Shimano 105 R7100 175mm 12 speed crankset with INPEAK power meter This came on a new bike but I removed it as I need smaller cranks. The chainring is 52/36T and the power meter is INPEAK Powercrank E (single sided left arm). It’s been on 1 ride so everything is basically as new. The power meter pairs via Bluetooth and works really well. It just wakes up when you start cycling. Includes power cable for charging. Normally a £250 add on!
