As a new Garmin 830 user I was disappointed at how slow it was at updating speed in GPS only mode. I could see from my old bike computer that the Garmin display was often way off. The speed sensor fixed it right up. I bought the speed-cadence bundle because it was on sale and they’ve both worked great: easy install and pairing, head unit detects them and any other sensors with no effort.
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.
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.
The Garmin speed and cadence sensor were easy to install and Pair with the monitor. The monitor that I have is made by Bryton And easily connected to the sensors via ant and Bluetooth technology. Bicycle tires direct offered the most competitive price for these monitors and the shipping was timely and seamless.
Both my wife and I have these to connect to our Garmin 520+ computers. They are easy to mount on a wheel and the cranks, and it is easy to adjust the location if you find yourself hitting the cadence sensor with your stroke.
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 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.
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
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!
