Great alternative to a full crank power meter. Easy to calibrated before your ride. No issues paring to my Garmin 530. Keep in mind that the single pairing transmits both power and cadence. Just remember to remove your old cadence sensor from you computer. Fit my 2021 Trek Emonda with plenty of room between the chain stay. Nice product and nice to have a standard type of battery that is easy to replace whenever that is needed.
