The Garmin 010-10644-00 Speed/Cadence sensor (GSC 10) can monitor your pedaling cadence as you ride with this self-calibrating, wireless speed/cadence sensor. It measures and reports your pedaling strokes per minute, providing feedback for optimal performance. Use with the Edge 305 or Edge 305CAD, Included With The Edge 305CAD GPS Plus
A good companion for Garmin's Edge 305 and 305CAD cycle computers and the Garmin Forerunner 305 personal trainer, the GSC 10 monitors your cycling rhythm for up-to-the-minute results and later analysis. The self-calibrating, wireless unit measures both speed (in pedaling strokes per minute) and cadence , then provides feedback to the user for optimal performance. You can later feed the results to Garmin's Training Center software, which helps you tailor your workouts to meet specific goals and objectives.
Like the Garmin heart rate monitor, the GSC 10 attaches easily to your bike, where its sensors detect signals from your wheels and send the information wirelessly to your personal trainer/cycle computer. It's also backed by a one-year warranty.
This was installed in under 10 minutes and it was my first time installing such a device. Instructions were easy to use and no steps had to be repeated in order to complete the install. I paired it with my Forerunner 305 in a matter of a few button pushes I was in business on my stationary bike. The data from Garmin Connect was cool to have and I should gain insight into my cycling. When I bought the Garmin Forerunner 305 I anticipated this purchase as a potential add on. This combination was still a price leader but with great results and no compromises.
I really like this product. I like not having wires drapped around the bike. The tradeoff is that it requires a battery.
I am using it with the Edge 705. I really like the data that is provided by the device. The speed / Cadence sensor is great when the bike is on the trainer as it is located on the back wheel.
I am totally satisified with the device. I purchased it on Amazon. I am happy with the price that I paid compared to other sites. It showed up when promised. And worked as advertised right out of the box.
Purchased this device to synch with my new Garmin 310XT. Turns out the ANT communications simultaneously works with my Trek bike computer - which is sweet! So, I could use my Trek HR monitor strap and get rid of the temperamental Trek sensors (that wouldn't talk to my Garmin). The beauty is that I can monitor cadence, speed and HR on the Garmin and the Trek simultaneously. That means faster transitions from swim to bike to run since I can just keep the Garmin on my wrist.
Nice to get unexpected "features" when buying a product.
I got one of these with my Garmin Edge 305 Cycling GPS system and mounted it on my road bike. It works very well and seems quite accurate. This second one is for a stationary bike I have.
My only problem is that the first one I got has cracked on the speed sensor arm where the screw is that holds it to the main unit. So far it is holding in place, but it won't take much to break it loose. No speed sensor would only be a problem on a stationary bike since the GPS can calculate speed on a moving bike. Cadence is what I really wanted this for to begin with.
Since the speed arm seems fragile, I don't think I would recommend using this on serious mountain bike rides.
Relatively easy to install. Make sure to force the head unit to scan for the cadence unit after installation.
