No more guesswork.
It’s well known that better data leads to more effective training. That’s why the Garmin Bike Speed Sensor gives you valuable data to help tailor your training plan. This low-profile sensor attaches to the hub of either wheel, and self-calibrates with your Edge-series computer to provide accurate speed readings.
The Speed Sensor attaches to your hub, which minimizes its impact on rotational weight. It’s self-calibrating, which takes the headache out of setup, especially if you regularly swap it between wheelsets. And it’s built to sync up easily with your Garmin Edge-series computer, to help you pinpoint your speed with greater accuracy than GPS alone.
The Garmin Bike Speed Sensor is available in one size, and in the color Black.
- Syncs with Garmin Edge series computers

Matthew BoweEmployeeAwesome for indoor training!
- Familiarity: I've put it through the wringer
The Garmin Speed and Cadence sensors along with a Garmin device are a great way to track indoor rides. I use it to track speed, cadence, and distance on my rollers. It makes riding indoors so much more enjoyable, and costs less than alternative options.
Joel Hauschildso far so good
- Familiarity: I've used it several times
I have been primarily using it with my trainer with the weather changing. It seems to work well and is accurate. Synced easily to my watch and I can compare the data from Trainer Road to what Garmin says that I am doing.
Steven SheffieldGearheadHard to stretch over some hubs.

- Fit: Runs small
Love that I don't need a sensor mounted to my chainstay and a magnet on my spokes any more, but wish it came with multiple holders for different sized hub barrels. I barely made it stretch around the Industry Nine Torch hubs on my Reynolds wheels. Other than that, I dig it.

Not good for MTBing
- Familiarity: I've used it several times
I bought this specifically for MTBing as loss of GPS signal throws by Garmin 500 off. So I thought this would help. I believe the problem is due to the frequent lock ups of the rear wheel is throws it off. I should try it on the front wheel but gave up.
It seems to work fine on the indoor trainer but I did loose the signal a few times there too. The GSC-10 works way better!
JenSo simple, you have to love it

I have a Fenix3 and wanted speed/distance while on my trainer, I had the speed sensor paired in a couple of minutes and the connection when I get on my bike is almost instant after I wake up the sensor with a couple spins of the wheel. It will be interesting to see if it takes the distance I ride mtn biking to a new accuracy level.

Great for trainer but sure about MTB
- Familiarity: I've used it several times
On MTB rides, I notice due to loss of satellite reception and speeds, the auto pause feature on Garmin kicking on like crazy. So thought this would be a good remedy. And so far it is!
It also works perfectly on my trainer so I can use Garmin to track it.
With it's ease to install, I can swap it from bike to bike quickly. No comparison with old magnet senor, GSC-10.
The silicone holder seems to be on the limit on some hubs but fits. Feels like I am about to rip it apart though.
Update 10/23/15, yesterday on a local MTB ride, even with the speed sensor, the auto paused kicked on constantly. I had to stop and turn the auto pause off. I suspect it maybe the distance from the speed sensor the the receiver OR the bumps. I will retest with it mounted to front wheel.
Update 10/26/15,
It appears due to rear wheel locking up during braking over various type of bumps, this pauses Garmin head unit.

Does what it's supposed to
- Familiarity: I've used it several times
Nice little speed sensor to use my Garmin Edge while indoors this winter on the rollers. It's easy enough to attach, quick to synch to my Edge 800 or Edge 500, and seems pretty accurate. Better than mounting a magnet on a spoke and a transmitter on a fork or chainstay. I don't see myself using it outdoors, but for indoor workouts, it's nice to have
I just bought one and have had reasonable success with it mounted on my front wheel. Primarily using it for XC and trail type riding. I have auto-pause set to 0.5 mph.
