Reviews
Was looking for an option to add power to the road bikes after having power measurement on the trainer all winter. Review based on six weeks of having power meter in service on 2019 Trek Domane with Ultegra groupset. PM is a good fit, no interference issue at all. Installation was quick and simple. Integration with Wahoo ELEMNT Bolt v2 has been seamless. Took a few times to figure out the process order to calibrate the PM when starting up the ELEMNT before a ride, but sorted that out and calibration is quick and easy. Definitely recommend.
