These sensors are much easier to set up and use than the former speed and cadence sensor that used to have to be attached to the chain stay and then adjusted so that it could read the magnets on your rear wheel and crankarm. The only difficulty with installing, if you have clumsy fingers like me, is to stretch the band around the crankarm or the wheel hub and get it into the slots on the sensor. But once it's on, it's on. Seems to be very accurate. Now use these on all three of my bikes.
These sensors have been the same for a number of years now. Adding them as I add bikes and they are easier to install than ever. One of two may had a dead battery so I changed it before attaching to the bike. Always have a couple of 2032 batteries on hand for your bike stuff.
Bound easily to a Lezyne Super Pro GPS unit. In fact it works better than the Lezyne sensor's. Except that the GPS doesn't detect the battery charge. But it was spotty with the Lezyne sensors anyway. Even when new. I've only used the Garmin sensors a couple of times. But so far I'm very satisfied that they even work with the Lezyne GPS. The Lezyne sensors are really cheaply made and suck the battery down really fast. Even when not being used. The quality of the Garmin sensors is far superior. And the price isn't much more than the Lezyne sensors. So far I'm very satisfied with the Garmin sensors. I may have to buy another set.
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.
These guys are easy to install (much better than the previous generation) and work well. Connecting to my Edge 530 was easy and I don't notice any dropouts. The rubber bands seem sturdy and battery life is extremely good. The cadence sensor is essential if you're a data nerd. The speed sensor may not be so important, because the Edge also tracks speed. However, some online reviews suggest speed is measured more accurately by the sensor. You also need a speed sensor if you use an indoor trainer, or if you ride in an area where GPS frequently drops out due to buildings, trees, etc. I have a couple of speed sensors (one for each wheelset) -- they're a pretty cheap add-on if purchased in the bundle with the cadence sensor.
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.
Ordered these to work with my new Karoo Hammerhead II and I was pleasantly surprised how easy they paired up together! They work great on my road bike, couldn't ask for anything more! Great price, super fast shipping, definitely scored! If you're in need of some sensors and are biking on a budget, these are the ones to grab!
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 :)
The moving sensor is great for if you are riding in areas where the GPS can be spotty. I enjoy being able to view my cadence and having my avg cadence at the end of a ride. Even got one for my girlfriend who now loves checking her cadence.
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 theyâ€™ve both worked great: easy install and pairing, head unit detects them and any other sensors with no effort.
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.
These are working great on my stationary bike! The Cadence showed exactly what I was getting while using the Moov cadence ankle sensor (btw- Moov is more accurate for swimming than my Garmin 935!). The speed sensor is rigged on the front freewheel and I am satisfied with the speedmile readings even though it's not on a actual 700cx23 hub like it's designed to be.
