LEZYNEPro Bicycle Cadence Sensor Bluetooth Dual Pair Wireless, Road, Mountain, Gravel Bike, Indoor/Outdoor Training

The idea to get these sensors so I can put my old sensors (speed+cadance combine) to my gravel bike and put these to my road bike so I can use my GPS more often. I have Lezyne Micro C GPS and I got issues with them. First issue was connecting to my GPS; it says connected but not sending the signal to my GPS for speed and cadance sensors. I need to disconnect them and reconnect them until the 3rd time and it sent the signals to my GPS. Second issue was the day I bike; when start my journey, these sensors didn't keep the connection so I need to re-sync/reconnect to my GPS. This process was not as long as initial connecting. The third issue was the sensors disconnected their own while I was biking. Honestly, I like the build of these sensors and not bulky like my old one but no bueno AKA not good. I will give another try before return it.

Had trouble mounting with large hands on the hub. Instructions could be more robust. I recommend syncing each sensor after installing the batteries to avoid confusion. The speed sensor was the first selection and cadence was the second sensor on the list. When attempting to sync to my lezyne. Not a problem for the speed sensor but was a problem when syncing cadence. Once that was sorted it was great.Big bonus no need for an extra magnet also it seems like the speed sensor adds just a small amount of weight which gives a bit more spin on the wheel.

I purchased this sensor kit to replace my Wahoo Blue SC sensor. They installed easily and synced very quickly to my Lezyne Mega Color SC computer. I do wish that the cadence sensor was a little narrower. It fits on my crank but only a couple of millimeters between the sensor and the frame. I’d like a little more room so I could have options of moving it around in the crank. Seems great so far and the data updates to the computer in real time, very quickly.

I've used Lezyne products for the last 6 years. Had some connection issues with the older generation Speed/Cadence Sensor (the one with the magnet) but would take that one over the newer ones. Sure this generation looks better, but, in my experience, the connection is incredibly unreliable. Hopefully I have a *lemon*. I am going to keep trying it out, but need a much different experience to call it a good purchse.

Once I figured out how to pair these (which required a support email, because the user guide and UI are not intuitive) they work great.

Update: Several months, and a couple hundred miles of riding, these seem to be going strong. I haven't ridden in any rain or puddles, but they work great.Very easy to install. Paired to a Lezyne Macro GPS with no effort on the first try. The rubber backing seems very high quality. Haven't ridden with them yet, it's too hot, but I was impressed and wanted to write the review. I will try to update after some use.The hub of my rear wheel is tapered, so the rubber insert doesn't quite fit. It's not really their fault. I may 3d print a replacement.

Fantastic product, works just as good as Garmin, but for 1/2 the price. Very easy to install, clearly marked, so awesome.

Update: Recently got a new bike. The cadence sensor does not clear the space between the crank arm and chainstay. The unit is unbelievably tall (taller than competitors). Since it doesn't clear, the unit is pretty much useless now. Your mileage may vary.Not sure if I have gotten a bad unit, but while these newer style sensors are sleeker and rid the need of a magnet (that may interfere with spokes), they drain batteries like there is no tomorrow. The older style (with magnet) sensors did not have such problem. Until the issue is figured out by the manufacturer, I can't recommend them at all. Contacted Lezyne about the issue twice, but no response.
