003cli\u003eStable power measurement system at the various stepping positions\u003c\/li\u003e\n\u003cli\u003eActive temperature compensation\u003c\/li\u003e\n\u003cli\u003eOwn developed strain gauge\u003c\/li\u003e\n\u003cli\u003eSoftware compensate automatically\u003c\/li\u003e\n\u003cli\u003eQuick response and operation without stress\u003c\/li\u003e\n\u003cli\u003ePossible to start quickly\u003c\/li\u003e\n\u003cli\u003eSimple zero reset with switch on transmitter\u003c\/li\u003e\n\u003cli\u003eDirect response\u003c\/li\u003e\n\u003cli\u003eBoth left and right side connected with cable\u003c\/li\u003e\n\u003cli\u003eMagnet based cadence\u003c\/li\u003e\n\u003cli\u003eBluetooth®LE and ANT+\u003c\/li\u003e\n\u003cli\u003eWireless firmware update system\u003c\/li\u003e\n\u003cli\u003eHOLLOWTECH II crankset\u003c\/li\u003e\n\u003cli\u003eOptimum power transfer Best balance for lighter weight and efficiency\u003c\/li\u003e\n\u003cli\u003eNew designed crank arm\u003c\/li\u003e\n\u003cli\u003eMaintains high rigidity and reduces weight\u003c\/li\u003e\n\u003cli\u003e4-arm construction crankset\u003c\/li\u003e\n\u003cli\u003eIconic design\u003c\/li\u003e\n\u003c\/ul\u003e","published_at":"2026-10-23T11:49:58+08:00","created_at":"2025-12-04T12:37:47+08:00","vendor":"Shimano","type":"Bicycle Cranks in Bicycle Drivetrain Parts","tags":["Bicycle Parts","Crank Arms","Crankset","Drivetrain Parts","Dual Sided Power Meter","FC-R8100","FC-R8100-P","FCR8100P","Power Meter","Power Meter Crankset","R8100","R8100-P","Shimano","Shimano Power Meter","Shimano Ultegra","Ultegra","Ultegra R8100"],"price":99999,"price_min":99999,"price_max":99999,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":46143156158658,"title":"172.5mm -
