I'd bought these as requiring a service on the LHS pedal as it was not rotating smoothly. I have since taken apart the pedal, cleaned and regreased the pedal body and it now runs as smoothly as the other one. I used these during Tour de Manc and the numbers were comparable to my power meter crank. ANT+ and Bluetooth both work fine. Selling as I prefer SPD pedals to SPD-SL and I don't need dual sided. Ensure that when putting in AAA batteries, the bolt holding them in place is fully tightened as I initially thought the pedals were broken due to this being slightly loose. I will only sell within the UK and will not ship to new accounts.
