    Anyone tried the newest Garmin cadence sensor?

    I've tried to get my original cadence/speed sensor to work, without success (Edge 500 bundle-gifted).

    The head unit works fine, so I'm not sure why there even is a speed sensor, unless for a trainer. Doh.

    The sensor lit up red, then showed green when the crank arm went by, then quit.

    I saw a guy using the crank arm-mounted sensor, no magnets, no fuss, and wondered about it.

    I'd order one or two if I thought they worked, but the original one didn't, and I don't want to waste $40

    Any feedback on this type of item, or the finicky-ness of the original sensor?

    I have the new magnet'less Garmin Speed and Cadence sensors and they work great! I've had no issues whatsoever with either of them thus far.. The Edge 1000 is a different story but the new sensors ROCK!

    Wheel sensors are used to improve accuracy and precision over GPS alone. This includes the improving the auto pause function. Wheel sensors are needed for trainers as the speed and distance is always zero. What matters on a trainer is exertion level and duration, not the number of times the wheel goes around.

    The new senors work well. Check this review of the 1000 and the new sesnors, which inlcludes a table of with Garmin units the new sensors will work with:

    Questions answered. Thanks, guys.

    Now, I'll just take my original cadence/speed sensor to REI and let them re-install it. They'll do it right, I'm sure. The ANT stick works "sometimes," but I use the mini USB cable when it doesn't, so no biggie (spare laptop in the garage).

    It works well and so much easier to install and live with comparing to the old one.

    Depending on frame design the Garmin magnets aren't really strong enough. On my bike I need to angle the sensor slightly to get it close enough for the cadence sensor to consistently register. Ideally, the sensor should be within <10mm of the magnet.

    For cadence with the Garmin GSC10 I use a 3x12mm rare earth magnet self attached to the inside end of the left pedal spindle. I've also stuck one on the inside of the crank arm with permanent industrial double stick tape. They're very strong and along with the size have a longer range....at least 15mm. They should line up with the vertical line on the body of the GSc10

    I both the speed and cadence sensors and one thing I've noticed with the cadence sensor is that waking it up is something of an art. If you spin the cranks too fast, it'll not wake up no matter how many times you spin it. The trick seems to be to spin at about 50rpm for 2-3 revolutions for it to wake up proper.
