Wahoo Fitness BLUESC Speed/Cadence Sensor with Bluetooth/ANT+

The cadence sensor of the Blue SC stopped working. New battery and tested using stronger magnet. The speed sensor still works and reports to the Wahoo Bolt. At this point it looks like Wahoo is starting to look like Garmin in terms of reliability. At least Wahoo's plastic sensors don't disintegrate like Garmin.
I'm now using Chinese knock off brands because they are half the price of the American brands which are made by the Chinese companies anyway.;

I have had many magnet-based sensors and this one has lasted the longest (many years now) and been the most reliable. Batteries last forever too and I ride a lot. Yes it requires alignment. This isn't a big deal. If you're on the road and it quits just move the magnet a little or tilt the sensor as needed. It takes 2 seconds. It even has a light on it that flashes when the magnet goes by so you can spin the wheel by hand and check alignment before setting off. If you tighten things well it won't need adjustment often. Yes you can use the newer kind without magnets. They aren't as accurate. I use gps anyway so if I lose the wheel sensor it's not a big deal. The point of the wheel sensor is to improve accuracy. One reviewer blames this thing for elevation data stopping. This device has nothing to do with elevation data. That's a head-unit problem. If you don't have gps as a fallback can't tolerate loss off data ever and don't want the higher accuracy of magnets get the accelerometer type. Many people do.;

I have 2 of these units one on my training bike and one on my race bike. Works seamlessly with my Wahoo app and the battery only needs to be changed 2X per year.
Connects every time and set up took around 20 minutes.;

Funciona perfectamente. llevo tres meses utilizándolo y la batería sigue funcionando bien con una hora diara de uso en promedio.

El complemento ideal es un monitor de ritmo cardiaco para poder medir con mayor precisión el entrenamiento.
Es perfectamente compatible con Zwift.

Lo único que diría que me parece un punto débil es que se amarra con una liga de goma a la bicicleta y no queda perfectamente ajustado por ello se mueve cuando estás pedaleando afuera en MTB o con baches y a veces deja de medir la vvelocidad o la cadencia si se aleja del sensor del pedal o de la rueda. OPAra arreglar eso conviene amarrarlo con cinchos sin embargo eso impide que lo puedas estar cambiando de bicicleta (mi caso);

The good is that is very easy to install and sync with your bike computer without any doing of your part. Now the readings & sensors are not very accurate specially the speed sensor. The C2032 battery doesn't last long & needs to be replaced every couple of months or sooner in my case. Honestly Wahoo needs to update or replace this sensor soon or they will fall behind compare to other offerings if they want to compete. Probably they are already left behind !!!!!!;
