Hey all,
Just upgraded to a Tacx Flux S from my older Renpho Bike, wondering if there’s a possibility to purchase and install a Zwift cog on the Flux S, and be able to use the single cog / virtual shifting?
Thanks!
Zwift doesn’t support virtual shifting (yet) on any Garmin/Tacx trainers, so at this time you would need to use the QZ app (qzfitness.com) to get virtual shifting. It would allow you to use the Zwift Click or Play controllers with your trainer, but you’d have to install an additional 3rd party app on a phone or tablet. You could buy the existing Zwift Click+Cog kit, remove the Cog from the freehub it comes with, and install it on the Flux. If that sounds appealing, talk to @Roberto_Viola who wrote the app.

Hi Richard, qz developer here. Let me know if I can help you!
Thanks for the info guys!
I used an iPad to run swift, and my iPhone to run companion. Would the QZ app run alongside those? or does it need to be the primary app running on the device?
Anyone you know if Tacx/Virtual shifting is on the zwift roadmap in the near future? I’m also an AppleWatch HRM guy… so I’m waiting on that too… lol

I’m trying for the last 4 days with the help of Roberto in Italy and still can’t get my click to work.
The click is connect on my companion.
My tacx signal turning wahoo on my pairing but nothing show on control pairing.
Any tips?
Hi Roberto.
I have a question about the compatibility of my tacx flux 2 and the zwift gears.
I’ve seen on the zwift shop that the ride frame isn’t compatibile with tacx trainers, but I don’t understand why…
Tacx Flux works perfectly with the app, the cog fits on the shimano freehub, and the frame controllers work with the app. So the app is the “bridge” of all the devices, and on my opinion they should work toghether.
I would like to buy the Ride Frame or at least the zwift cog with zwift play controllers, but I would like to use my traner. Is it possible?

Hey Roberto!
I’m new to the bike world and just got an tacx flux s as a gift. The zwift cog sounds pretty interesting for me instead of buying the SRAM xdr frehub and 12 force cassette. It only seems to be possible via your app if I get it right. Do I need anything else or am I good to go with the Shimano freehub that’s on the tacx, the zwift cog and your app.
Looking forward to your reply
Julian
Yes you are good to go! Send me a PM for other information, going to bed now

Hello Roberto,
Can you give me some info about your app.
I couldnt find the option to send a pm.
I have a tacx neo 2t trainer and am thinking about getting the zwift smart frame with the zwift cog. As fas as i was reaing your posts with your app that would be possible right?
Hoping to hear from you
