Has anyone used the hub based speed and cadence sensors for garmin bike computers. I want to switch from the gsc10 because the way I have to positioned to pick up cadence/speed it sticks out from the chainstay and hits the wind. Wondering if switching to this will be as
Accurate and would move it out of the wind.

I made the switch when I got my edge 520. I like them and they feel every bit as accurate as the GSC-10. Though if your GSC-10 is working fine then I probably wouldn’t worry about it too much. I only made the switch since I got a very good deal on the edge 520. Can’t say I ever felt like my GSC-10 ever slowed me down any. And one negative thing about the new individual sensors is that the speed sensor can’t be used with a disc wheel. I at first thought that I would be able to put it on my front hub instead but my race wheel front hub is not thick enough for the strap that is provided. I suppose if I really cared I could find a DIY solution to that.
Just looking for a cleaner look. Would throw the gsc10 on the mountain bike.
the cadence piece goes on the inside of your crank arm - so it is still “in the wind” a little as you come over the top. the speed sensor goes on your hub.
I upgraded to these when I got my 520 a month of so ago. I love that they are magnet-less. I only use the speed sensor when on the trainer. (I know, useless data, but it gives me some constancy to myself atleast)
I don’t use the speed sensor when riding on the roads. I rely on the GPS for speed. I heard the hub based unit (wich works "fine"on the trainer) is more accurate than the GPS?
Anyone out there have more experience than I do???
Wish I could help more than saying it’s worth it for getting rid of magnets alone!
Good luck!

Either the GSC-10 or the new hub based speed measurement will have a more accurate instantaneous reading than on based on GPS. Obviously speed is a measure of how far you move in a given period of time. For short periods of time GPS based speed has to be calculated by seeing how far you travel in that short time. The shorter the period of time the more impact the accuracy of the GPS has on the speed calculation. So for example., if your GPS accuracy is 10m (I’ve seen much worse on occasion!), and if your time interval is 5 seconds (I don’t know what it really is). Then the distance between your recorded location at the start and end of a 5 second window even if you don’t move is potentially 20m which is a recorded velocity of 4m/s or 14.4km/h (9mph) without any real movement having occured. If you are moving that variation would be added to your velocity so your speed will be seen to increase/decrease and/or the direction of travel will be distorted. In reality chances are this worst case variation won’t occur and the time window may be incorrect, (there may also be some built-in error reduction algorithms) but I presume this is why cycling and especially running/swimming pace readings from GPS are often either way out or very slow to respond depending on the device.
Anyone notice that the hub-based speed sensor sometimes takes a little while to “wake up”?
I can only get it to pair with my 810, and for that it does take a little bit for it to wake up. I’ve never been able to get it to pair with my 910 unfortunately – can’t figure out why, but have since given up.
I use it with my Garmin 810. I put it on the hub of my trainer wheel and use it for speed only. Use my Quarq for cadence. Works perfect for that. That way it doesn’t matter if I’m on my TT bike or road bike on the trainer. Plus, nothing strapped to the chainstay as the zipp ties always would scratch them…

I will upgrade when my gsc10 dies. Downside for race day - can’t use the new speed sensor with a disc wheel.

Use a piece of strong double-sided tape plus a shorter rubber band. Perhaps an O-ring for mounting the Garmin 500/510/520 would work.

I use a front and rear disc. I only race on calm days. 
You are correct. Downside is multiple wheels and not having data on trainer. From what I can gather, it isn’t the toughest thing to move though.
Nope, it’s really easy. It’s just an elastic band that wraps around the hub and hooks on.

Thanks!
I had the GSC 10 on all my bikes, whilst accurate I did find it sometimes got knocked which meant it was too far from the speed or the pedal magnet so I would often find that the speed was working but cadence wasn’t and vice versa.
I have nowupgraded to the new Garmin sensors and I can tell you they are x10 better than the GSC 10 - I have upgraded all 3 bikes to the new sensors.
Also I thought the GSC 10 looked rather ugly, the new sensors are much more subtle, hidden and therefore more aesthetically pleasing.
Finally you should forget using GPS for speed on a bike - it is dreadful, the speed bounces around a lot - makes it very hard to maintain a nice steady speed when riding at the front of a group.
Upgrade today from the GSC 10, you won’t regret it!
Super easy, I swap between men tri bike and CX bike that’s on the trainer constantly. Like others, I like seeing speed on the trainer since I don’t have a power meter or a smart trainer, I get to see some consistency on training without memorizing gear selection. I worry the elastic band may wear out from moving it a few times a weeks, but it’s cheap to replace. It does drop signal for very very short instances sometimes and my unit will read zero, but it isn’t often and hasn’t hurt an outdoor ride for sure. I never had the chainstayr mounted system, but I’m much more comfortable with this compared to zip tying to the chainstay
I ended up purchasing the Hub mounted sensor with cadence. You are right the gsc10 when mounted in the chainstay I had to angle it outward to be able to pick up my cadence. That is basically I wanted to change.

I noticed that for the speed sensor to wake up quickly (with two or three turns of the wheel), the wheel needs to be turned not too slow, but also not too fast. Walking speed works best.

Can one use the new sensor on a wheel with a disc cover? Just put it on before you install the cover? If not, how does one use the GSC 10 on a disc or disc cover? I was thinking of a wheel builder cover for my 404 and didn’t think about the magnet until I read this post.
