I have a Wahoo Fitness KICKR trainer and a Stages Power Meter as crank arm. Since my Garmin Forerunner 920xt can only connect to one ANT+ power meter at a time, I must choose between getting power+speed data from KICKR or power+cadence data from Stages, i.e. speed or cadence but not both.
Would it be possible to attach a Garmin Speed Sensor to the side of the KICKR's flywheel and get accurate ANT+ speed? Don't know if the speed sensor will work in this "flipped" orientation. See the purple sticker in photo below.
