ZWIFT COG V2 Full Details // COG V1 Comparison // Sound Check // Q & A

[@ginomordocco4710]

If you have a Shimano 14 tooth from a cassette laying around you can use it on the V1 cog and it makes a HUGE difference in sound. No need to get the V1.05 or V2.

[@Neil_down_south]

I wonder what's different about the Shimano sprocket that changes the sound?

[@aarons1073]

I bought a 14T single speed conversion kit that includes an assortment of spacers to adjust the chainline where you want it. It's wayyyyyyy quieter than the Zwift Cogs, probably because it doesn't have the plastic echo chamber surrounding the cog itself. The only downside is it takes a bit more work if you want to adjust the chainline from bike to bike. The significant noise reduction is nice though.

[@richardhill2836]

Do you mind telling me where you purchased the conversion from? Thanks!

[@HabaneroTi]

What's the point of swapping a perfectly fine cassette for the Cog or a single speed kit, unless you only have one good cassette and don't want to keep swapping it between the trainer and rear wheel if you ride both indoors and out? In fact, even if you only have one good cassette you can probably use one of your bad ones, that are worn and skip, because almost certainly there's at least one good cog on it and you can use that in VS mode and Zwift takes care of the rest. Of course if it's the biggest or smallest you'll wear out your chain faster. But you can just move it closer to the center by removing bad cogs and replacing them with spacers.

[@davidrowe8747]

I think your point regarding ride "feel" is important, and rarely mentioned. People often compliment virtual shifting because it is so smooth, but that's also a potential negative. When you use real gears, not only do you feel the gear changes (often a negative if it's a clunky shift - or you throw a chain!), but riding small/large (uphill) vs. large/small (sprinting) has a very different feel that you just don't capture with virtual gearing because you are always in 42T/14T. Even the change of gear doesn't feel "real" - when you go down or up a mechanical cog, you feel it and hear it, but shifting a virtual gear, there's nothing to hear and often, very little to "feel". Not a huge negative, but I imagine for serious riders training for the outdoor season, it could be a bigger factor in choosing whether to go virtual.

[@MrZiggenpuss]

Just purchased a wahoo kickr with v2 cog pre-installed, first attempt last night another go shortly. But this was one of the immediate things that threw me, missing that change/feel of real gears.

[@HabaneroTi]

A gear ratio is a gear ratio and all other things being equal the resistance felt at a given cadence for a given virtual terrain should be the same whether it's a "real" gear combo or a virtual one. In a sense there are three "cogs" when you use virtual shifting, the front chain ring and rear cog, and the virtual one within the trainer that "shifts" up or down to get the desired gear ratio. So what does it matter what the first two are so long as the third one dials you in just right? Feels the same.

[@davidrowe8747]

@@HabaneroTi have to agree to disagree as in my experience, virtual shifting has a completely different feel from mechanical shifting. And is certainly less noisy so has less auditory feedback.

[@edray5217]

As far as I can tell this, like any single speed adapter kit this would effectively transform any combination of outdoor bike and compatible Turbo Trainer into a Stationary Smart bike such as those from Wahoo, Tacx, Wattbike, Stages , albeit without any electronics built into the handlebars, as is also the case with Zwift's "Ride" frame. As others have noted, with virtual shifting it is actually possible to use one cog on your existing cassette for "simulated" gear changes, though this would only be suitable for the bike it belonged to, unless others shared a very similar chain width!

[@scourbase]

My Zwift Ride (bought in August 2024) came with a (updated?) V1 cog.

[@jeremykemp3782]

Mine the same, and I purchased last month. The v2 is if you are using different frames in the household where the free adjustments would be useful I think. The updated v1 is perfect as it is WITH the zwift frame that is

[@markojarvenpaa2486]

For me it was definitely an improvement to go from the original Cog V1 (at least I think so - bought kickr core back in April 2024) - to Cog V2 when I got my Zwift Ride Frame. Cog V1 on Zwift Ride was really noisy when compared to the previous installation when I had the trainer attached to my road bike.

I have run 7, 11, 12 and now my new rotor 13s with wheeltop eds Tx system on my H1 or original hammer trainer.

[@wullxz]

A constructive feedback: That sound comparison was well done conceptually. If you say nothing when the sound changes to the next item or just something brief like "next one", it's easier to compare in all detail. The first two cogs were such a massive difference that you probably could've read the complete series of Lord of the Rings between and we still would know that it's a difference. It was hard to tell apart the specific aspects of the sounds created by V1.5 and V2 though. Apart from that: keep up the good work and great quality of your videos. I've watched a lot of your videos because of my newly bought Garmin products and they helped a ton!

Good to know that it only works on thru axle frames. My current trainer bike is a QR style frame, so will stick with the cassette. It looks like you could mostly replicate this by just replacing your cassette with a 14t single speed cog and spacers, like you would for a single speed conversion.

[@_Old_Andy]

Cheers for that Shane. Are you planning on doing a review of the Jet Black Victory?

[@C.Connell78]

Shane, I believe there is currently a pretty significant hardware issue - but I'm not sure if it's the COG V2, Kickr v6, or some combination therein. I recently became intrigued by another KZbin Zwifter's livestream, where he was accused of cheating. This had to do with the rider getting "free watts", but there was a lot of back and forth. Well, I typically dual record my rides, but I had taken my power pedals (Assiomo Duals) and moved them to a different bike. However, I started to notice that when coasting in-game, my RPMs appeared to be inaccurate. Given I race, I swapped out my pedals - and I'm seeing power discrepancy that I had never noticed, prior to running Zwift Play, Cog v2, and the Kickr v6. If this is an issue, it is likely impacting more than a few people. Given your knowledge and in-depth reviews, I thought I'd try to raise the potential issue here.

[@gplama]

Was this being called ‘Sticky Watts’? In regard to power accuracy, using the Cog is no different to using a 14t on a standard cassette. There are a few edge cases where smart trainers will over/under report, usually related to flywheel speed.

[@ekalvi]

It's not sticky watts. Zwift has confirmed there is an issue with the combo of kickr V6/core, virtual shifting and their auto calibration. Essentially once auto calibration happens, the trainer can overreport watts by varying amounts much greater than 2%. I know because it's happening to me and I've done a bunch of dual recording and can recreate with multiple Assioma pedals as a reference

[@C.Connell78]

@@gplama no, I believe this is different. I really encourage you to look at this. There is an active thread in the forums - "virtual shifting, free watts". Wahoo and Zwift have acknowledged, but have published little. They have apparently told the pros to avoid using this setup - a setup the rest of us are actively purchasing. I have dual recordings to support the issue. I have a Kickr v6, updated firmware, and cog v2. It is not effecting all people. I am getting a 10-15% performance benefit, across the board. Wahoo has stated they are coming out with firmware to address, but current workaround is factory spin down. I just don't think it's right that this is going on.

[@C.Connell78]

@@ekalvi likewise

[@C.Connell78]

@@gplama if you do have interest in replicating the problem, many believe that the Kickr auto calibration in high virtual gears (22-24) acts as a potential trigger.

[@davidrowe8747]

Another very insightful video, Shane, thank you - the Cogs are much more simply constructed than you'd think! Just a piece of information that might be useful - the Cog has 14T and the Zwift Ride chainring has 42T, for a gear ratio of 3.0. I'm towards the end of a 6-month journey with Zwift Support trying to resolve an "erratic resistance" issue with virtual gearing that appears to be related to gear ratio. Early recommendations when the Click came out were to use the small chainring on your own bike, and the straightest chain line, which on many bikes (especially 2x set-ups) results in quite a low gear ratio, closer to 1.5. Since moving onto my larger chainring and a smaller cassette cog, replicating the Ride's 3.0 gear ratio, these issues appear (so far) to be resolved. Bottom line is that if people are using their own bikes, resistance issues may be resolved by setting their gearing to a larger gear ratio, ideally close to 3.0 - or at least switching to the larger chainring.

Really wanted to get the cog and the frame but my 2018 kickr isn't supported and works perfectly so not worth buying a new kickr core for it as well. Shame only the new kickr is supported for this.

[@ShadLife]

I just got a whole new trainer setup. I wanted virtual shifting so I replaced my Kickr v5 to a Kickr v6. I also ordered this Zwift Cog V2. I have a GRX 810 2x drivetrain. It seems I can only get a good alignment if I am in the small front ring (even at the 10th click over). I could not get the cog alignment in the large ring up front. To me it feels like the gearing is too easy. When I am at 0% grade I can easily pedal in the virtual 24th gear. 2 questions. 1, does the gear ratio of the bike matter (which front cog I am in)? 2, do I have to do some sort of spindown (which it says I don't have to do) in order to get the trainer to have the correct resistance per gear? Also, could I remove the Zwift Cog from the cassette and space it out more so I can line up the big ring if that would resolve the issue?

[@gplama]

Zwift say there's an auto-chainring detection process as each session starts to ensure you're given the equivalent resistance per gear regardless of what size chainring you're using. I'll dig into this one day with my MTB (32T chainring) vs gravel bike 42T.

[@ShadLife]

​​​@@gplama FYI. I did a route today and things seemed to work more sensibly now. When on the flats I was in gear 15 or 16 mostly. For 4 and 5ish percent grades I would virtual shift to 12 or 13. My RPMs seemed normal for how the resistance felt. So all seems good. I used Race Mode also and it was much nicer on rolling hills and such where my watts would power up much more quickly. I got higher average watts on my route and I assume that's because it's more accurate to my effort with a more responsive trainer. My guess is that when I tried it immediately after assembling the Zwift Cog and setting up the trainer it just took some time to calibrate and work right.

I wouldn't be holding your breath for it. It remains unknown if they have any tech staff who could implement this after the company was sold. They appear to have resurrected their social media accounts at this point. There's also issues in trying to get the 14T cog working with smart trainer resistance units that were never designed for use with virtual shifting. Wahoo were lucky the CORE was able to achieve this.

[@zacharykuhns6060]

@gplama bummer, oh well.

[@davidpatterson5313]

Hi, Thanks for very informative videos on indoor trainers and alike. I'm a bit confused though. I am in England and Looking to but a wahoo kickr core Zwift one. But I've emailed zwift just before checkout as there is no mention of a 1 year free subscription. Zwift say it is included in the price but there's no mention through checkout. So I messaged wahoo and they say you have to add it at checkout and it's a discounted £130 so total price is £579.99 which is not what the bundle says. Do you have any info on this? Have the bundle been dropped??

[@SenaR88]

Hi, what real gear on my di2 11 speed transmisson сompatible with V2 cog?

[@gplama]

It's somewhere in the middle of the range. Install your bike, click through the rear gears until it lines up nicely, use the adjustment on the COG to do any smaller adjustment as required.

[@1mhk]

Can I use it on a old bike with QR?

[@gplama]

Yep. As long as the trainer has the right adapters.

[@Mooza1]

When released in Australia?

[@Eirikkinserdal]

with elite putting it on the direto, do you think they will put it on all their trainers down the road?

[@gplama]

Unsure.

[@Eirikkinserdal]

They should though. Same with wahoo for the v5 as it's not any dumber than the kickr core 😂

[@HabaneroTi]

If you only intend to ride on Zwift indoors, or in ERG or single gear mode on other platforms, then this is a viable alternative to a cassette. But if you intend to ride in sim mode on other platforms, want to be able to shift gears to match the terrain and cadence, and don't want to mess with 3rd party apps, then you need a cassette because at present no other platform offers native virtual shifting. Which makes me think that one of the main purposes of the Cog is to lock most people into Zwift. Which is their right, of course, but people should be aware of this before committing. Of course even if you only have the Cog you can always install a cassette and it doesn't have to be high end because weight isn't a factor.

[@gplama]

Covered in-depth in my other videos on the Cog/Virtual Shifting.

[@randomdude5938]

Does anyone know if you can replace the cog with a gates belt drive cog? I’d love to have a belt drive for by indoor trainer. So clean and quiet.

[@SimoneChiaretta]

Still annoyed that wahoo didn’t add virtual shifting on kickr v5

[@haydenmcdonald8260]

When does cog 2 come out in Australia??

[@gplama]

Zwift Click and Cog v2 upgrade kits are on the Wahoo AU website.

[@renedavila5900]

Shane, thank you for consistently keeping us updated with this information… I have a Garmin Tacx Neo 2t, and I am researching the Zwift bike frame. Though, as far as I understood, I can’t use this frame with my Neo 2T, the issue relays on the virtual shifting since the frame uses the Cog instead of a cassette. However, there is an app named as QZ which will work as a bridge between the neo and the Zwift play controls over ant connection to do the virtual shifting on Neo 2t… I have not tried myself. Do you know if this is accurate?, is there any hope from Garmin to have this in the near future?. Thanks in advance for your feedback.

[@gplama]

Garmin/Tacx do not officially support Zwift Protocol for virtual shifting, so there's no easy/native/supported way of using the Zwift Ride frame on any Garmin/Tacx smart trainer at this point in time. Garmin will not give any insight into future products or plans, so we don't know what they're working on. What we do know is they're slowly fading away from the conversation by not offering any new products other than the 3M (US$2000) with less features than the upcoming JetBlack Victory (US$399). RE: QZ. I'm planning on digging into this but my spidey senses are pinging that it's not going to be an optimal working solution for virtual shifting. It also adds another layer of complexity. I'll know more on this once I've had a chance to test and compare it to the native Zwift Protocol style of virtual shifting.

[@pavlej91]

Hi Shane, thanks for the great overview. Is the Cog compatible with Elite Avanti? Couldn’t find any info online. Also, any chance you are planning to review Avanti?

[@gplama]

No compatibility with the Avanti. I’ll do a review if I can get a production unit to test.

[@marccale9890]

Hello! Great video as ever. I take it if you're using a quick release bike, the comment about the 142 mm Thru-axle set-up doesn't apply?

[@gplama]

If you’re using a bike with quick release then it isn’t the Zwift Ride, so you’ll need to use the QR adapters.

[@marccale9890]

​@@gplamathanks...yeah sorry. Bit of a dumb question. I blame tiredness 😂

[@cameronurquhart1515]

Hi Shane do you know whether the Zwift COG V2 will fit the Kickr Core (2019 vintage). I have updated the firmware but after checking the various sites for the COG I'm a little unsure if the COV will be compatible. Thanks in advance

[@gplama]

Yes. 100%. It'll physically fit on and with the updated firmware, Zwift Play or Zwift Click controllers, and pairing via Bluetooth - You'll get virtual shifting.

[@cameronurquhart1515]

Thanks so much. Now just to wait for stock

[@David-r3b7f]

I see you have The Victory are you doing the review any time soon? I ordered mine a few weeks ago looking forward to hear what you think

[@gplama]

Yes. Coming soon.

[@MrMattie725]

Help me think this through: given the small cog which is 'fixed', my flywheel speed would always be quite high at a decent pedalling RPM? I'm running into slippage problems on my Zwift Hub when I need to use the 34 teeth cog on radio tower for example. I assume because generating the required resistance on such low flywheel speed is difficult. I also think higher flywheel speeds might reduce the thermal effect I tend to experience. Intervals sometimes get easier during a workout, especially when I was a bit far up the cassete. I assume due to thermal drift. This one is much less 'provable' than the slippage though. I'm actually considering the Cog V2 as an upgrade this indoor season! :) (Just the Play or buttons for virtual shifting would do the trick if I think about it)

[@davidrowe8747]

It's not just the size of the Cog that's important, it's the overall gear ratio. Zwift Ride chainring is 42T so Zwift Ride gear ratio is 3.0 (42T/14T). Even when virtual gear changes, the relationship between pedal rpm and flywheel revolutions/speed is constant. Using virtual gearing, I have had very bad problems with what you call "slippage" (pedal revolutions suddenly slipping?) and after 6 months working with Zwift Support, it's beginning to look like gear ratio is a factor - that when gear ratio is closer to 1.0, resistance is very erratic, primarily on steeper climbs. As you say, you don't really need the Cog, just the Play or Click controllers. If you do this, put your chain on the larger chainring and try to replicate a gear ration closer to 3.0, to see if this works optimally.

[@MrMattie725]

@@davidrowe8747 Given my current setup, I would have a 50/17 ratio with a straight chain using the middle of the cassette. The slippage feels indeed like suddenly losing resistance. As if my backwheel is slipping through some mud whilst I push down on a pedals. I only have this issue in the small chainring and biggest cogs, which gets below a 1:1.3 ratio. So I might consider the Play as this might solve the issue with the added game features. Kind of sad that you need extra hardware to unlock purely software features but that's business I guess.

[@kylepazandak5578]

Belt drive eventually?

[@6ft8incyclist]

Belt drives rob power

[@kylepazandak5578]

@@6ft8incyclist I love em, darn near silent, no maintenance, no oil, etc. gladly take that when it’s “robs power” is for pushing a fake bike in fake game.

[@6ft8incyclist]

Fully agree. Did not know if you was a racer on ZWIFT. Along as I can stay with the Club/Event rides I will be happy. I asked Mr Lama the first Single cog video he was the one that told me about losing power. If you do it please let us know how it goes.

[@ace_oneseven]

On the Zwift Shop there are 2 Versions of V2 Cog: -> Freehub Type: Multi-Trainer -> Freehub Type: No Freehub i dont understand this, i would buy a Cog for the Decathlon Ride D100. Can anyaone help?

[@hutzell73]

I just recently installed the Cog V2. I like it and it wasn't hard to install and set up. It's a little noisy IMHO.

[@StuartLynne]

Any news on Virtual Shifting for Kicker v5? Then I would need one of these :-)

[@gplama]

Wahoo have said it now won’t be coming to the Kickr 5.

[@Chabowski1]

My Chain is jumping when I go over 300watt. Does anybody know what this could cause? I have the cog installed to a SRAM Chain. I have no idea why this is happening
