These are great for trainer use, giving you interesting data when you have to ride in place. Meanwhile, if you have to load your bike for a drive for a ride, the speed sensor is a bother. It will register each walk from house to car as a ride, and post that amazing data to strava. Took it off after getting kudos on one too many .39 mile rides.
These work well, but I didn't ask for clunky-looking items to mount on my crank arms and hubs. Why did Garmin discontinue the dual sensor that mounted neatly on the chain stay. Probably because all of those that I owned eventually failed. All they needed to do was update the housing and seal it better.
The old cadence sensor required a magnet affixed to the crank and a transmitting unit located on the lower frame arm. Both required tight tolerances and easily could get out of alignment due to bumps or whatever. The new unit attaches to the left crank arm and can't get out of alignment. The speed sensor worked off the real wheel magnet and cadence/speed sensor. Again, the unit required tight tolerances and easily could be dislodged and require adjustment. The new speed sensor is great as it attaches to either hub and requires no further adjustment. Both units pair well with my Garmin Edge 500.
This combo was really easy to set up and use. The only issue was the mounting system for the speed sensor. The bands aren't long enough to accommodate an internally geared hub but I was able to add an additional band I had. Using it on my recumbent on an older trainer to add some stats for motivation. Easy to pair with my phone and Garmin vivoactive 3 watch once you get the hang of it.
I never used cadence before, that was really good know. The speed sensor is not necessary if GPS working well but it can help when things are fuzzy on GPS. It really is nice for use on the trainer and that is probably the best thing for me about the Garmin
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.
Just ordered my second set of Garmin Bike Speed Sensor and Cadence Sensor Bundle for another bike. While these sensors are fairly easy to transfer among bikes, Their price is right for me to have simply purchased a second set. These new sensors work like a champ and have a much lower profile than the original Garmin Speed/Cadence sensors. Highly-recommend!
Instructions to install and set up the sensors were easy to understand. Paired sensor to my Garmin 235 watch. Speed and cadence sensors calibrated automatically while riding. Sensors allow for additional statistics to be added to your Garmin connect. Works very well. I recommend adding these sensors to your bike.
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 :)
These sensors are better than the first models. Easy set up and pairing. So far the battery had lasted a cycling year (winter excluded). Installing the battery takes time like everything else. Both a second pair.
These sensors are on all of my bikes now replacing the old type which had magnets on spokes and crankarm. They work great right out of the box.
When you need to change the battery in the speed sensor, be careful to not bend any contacts or remove ANYTHING other than the actual battery.
This is the second set I've bought. I have them on both road bikes and have given them names to help identify the bike I was riding later. Pretty easy to pair, it took a few minutes to figure out how to set a custom wheel diameter. Works great and helps keep the GPS honest.
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)
