This kit is designed to replace the speedcadence sensor on your rear stay. It also eliminates the need for magnets all over your bike. The one with four ears, is the cadence sensor and it attaches to your crankarm. I keep thinking that one of these would be great to take to a spin class, tape on the crank arm and with my Garmin, know my cadence. The other fits around the front or rear hub and is the speed sensor. In my mind, unless you ride the rollers, or in places where there is no GPS coverage, this device is not necessary, The computer unit will calculate your speed using GPS. If you need both, they work great, and they eliminate that ugly old speedcadence sensor on your stays and eliminates magnets.
I track my road rides on a Garmin watch, and wanted an easy way to quantify my workouts when I rode my track bike on rollersmag trainer. The speed and cadence sensors attached in a minute and paired with my watch just as quickly. Finally, something that works as advertised.
Only used it for a couple months so don't know about battery life, but so far I like the ease of use.
Cadence and speed sensors work as advertised. Simple add ons, but worth the modest price to get accurate read outs of cadence and speed. Highly recommended.
Plug and play, could not be easier and more effective.
I've tried other brands ANT and Bluetooth speed and cadence sensors. I don't expect much from them. They should be durable, be easy to fit and remove, allow one to change the battery, and just work most of the time. The Garmin sensors deliver on all counts when others don't. I've still not changed the batteries in the first set I purchased more than a year ago. It's easy to move them between bikes but they are inexpensive enough not to have to do so. Multiple sensors may be connected to a single head-unit, and I've yet to suffer any data dropouts or failures. Solid.
I have this on my road bike and decided to replace the speedcadence sensor that comes with the Garmin 510 that I had on my TT Bike. It is easy to install and worked without a hitch. Is much more aero and clean looking than the sensor sitting on the chainstay. The only disadvantage to this is that if you use a trainer that doesn't have cadence speed built into the trainer but you have to remove your rear wheel, you are out of luck.
New bike, needed new cadence and speed sensors. These are the latest iterationreplacement for the previous model, GSC-10
I think the price is higher for the two modules, and that's really the only negative that I see.
Mounting was super easy - no magnets to align, no sensor arm to set, just use the included o-rings (several sizes included) for the cadence sensor. The speed sensor sort of wraps around the hub (can use either front or rear).
I had zero issues pairing with an Edge520, I set the wheel diameter to the right value, the speed sensor's just as accurate as the GSC-10 on another bike, or the Bontrager module on a third bike.
No issues at all in the several months this has been in use.
Lets me switch bikes without having to move the sensors.
Very easy to install and flawless link with a Garmin Edge 1000. This set was installed on a second bike. The firdt bike got over a year out of the battery.
I bought these to replace the older cadencespeed sensor paired to my Garmin Edge 500. I had initial setup problems with the Edge not detecting the cadence sensor despite following instructions. Almost gave up but switched the Edge onoff a few times and suddenly it started working and has been trouble free in 2 months of operation. As with most Garmin electronics, price is too high for what it is IMO but I like not having the bulky chain stay sensor anymore. Took off one star for initial setup problems and being overpriced.
I bought these to replace a GSC-10 on which the speed sensor stopped working. It went on easily and paired with my Edge 810 without any problems. It works, for how long I don't know.
I bought this to use on a fat bike where a normal speed-cadence combo sensor won't work. So far it's performed flawlessly. Connects quickly to my non-Garmin computer (Bontrager Node 2.1). About the only flaw is it's expensive for ANT only.
After purchasing this set up I have had zero issues with my sensors. No more shifting parts or sliding magnets. I can get on and go. I had no problems getting these to communicate with the head unit and they are recognized immediately upon power up. At first I was swapping one set between two bikes and it was easy enough. After buying a second set it's just a matter of selecting the bike on my GPS and it ready. Great product and a side note, my batteries seem to last longer. Worth the money and much cleaner look.
These new sensors from Garmin are great. There is no fiddling with alignment trying to get the sensors and magnets aligned. Easy to switch between bicycles so only one set is needed. To get the Garmin to recognized the speed and cadence sensor you may need to spin the pedal and wheel. Just make sure that your Garmin Edge can recognize these units before purchase. It works with my Garmin 810.
My initial impression was to rate this product five stars in both categories. I really like these units. They clean up the bike. Eliminate the clunky cadencespeed pickup from the chain stay and the magnet from the spokes.
My issue is with the mounting system for the cadence unit. When I first mounted it I was sloppy and my shoe rubbed against the mounting rubber bands. Wore through them on the first ride. I took great care when remounting to be sure the shoe would not rub. Worked fine for about two months and now I see one of the three bands in the mounting strap has broken. I'm in jeopardy of loosing the unit.
I do not know of a source for spare mounting straps. I'm using a double sided sticky strip and very narrow zip ties. I wish the unit were designed with zip ties in mind. They would be as thin as the current mounting strap, more durable and replaceable.
i hated the magnet on my back wheel, and i thought the cadence sensor was hideous... anyway, when i saw my buddy riding he had this sensor on his back wheel, and he told me Garmin has a new speedcadence sensor. I had to have it.
I had problems hooking it up...but come to find the battery was dead. Nice... Anyway, i replaced the battery and it's worked solid ever since. I've NEVER had a problem with it.
And, it looks a whole lot better than your ugly sensor dangling off your bike!
Both the cadence and speed sensor are easy to install, and easy to switch bikes. Stay connected to head unit. Very pleased with this new version as the older cadence unit broke easily and lost connectivity frequently. I hope the battery life is long and easy to change.
I had the older cadence/speed sensor which used a magnet on the crank arm and one on a spoke but when I got the new Edge 1000 decided to upgrade. I question the silicone bands ability to withstand breaking down in the elements but like the way they connect. Sometimes while riding the cadence numbers will jump around a little, maybe - 10 rooms and the stabilize for awhile but it averages out at end of ride. Looks nice not having the big sensor mounted to the chain stay.
Have had no problems since my original purchase on previous units over a year ago, so I don't expect any from this unit. It has worked perfectly with my wahoo element.
Road cyclist, all gadgetry is cool & helpful,a breeze to apply to bike,wireless,no setup I have Garmin 820 it finds the sensor.After they're picked up, the sensor icons appear on the top of 820 screen so you can see which ones are active,good for troubleshooting faulty sensor. Good stuff
