“So far the speed sensor has been great, connects without any issues. The cadence sensor on the other hand does not connect to the Garmin connect mobile app at all, but will connect with a bike computer or Zwift or MyWhoosh etc… (I personally do not have a bike computer so it can’t be used on my rides) other than that well worth it.”
“I have two bikes and didn’t want the extra costs of having to buy another headset for my Garmin 840 which is an awesome bit of kit so I purchased speed and cadence bundle and an out front support for the headset. My equipment arrived from 99 bikes within 48hrs and the fitting was easy, calibration simple and saved me a fortune.”
