Today I bought a 2nd hand Wahoo Kickr core (2021) and had also purchased yesterday a Zwift Click on its own from Zwift UK. Updating the Kickr firmware via the Wahoo app was simplicity itself on my Samsung A34 and the Zwift Click was identified with the Zwift companion app. My Wahoo cadence sensor was also picked up. I used my Shimano 10/34 Cassette on the Kickr and lined up a mid gear with my 50 tooth crank gear. Immediately on starting Zwift on my Lenovo laptop everything worked perfectly including my Garmin heart rate monitor. I was expecting some hassle with the connections but it didn't happen! The riding sensation with the virtual shifting is superb and the whole system is silent! If you have a Kickr Core buy the Zwift Click and transform your indoor cycling experience.

Thank you for your quick reply. I will watch it again

Thanks for the review. I watched it as I also experienced the zwift cog making some amplified noise especially at higher cadence with low power output. Good to know it’s not bad alignment on my part.

Hmmm....I swapped my 1x11 gravel bike setup for the Zwift Cog Upgrade kit, and my experience has been very satisfactory. Having the extra gears with closer ratio spacing is great for me (~1 - 1.2 W/kg, 80-90 rpm), and I found the cog to be as quiet or quieter than my 11-speed cassette (waxed chain and spot on alignment). Thanks for your review and all the great info!

I’m gonna buy this ASAP, I’m still using the first gen kickr that I’ve had for 8 years lol. The first Gen Kickr refuses to die but it’s inaccurate and now I can use any of my bikes on this hub.

Also, since you don't really need the Hub One hub/cog device for virtual shifting, just a wireless controller and a firmware update, it actually makes sense for people who regularly also use other virtual riding platforms and not just Zwift to stick with their existing cassette when using virtual shifting in Zwift. This way they can still shift normally on the other platforms, at least until they offer virtual shifting too, at which point there's really no reason to keep regular cassettes installed on a trainer that does virtual shifting. You also don't need the Hub One hub/cog device for multi-bike households so long as you're only looking to ride in Zwift with virtual shifting, and at most will have to trim the driveline when swapping bikes, as you only need to be on one cog in VS mode.

I had a wahoo kikr 18 and this thing feels better and smoother than that. The 18 broke, and this feels much better to me than that old kikr. It's not as stable as the kikr though and I fell over with the climb attached and broke my derailer hanger. But it's still cheaper than the kikr even with a broken derailer, and the virtual shifting probably is easier on the bike components as long as you don't fall over.

I want virtual shifting so bad! Zwift, please bring this to the Tacx Neo! 🙏

Thank you very much for the review. When you compared the noise between 11speed cassette and zwift cog, the derailleur seems to be not placed similarly. Could it be that the bigger noise (when using the cog) come from friction between the chain and the rear cage derailleur? Thanks!

it better come to my Kickr

Thanks for the review. Your recording of the sound really peeked my interest. So to reduce the noise, is it possible to swap out the original sprocket for one that matches your chain, like if you have an 11spd cassette usually, take a similar sized sprocket from that cassette and swap it into the unit instead?

I asked this on Shanes channel as well and hope either one of ya could answer this for me... "random question for ya... So I don't use zwift for indoor rides, i just use my Garmin Edge 1040 to do indoor training rides. Will the "click" pair with the edge in order to gear change on virtual rides or is this hardware only compatible with zwift for the time being? Thanks, love the content!"

And I bought Hub One few weeks ago :( Kickr Core it seems better in every way, but Hub One has one slight advantage, at least for bigger riders. Stated max rider weight for Hub is 120kg, for Core is 113. Since I'm around 110ish, it gives me some solace that Hub has more wiggle room. Great video as usual, Des!

Just to make sure, in virtual shifting as you shift up or down, the resistance gets harder or easier but the virtual speed also gets faster or slower, proportionately, so you get the exact same effect that actual gear shifting would give you and in terms of feel it's effectively the same, right? Also, any idea why a freehub is part of the Hub One mechanism and it isn't just a one cog "cassette" with equal sized spacers on either side that you could could swap out for a regular cassette? Because Wahoo and Zwift are saying that you can't upgrade a Core the way you can upgrade a Hub to be a One, because it involves swapping out the actual freehub, which makes no sense.

So my take on Zwift ONE vs CORE is basically: single cog vs cassette and zwift click vs manual. As for ERG mode with something like TR, both options work the same, correct?

Please help: 1)The hub one is rated for between 19°F and 77°F. Is this comparable with all trainers? 2) while using hub one, and the click, erroneous speed values are reported to my Garmin head unit of over 100 miles an hour. does the kicker core one have this problem as well?

what's the range of rear gears - I'm using a 11-34T what's this one do please ?

Great review! The hub is disappointingly noisy.

Hi , if I buy Wahoo Kickr Core Zwift One can I use cassette in the future ?

Can I use the virtual shifting o LEVEL (basic) mode? Meaning when doing my own workout.

Can you use the zwift click to shift if I am controlling my kickr v6 with my garmin edge?

I will definitely not be upgrading my Kickr to the hub. Increase in noise is significant.

I have got to buy a new Kickr because my $1300 Kickr is worn out. I am going to buy the Core but I do not want the Hub. My question is will virtual shifting work with a cassette if you leave it in the middle gear.once you download the firmware

If I just want to use the click with my casette for virtual shifting on my 11 speed what is a good place to leave the front and back gears ?

Will they update it to work with the kickr v6?

Does this mean we can use it on single speeds?

Do you know whether the Zwift Click will be available WITHOUT the cog for those of us happy to use the full drive train?

I wonder if this could work with a Tacx Flux 2 or only with a Wahoo?

Does anyone know if it will work with other SMART interactive systems so your not locked into a subscription after 12 months.

Looks like zwift and wahoo settled things 😂

I can use my Zwift controller with my current cassette to change gears?!?!?

Seems u have got a faulty kickr core. it makes some high pitch noise all the time. But my new one did this also and some additional things. I got the 3 units now and they all do almost the same annoying sound with some differences. Wahoo says its normal. In many older videos u cant literally hear anyhting. But there are also tons of known probs with this trainer published. I guess Wahoo just gave up with this product. I went for the Zwift Hub One even its discontionued. U cant hear anything except the chain. Its just a little less stable because of the lower weight.

Why are you in the little ring?

If you only need the clicker or play controllers, why can't they just update the companion app and let us use it without buying more plastic kit? Surely that would make sense. Maybe make it an in-app purchase or something. Better still, make it purchasable with drops!

Looking good, drop your heal. Just kidding.

Sounds like a worn-out drivetrain

I have the kickr 6 called zwift they said it would work it does not even fit it will be more than a firmware update someone needs to get facts right
