    This is my third power meter from PMC and as usual great customer service and lovely communications. In regards to the stages PM, this is my second 3rd Gen and so far no issues with both and they work as expected with logical and comparable power readings. I strongly recommend PMC and stages PM for every one interested in keeping track of their training objectives.

    This is actually my first power meter. It is very user friendly, easily compatible to my devices and so far have had zero issues and not expecting to. Josh was super helpful with questions I had and helped me narrow down my choice. Would totally buy again from PMC.

    I’ve been using a Stages Gen 3 power meter on a Shimano R8000 left-side crank arm for about a year. So far it’s been almost flawless. I’ve used the power meter extensively both indoors on Zwift and outside. Initial battery lasted more than 2,000 miles. During that time, the meter had a few brief power drops to zero outside or when connected to Zwift. That was annoying but it rarely happens. I’ve ridden in the rain and washed the bike several times with no problems. As for accuracy, it’s within 5-8 watts of my Favero Assioma power meter pedals I used to have. Those Assiomas worked well too but the release tension was so high I injured my knees. So the Stages works better for me because I can use any pedal system I want. Be careful when replacing the battery to ensure the rubber o-ring seal is installed correctly and no contaminants gets inside. And don’t install the battery backwards like I did, it’s a pain to get back out. It’s a solid and reliable power meter.

    I’ve only been using my power meter for a few weeks but so far it’s been great. Having the watts display on my Garmin 520 has really been motivating, seeing where I’m spinning too fast or grinding too hard and wasting effort has already resulted in better average speeds (wind permitting). Having a more accurate estimate of calories burned is also quite motivating, without the power reading the Garmin unit apparently uses heart rate to calculate calories burned. I’m heavy for my size so my heart beats faster than it should making it seem as if I’m burning more than I actually am. I went from having it show around 800 calories an hour to about 600, I’m sure it’s not completely accurate but certainly better than before.

    My first power meter was installed at the end of last March. So far it has been providing valuable information for my motivation and management for my performance. I had been worried to buy whether it could be installed or not, because my Treck Emonda SL5 of 2018’s had very small clearance between the crank and chain stay of size 50. I would like to inform my data for prospective users as follows:
    Crank + sensor : about 22.8mm
    Min. remained clearance between sensor and stay: about 3.1mm
    I hope this information help them!

    Next to my helmet, the best riding addition I have made to date.
    Easily justifies the price. Paired with my Yahoo Bolt well.
    Amazing amount of data for each ride.
    The information provided is useful and makes riding so much more fun and helpful to training.
