Digital Cameras Photo Reviews of Garmin GSC 10 Speed/Cadence Bike Sensor
Customer Review: Faulty Unit, Be Aware for Bad Manufacturing
Summary: 2 Stars
Unfortunately, as Garmin has expanded their quality control has been poor. While I believe this has the potential to be a good product, I purchased two of these units for my bike and my wife's. One of them came with an almost dead battery and a dead speed sensor (although the cadence works well). I am not the only person with this issue as the garmin support forums have had several people complain of this issue. Replacing the unit through G has been difficult as well. Their call center is slow and overwhelmed.
The second unit works perfectly as expected, and provides what is advertised. The unit seamlessly pairs with both my forerunner 310xt and my wife's forerunner 405.
So, while the product itself, if it worked w/o problem I would rate as a 4, the QC issues and issues with Garmin Customer Support make the GSC (which I am otherwise a fan of) a 2 star rating.
Customer Review: I would purchase again!

This is the 2nd Garmin GSC 10 we've purchased. I originally bought one for my bike and eventually bought a 2nd one for my wife. Compared to other speed/cadence devices that require a direct wire, this one is great. It's completely wireless and attaches very quickly to your bike with minimal set-up. All you need to do is attach the speed and cadence sensors to your bike, align the GSC 10, and press the calibration button. If it picks up your speed sensor a little light turns green, if it picks up your cadence sensor, it turns red. From there you simply tighten and pair with your Garmin device. I have a 405CX and my wife has the 310XT. Both devices paired very quickly and work great. The only thing you need to remember is to turn off the GPS feature when cycling indoors on a trainer. Unfortunately, I cannot comment on how waterproof the device is since I've never used it in the rain.Customer Review: Attaches easily to any bicycle; NOT EVERY BIKE!!!
Summary: 3 Stars
The Tech Details for the GSC-10 states "Attaches easily to any bicycle; 1-year warranty" Many retro or comfort cycle owners should verify there frame will allow alignment of the three parts to attach properly. The spoke magnet has to align with the GSC-10 sensor, not a problem.
On my Electra Townie, a comfort class bike, the pedal crank arm is located too far forward to allow alignment of the third sensor. The pedal crank arm magnet is required to align with the GSC-10 and the spoke magnet in order to measure your pedaling strokes per minute.
It is not critical for operation, but you will be unable to measure your pedaling strokes per minute. Although a general road touring cyclist, I did purchase the unit and the Edge 705 in order to measure everything I could. It was disappointing to learn AFTER the fact that I will miss a key measure.
Customer Review: Works well
Summary: 4 Stars
I use the Garmin Forerunner 305 with my road bike. I recently purchased an indoor fluid trainer, and without GPS signal the 305 is only good for heart rate monitoring. I got the GSC 10 to solve this problem, allowing two other reference points (rear wheel speed and cadence) for feedback while cycling indoors.
The GSC 10 has performed exactly as I had hoped. Integration with the 305 unit was simple. Installation time was around 15 minutes, mostly for positioning as I experimented with tolerances - because I wanted to know what the limits were for picking up a signal before tightening the zip ties firmly in place.
The unit has done the job well. I can not comment on how well it holds up to weather, as I live in a place that rarely sees any rain. It is definitely great for trainer cycling, and for cadence monitoring indoor or outdoor.
Customer Review: Not Waterproof
Summary: 2 Stars
I'm a big fan of Garmin computers, and especially the mapping features of the 705. If there were any other computer that did what theirs does, the GSC-10's sensitivity to water would be an unacceptable design flaw. It's supplied with zip-ties (requiring a cutting tool to remove it), yet it won't tolerate even a small amount of water such as from washing one's bicycle or riding in light rain for over an hour. Garmin is honorable and will replace drowned GSC-10's under warranty. (I'm on my third one.) But it's really unacceptable to have to remove the sensor any time I wash my bike and any time rain is anticipated, and to have to do without it for a couple of weeks, or longer, any time I get rained on unexpectedly. They're replacing so many of these that, after a wet spring in the eastern USA, my last warranty replacement was backordered for five weeks.
