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.
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
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'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.
This unit works satisfactorily with my Garmin Edge 820. Although I sometimes see very brief fluctuations in my speed readings, the unit delivers an accurate total mileage at the end of a ride. I do not see errant maximum cadence readings like I have with another brand ANT cadence sensor. These are quick and easy to install. I would buy again.
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.
Works as advertised. Still feel like they are the best speed and cadence sensors around. ANT is definitely still the most reliable connectivity around for both indoor and outdoor training. Pairs easily with Garmin computers, watches, and anything else that supports ANT
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 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.
When I first became aware of this sensor kit I immediately bought several for my bikes. The opportunity to remove the clutter of wires and extra sensor mounts was a big attraction.
The sensor kits have met all of my expectations. They are quickly recognized by my Edge 800. And the clutter is gone.
Prior pair needed replacing at just under 20,000 miles of all weather use.
1. More reliable than prior magnet versions (sensor adjustments often needed on magnetic sensors due to my chainstay shape.
2. Easy to change batteries
3. Batteries last over 3,000 miles
4. Less wet weather concerns
A. Cadence sensor has delayed response to bike computer and power meter
B. It would be great if replacement speed sensor covers were available. Cover gets loose over time.
