Have SRM powermeter crank. This is an amateur unit but is extremely accurate. Cranks have been used for the last season on a time trial bike. Overall, they are in good condition and work great, just do not need them as I sold my time trial bike. The crank length is 172.5mm and the chain rings are 53/39 standard. This is compatible with a Shimano octalink bottom bracket, but the cranks can be used with any component group. Wired crankset only. Please let me know if you have further questions and thanks for looking. I can email you pics if you want. Asking 600.00
