Digital Cameras Photo Reviews of Garmin GSC 10 Speed/Cadence Bike Sensor
Customer Review: Works well with my MTB
Summary: 5 Stars
The GSC 10 uses two magnets to pick-up the speed (magnet on rear-wheel spoke) and cadence (magnet on the inside of the left crank). The installation is pretty straight forward, although, the illustrations in the directions were not the most useful.
The system has worked well so far. I have not been over the worst 'bumpy' areas yet on my MTB but have been through some rough terrain and nothing came loose.
The FR-305 is supposed to use the speed from the GSC 10 when it cannot get a lock on the GPS satellites. When MTB'ing, which many times involves making many small turns, the GPS mileage reading tends to be a little short. Thus it would be ideal of Garmin could somehow combine the readings from the GPS & GSC 10 to get a more accurate reading.
Customer Review: Ant+ sensor
Summary: 5 Stars
Arrived and installed with no issues, paired up with my Bontrager Node 2 computer without a hiccup. As a note of interest, I used a magnet about the size of a dime on the end of my pedal (ferrous metal) that faces inward and aligned the sensor to that magnet. This eliminated the need for tie wrapping a magnet to the crank and it is out of sight. The magnet is strong enough to remain attached to the pedal and is recessed enough not to be knocked off. Even if it falls off it is cheap to replace. Very clean. Someone should market a magnet insert to fit the allen wrench socket, this would certainly get rid of a lot of unsightly, unnecessary tie wraps. Four stars for installation as it needs to be properly aligned and adjusted, not plug and play.Customer Review: Garmin GSC 10 Speed Cadence sensor

I am using this on my second bike - and it and the entire Garmin Edge 305 system, works very well.
The Edge 305 has multiple bike profiles, so I've tuned the second profile to this sensor.
Care needs to be taken to install the sensor correctly so it aligns properly with both speed and cadence magnets.
The only observation is that the cadence magnet, the one that sticks on the left crank, is a little tricky to space relative to the sensor. In one bike it required a home-made spacer, such that it would bring it closer (within spec) to the sensor. This will depend on your bike and as I said I only had to build this for one of my bikes. Still, it would be nice if Garmin offered such a spacer.
Customer Review: Great product. Unexpected additional functionality.
Summary: 5 Stars
I was hesitant to buy this unit since I already owned a reliable cyclometer with cadence. I own the Forerunner 305, not the Edge unit, so biking was not my main concern. However, now that I use my Forerunner for biking too, I wanted this unit so that I could download cadence data with my other measures from the Forerunner. It works great for that purpose. I was also pleasantly surprised to find that when riding indoors on my trainer with GPS turned off, the Forerunner reports SPEED and DISTANCE as well. Of course, it's not entirely accurate depending on gearing and such, but it is a nice measure to have that I didn't expect. Great unit. A little pricey at $40ish but once you have it, you forget about what you paid.Customer Review: A must have for you Edge 305
Summary: 5 Stars
I bought the Edge 305 w/o the cadence sensor thinking I don't need it but I was wrong. Once you realize what the Edge can give you for information and you start to plot everything ( I use SportTracks )you became addicted and you want cadence chart too !!!
Furthermore, the sensor allows you to get speed even when there's no GPS signal ( tunnel, cities, etc). A fact that overlooked.
Easy to install and the red/green light tells you if the unit senses the magnets which have to run pretty close to the unit. I would suggest you test the unit on your bike in a rather dark area to make it easier to look at the ligth on the unit.
