Just installed and that wasn't easy
I just installed the GSC sensor and it wasn't easy. Still haven't seen a light on the cadence and only twice with the speed. The largest band provided barely worked on my Ultegra crank arm. I was afraid of breaking it. The instruction didn't say which wheel to installed it on so I used the rear so I could use it on the trainer. Again I was afraid of breaking the casing. The real problem was pairing. Finally I figured out on my Edge 800 to use the “speed and cadence selection” thanks to a forum. This underscores Garmin very poor instruction resources. A few simple company youtube videos would eliminate my biggest complaint about Garmin's products.
A Good Alternative to the GCS 10
I purchased this product for an older bike as I was wary of using the GCS 10 on it due to clearances being very tight to the wheel and crank arm. Using both of these sensors has resolved this issue. Like the other review, I did notice pairing was a bit difficult and once paired, the data was erratic for the speed sensor. After a quick check over everything, I replaced the battery in the unit and everything has worked superb since then. I suspect since movement wakes the sensors up, they have been on ever since they were produced since shipping and stocking them would bang them around in the box.
Avoid, ANT+ compatibility problems
I had hight hopes these new sensors replacing my old GSC 10. However I ended up disappointed. Somehow, Garmin has managed to create ANT+ product that has issues with at least some ANT+ head units. Including some Garmin itself makes. I attempted to use it with two different head units. Garmin Edge 500 and O_Synce navi2coach. Cadence sensor worked kind of OK with both of them. However it had noticeable delay of about 3+ seconds after I start pedaling and head unit starts displaying non-zero cadence. Delay with old GSC 10 combo speed/cadence sensor was not this noticeable. The speed sensor is where things more or less completely fell apart. When I attempted to use it with Edge 500, it kind of worked some of the time. Then Edge 500 would lose connectivity with it and wouldn't reconnect for a very long time. When attempting to use it with navi2coach, it would reliably connect and stay connected. However, speed readings were complete nonsense. It would show zero speed for 15-30 seconds after I started riding. Then it would show some speed reading which would update maybe every other 15-30 seconds. After coming to full stop, it would still show some speed (e.g. in 8-10 mph range) for a very long time before finally dropping to zero. Interestingly, Edge 500 would not display ANT+ ID of either sensor on the sensor info page. It would just show either dashes or zero for both sensors. Even after several pairing attempts. On the other hand, navi2coach paired with both without problems and happily displayed their ANT+ IDs. I'd stay away from these sensors. Get the "old" Garmin GSC 10. It worked flawlessly with every ANT+ head unit I had in past. Yes, it's a bit bigger, it has magnets, but at least it works reliably. I don't know what and how Garmin managed to mess up with these two new sensors, but they did manage to do it.
Works as advertised
Both sensors went on as expected, a little tight fitting my fingers between the spokes on a 32 spoke wheel. I was concerned the bands might snap as I stretched them, but they are very tough so no problems. The Ant + linking worked with no issues. I have 3 cadence, 2 speed and 1 heart sensor on my Garmin 520. Picking the correct pairing mode was a bit confusing(note the number of sensors) but the correct sensors seem to be automatically paired now that I have them programmed. No issues with info dropping out so far.
Does what it says
I ordered the combo on Tuesday; it shipped on Wednesday, and I received it in FL on Friday. On installation, nothing happened--the units would not pair. I replaced the batteries with new ones, which solved the problem. All I had to do was set the Edge 500 GPS near the sensors, and they paired immediately as soon as I started the search function on the GPS. Installation was easy with the included O ring type mounts--it took about 30 seconds each.
Better than the Last
LOVE the ease of installation and pairing with my Garmin 920xt and Garmin VivoActive! ABSOLUTELY seamless. FAR easier to take off to replace batteries. Hoping that the bands used to strap it onto the crank last (or will have replacements later)
Added Sensors Improve My Cycling Data
The speed and cadence sensor easily synced to my Garmin Tactix Bravo training watch. THE BATTERY FOR THE SPEED SENSOR WAS DEAD ON ARRIVAL. Make sure you have spare CR2032 batteries should your unit arrive to you with a dead battery.
Great for indoor training!!
Assembled both units on my indoor training bike, and it’s nice to have a computer that records both cadence as well as speed on the Garmin 520 plus.....
Works as expected
I have the 920XT and it pairs up almost instantly. I'm extremely satisfied with this product.
