    Great Upgrade

    • Familiarity: I've put it through the wringer

    The new speed and cadence sensors are a major upgrade from the old sensors. No more having to mess around with lining up magnets and sensors. These are pretty much set it and forget it. Haven't had any issues with them.

    Pretty Cool

    • Familiarity: I've put it through the wringer

    Bought this for riding my bike on my trainer. It's super easy to attach to the bike and connect to my Garmin Forerunner 235. Connects automatically after initial set up. Only problem is that the construction feels a bit cheap and has the potential to fall apart. However, so far so good.

    Indoor Training

    • Familiarity: I've put it through the wringer

    I picked this set up for my sons road bike, so he can train indoors with his Garmin and also learn to spin at different cadences. Easily paired up with the Garmin 520 head unit and has worked great with no issues. If you have any questions about Garmin product or other gear, feel free to reach out to me.

    So easy to swap bikes

    • Familiarity: I've put it through the wringer

    I purchased these because my old sensor was not ant+. I have been very satisfied; particularly with how easy it is to move them from one bike to another. With no outside magnets to line up, you just loop the rubber band and go! With automatic calibration this means the speed sensor works with any wheel size and mount on front or rear. I say this because one wheel hub was so thick I was afraid of breaking the rubber fastener; no problem, put it on the other (thinner) wheel hub. Have put these through lots of rain and dirt, left them on my bike while washing, and shaken them up gravel riding and mountain biking - still working great.

    Nice upgrade

    • Familiarity: I've used it several times

    I just put this speed and cadence sensor on my bike. They are super easy to install. The speed sensor just goes around your front or rear hub, and the cadence sensor installs on your crank with a rubber band (included). The setup is super easy. I had the previous generation cadence sensor, and while it did work just fine, the new version is easier to install and makes it easier if you want transfer it to other bikes.

    Easy On Easy Off

      I tend to switch out my wheels quite a bit and this sensor is very easy to move over to my other wheel sets. In the past I've had to deal with lining up magnets which was a real pain. I have had some issues with it taking a long time to "wake up" and had to go buy a new battery which apparently wasn't the cause.

      Easy On Easy Off


      • Familiarity: I've put it through the wringer

      After 6 years my GSC-10 started to give me problems and it needed to be replaced. I find that this two piece unit needs time to wake up and will on occasion drop during a ride (speed or cadence). Accurate, yes, but I just don't feel it's as reliable as the GSC-10.

      Love it

      • Familiarity: I've put it through the wringer

      Used to have the old one where you have to use zip ties to hold the cadence sensor and mount the magnet. Pretty lame and not very portable. This one is way easier. Cadence sensor was easy to mount and sync. The only problem I had was that the speed sensor had some issues getting detected. Some advice: if the speed sensor doesn't sync, take out the battery and wipe the little oil off. Mount battery cage back on and smack it against the back of the pawn until you see the light on top blink. I bought another pair for my other bike due to me being lazy.

      Awesome! No magnets!

      • Familiarity: I've put it through the wringer

      Attaches simply and quickly. No magnets, pair automatically with my Garmin 510. Great sensors. 2000 miles so far.

      Worked first time. Zero issues with 510

      • Familiarity: I've put it through the wringer

      I got the new magnet free speed / cadence sensors to go on the second bike. Connected without an issue. No spikes no delays. Easy to attach and no chunky sensor unit attached to the frame

      Unanswered Question

      I have Garmin GPSMAP® 62s. Does sensor really work with my device? I can not find information about it in the Internet.
