I bought this Garmin sensor bundle while on sale at biketiresdirect.com. I say that they were on sale because it was the lowest price that I have found anywhere for OEM components. So far these work flawlessly for my beater bike that is primarily rode during foul/winter weather. Overall, I am very pleased with this purchase and could not be happier. By comparison I would often lose signal with cheaper aftermarket systems that would make concentrating on the ride a little more difficult. To a point you get what you pay for.
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.
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!
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.
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 :)
I recently converted to Garmin after 20 years of Polar use. I initially repurposed my bluetooth speed and cadence sensors, but when a deal came up on Bike Tires Direct for the Garmin sensors, I decided to go for it. The sensors are easy to mount and connect with a Garmin head unit. And if it's a requirement, they're much easier to move between bikes as the mounting mechanism is similar to a rubber band, and no magnets are required.
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.
This speed and cadence sensors work well, super easy to add to my KaRoo2. I have no complaints in mounting them and having it integrate with my bike head-unit (KaRoo2).
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)
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.
