PioneerSGY Shimano Dura Ace R9100 Power Meter Crankset (Return to Product Page)

I haven't had the meter for very long. However, I've been using power meters for training and racing for 17 years. I needed a power meter for my new Trek Emonda with a BB90 - choices were limited so decided on the pioneer. Set up was easy - best advice is to watch the Pioneer YouTube video on how to set up a ANT meter with the Pioneer dual leg power meter. Pairing and calibration to my Garmin 520 was very easy following the instructions in the YouTube video. The down side (why I give it four stars) is you must use the pioneer supplied magnets for cadence and have to stick them on the frame. Most other power meters have accelerometers so there is no need for magnets - my biggest complaint. The Pioneer Power Crank (Shimano 9100 with strain gauges and pioneer electronics installed) is not much heavier than the stock 9100 crank. Pairs nicely with the Garmin 520 so no learning curve with a new head etc.. You need 2 type 2032 batteries for each side of the crank. So far the meter seems accurate and is within accuracy of my Quarq and power2max meters. I prefer Quarq but they don't have a BB90 that would fit my Emonda. The Pioneer is a good alternative.
