COOSPO Cadence & Speed Sensor for Cycling, Wireless Bluetooth & ANT+ Bike RPM Sensor for Cycling Computers, Compatible with IP67 / Rouvy / Zwift / Peloton / Wahoo / CooSporide

I've been using this cadence sensor for over a year now and feel driven to review it at this point. This is due to the low drama experience I have had with this product.I've been running this for road cycling with about 2,863 cumalative miles logged. I have experienced several rainstorms also during my this time while riding. No issues.Pros-Battery life- original battery lasted over a yearDependable-always works and always connects (I use ant+)Accurate- I have a cadence range I prefer and this sensor has always lined up with my expectations and experience.Reacts quick enough to changes. No complaints when going from 0 to 100 to 0 cadence. This mostly happens in pace group.Neutral thoughts on the rubber rings. They are a wear item that I've had to be creative to replace. They will not last long. Understandably.Cons-none.

Followup to followup review----I reached out to the mfg about the broken ear causing the sensor to fall off, and preventing it from being mounted. After verifying that I mounted it correctly, they quickly send me a replacement. I wrapped the sensor with electrical tape just to be safe. Looking at the sensor after roughly one week, I can see the silicone band snapped under the tape. So there is definitely some weakness with the band, as this is the second one that broke.Followup review----On one of my ride, I glanced down and saw my cadence being blank and noticed the sensor not there anymore. I saved and replayed my ride to see where the cadence stopped, rode back 3 miles and found the sensor Turns out the one of the ears where the silicone band hooks onto broke off, just as I had concern about.I went back a couple of days later and found the rubber backing along with a fragment of the silicone bend. So now I am not sure if the broken ear or band that caused the sensor to fall off. Now I have to wrap it with tape after mounting so it doesn't come off.After less than 500 miles, that's pretty fragile. It might be the reason I lost the original one. Dropping from 5 stars to 3.One thing I also noticed is the cadence update is a few seconds behind, so if you mount this on your stationary bike and want to see your peak cadence, you are not going to get that.Original review----This is a replacement for my last Coospo sensor that fell off my crank. The replacment works fine as expected. I do like the fact it has ANT+ and BLE, so it could send data to my bike computer and phone at the same time. Weird that a 2 pack cost more than 2 single pack, which is what I purchased. I read you can't pair both at the same time via BLE, but I using another brand's speed sensor, which is no problem.A couple of minor issues. The form factor is squarish, which makes it stick out when attached to a hub or to my old school crank. This time, I mounted in between the spider on the chainring side so nothing would bump into it (unless a dropped chain does). The other thing is removing the battery to change between cadence and speed sensor mode. I've had others where there is a tiny switch internally. By the time the battery needs to be changed, I would have forgotten if the blue or red light indicates it being in cadence mode. I would find out there is no cadence reading, then have to go into the app or bike computer to see what type of device is discovered. Probably have to stuff the instruction into somewhere obvious, which I would not remember 8 months down the line.

These work great.

I have had the CooSpo heart rate monitor with great success and usability. So I ordered the speed and candence sensors. They arrived quickly. The picture directions are clear about the install. Setting the modes between speed and candence is as simple as removing and replacing the battery.The connection to the Wahoo Bolt was quick. I connected using ANT+ since it had the strongest signal at a distance. The Bluetooth connection did show a weaker signal. Also Bluetooth in general uses a crowded spectrum so living in a urban population, the use of ANT+ is better.During my first rides they work great! The speed sensor wakes up at about 4-5mph after that it's accurate from 0 on your ride. There is a latency I noticed of 1-3 seconds in the data to the head unit.These sensors replace the Wahoo BlueSC and are far better than the magnet sensors.For durability, I am not sure how long the rubber neoprene bands will last. They give you many extra bands. I'll update my review if I have an issue.Great buy, easy to use, excellent value! I would recommend them.
