Upgraded to this new Garmin Cadence sensor 2 as this new version has bluetooth which makes it compatible with Zwift. Works seamlessly with my Garmin Edge 1000 when riding outside and pairs quickly with Zwift for indoor training. I prefer this Garmin cadence sensor over the wahoo fitness as the Garmin provides a more accurate and consistent reading.
Works well when it works. This is my second one because it stopped connecting after 1 year. The battery does not seat properly over time, activates on half turn and disconnects when fully closed.
If you have a Garmin bike computer, this cadence sensor is a nice addition. The two work well together, as they should, and its nice to have a "tachometer" to go along with the speed and distance.
Using this on my bike that I use on the wind trainer, & connecting it to my Forerunner 245. It's accurate, & it's real time. Can't really ask more than that. Easy to install.
Works well with my Garmin 520 Plus. I have one on my indoor trainer bike and one on my outdoor road machine. Seeing the cadence numbers helps me get back up to speed when I get distracted or slack off. It's a great motivator for me, especially when coupled with power numbers.
