Thru-axel wont fit Kickr V6 with Cog V2 on Shimano HG Freehub

Hello!

I just received my brand new Zwift Ride and I’m putting everything together but I’m unable to get the through axle to screw into the other side. I’ve attempted to screw it in without the kicker involved to see if it will work and the through axle just spins. I’m able to screw it in on the opposite side so that leads me to believe the through axle is fine but what receives the axle is not. I’ve noticed other people have had this issue but I’m not really seeing any solutions.

Does anyone have any recommendations? I’ve reached out to support via email but have not heard back.

Thanks in advance to anyone who has suggestions/advice !!

Just a random observation from the photo – the thru axle needs to be pushed a lot further in before it will screw in.

Take the frame off the trainer and see if you can install the thru-axle when the trainer is not present

I don’t know about the Zwift Ride, but don’t thru axles typically get inserted from the non-drive side?

Yeah it looks backwards to me

Zwift Ride thru-axle is inserted on the drive side. It should be tested without the trainer and adapters checked.

Thanks for the numerous replies. I’ll try to explain the problem in more detail. As already correctly mentioned, the Zwift Ride has the thread on the non-drive side. All other bikes are built the other way around, so I’ve never had this problem. The thru axle doesn’t go through the freehub without the Zwift Ride. Only the thread fits through the nut. I mounted my Zwift Ride on a Shimano HG freehub. I don’t know what’s wrong with it, but I’m grateful for all the answers.

Hello, unfortunately not, and that’s my problem too. Because all the other bikes I’ve mounted on the trainer so far have been mounted from the other side. I also tried pushing a thru axle from a regular bike through the freewheel “upside down,” but that also gets stuck pretty quickly.

Well that is odd, it looks like you can slide the thru-axle all the way through the trainer from the left side, but the same thru-axle gets stuck when you try to insert it through the trainer from the right side. Am I understanding that correctly?

Yes, that’s correct. If you push it through from the right, it only slides in to the end of the thread. After that, it’s stuck and can’t be pushed in any further.

The problem is not the last adapter but the nut that fixes the freewheel

The thing in your hand is the spin cap. It looks like you have the updated verison of the adapters: https://support.wahoofitness.com/hc/en-us/articles/360018850859-Updated-KICKR-CORE-thru-axle-adapter-installation

The fact that the thru-axle passes all the way through from one side but not the other is strange, it makes me think there is some kind of misalignment. Are you using the original Wahoo freehub that came with the trainer, or is it the Zwift multi-trainer freehub that is sold with the Cog? It should not matter as they are intended to be interchangeable. I’m assuming you can successfully slide that spin cap over the thru-axle from either direction.

By the way, it does sometimes require some force to snap the spin cap in place. Mine went on easily but I’ve heard from others with a different experience

I’ve now spent a bit more time playing around with it and solved the problem.

As you already mentioned, contrary to my logic, you have to use force. Using grease and a rubber hammer, the axle slipped through. Thanks in any case for the quick replies – it’s a really great community. However, I don’t quite understand why the Zwift frame’s axle mount has to be constructed differently than conventional bicycles. Then no force would have been necessary.

Yes every used component is original Wahoo or Zwift.

I think your experience is not the intended one. Everything went together smoothly with mine, no force required. I’m not sure what was going on.

So I’ve bought a Zwift Ride and the Thru Axle does not tighten into the thread on the non-driver side. Tried all tricks, nothing works.

I guess I’ll either need another axle or another frame. I’ve sent support an email over 24h ago and haven’t gotten a response.

I must say this is quite a horrendous experience for someone who just wanted to have a way to train indoors. I’ve paid a lot of money to have a nonfunctional bike and now can’t seem to talk to anyone in person to solve the problem.

Is there any other way to contact Zwift or do I just need to wait on an email that will hopefully offer a solution? What is the average response time for them?

I agree that they are slow to respond but your issue is most likely user error, wrong drive side adaptor, wrong non drive side end cap or wrong install of the cog

this thread might help, same issue I think

The cog is pre-installed, double checked the Kickr installation, everything done by the book. And it also doesn’t tighten when it’s not on the Kickr Core but just the frame on its own.

I kind of hope it is my fault to not have to go through all of this hassle but I don’t see how it could still be my fault with all I’ve tried.
