If you have a bike computer that is a Garmin or Ant+ these are must have items. I needed the speed sensor, and wasn't 100% sure about the cadence sensor but bought it anyway. Itt was a great purchase. Both devices have improved my riding by giving accurate feedback. They are very simple to connect to the bike computer, I even purchased a second set to use on my MTB so i get the same data no matter which bike i'm riding (road or MTB)
Great for tracking rides with a compatible device - I use a Garmin watch paired with these. It's good especially to get a sense for how cadence is and how it correlates with heart rate and things of that nature. Simple, reasonably-priced bit of cycling gear :)
I use this these sensors on both my full suspension mountain bike and my road bike. I also connect them to both my Garmin edge 820 and my Garmin Vivoactive Watch. Set up was really easy in both cases, and I haven't had an issue since.
i love my sensors! everything easily sync'd with my garmin 530 edge and with zwift, so now i have great data about my cycling performance. i try not to focus on my stats too hard, but it is really interesting to see your performance changes throughout a season. i set this up by myself in less than 15 minutes before an early morning group ride... so i'd say it's pretty easy.
Using the Speed and Cadence sensors with my Garmin Vivoactive 4. Works as intended and gives accurate numbers compared to my previous Cat-eye sensors. One of my straps for the cadence sensor tore after a few rides, may be due to my shoes rubbing against it.
I transitioned to an indoor trainer this January for Zwift. I have an old Garmin Edge 800 that is stuck in the dark ages with only ANT.
This sensor has both ANT and Bluetooth and makes connecting to Zwift a snap.
I moved the old ANT sensors to my commuting bike and just move the computer depending upon if I am indoors or outdoors.
I've still yet to buy a cycling computer, and use my Garmin FR 235 for both cycling and running. I got these to better measure my speed and cadence and have been super happy with the metrics it provides.
