Short answer: Zwift Cog is a single sprocket that replaces the cassette on a smart trainer, and Zwift Click is a pair of small handlebar controllers. Together they give you virtual shifting: the trainer changes resistance to simulate 24 gears, so any 8- to 13-speed bike works without matching cassettes. It suits households sharing one trainer and riders who mostly use Zwift. We sell it built into the JetBlack Victory at ₹59,200, the Wahoo Kickr Core 2 at ₹79,999 and the Elite Avanti at ₹81,990.
"Cog and Click" now appears in the name of many smart trainers, and it is one of the most common things riders ask us about. It changes how a trainer works more than the small parts suggest. This guide explains what each part does, how virtual shifting works, where it helps and where it does not, the differences between the Click versions, and which trainers we sell with it.

What Zwift Cog and Zwift Click are
- Zwift Cog is a single sprocket that fits on the trainer in place of a cassette. Its teeth are shaped so that chains from 8-speed to 13-speed drivetrains run on it, and its position adjusts so the chain lines up with your bike. Your bike's rear derailleur simply holds the chain on it.
- Zwift Click is the controller. The current version is a pair of small wireless units that strap to your handlebar, with buttons for shifting up and down, steering, menus and Ride Ons in Zwift.
Neither does anything on its own. The Cog gives every bike the same single gear on the trainer, and the Click tells the trainer when you want a different virtual gear.
How virtual shifting works
With a normal cassette, changing gear moves the chain to a different sprocket. With Cog and Click, the chain never moves. When you press shift, Zwift tells the trainer to change its resistance as if you had changed gear, and your speed in the game changes to match.
- 24 virtual gears by default, covering roughly the range of a road bike.
- Shifts are silent and instant, and Zwift says they are safe under full load, so you can shift mid-sprint.
- The gear range can be customised, which a fixed cassette cannot do.
- In ERG mode workouts, where the trainer holds a set power, the buttons nudge the workout intensity up or down instead.
Where it helps
- Households sharing one trainer. A road bike, a hybrid and a mountain bike can all go on the same trainer without swapping cassettes, as long as each is 8- to 13-speed.
- No cassette to buy or match. A direct-drive trainer normally needs its own cassette that matches your bike. The Cog removes that cost and the guesswork.
- Less drivetrain wear and noise. The chain stays in one line, so there is no shifting under load on worn parts, and the trainer is quieter.
- Bikes with awkward drivetrains. Riders whose bike shifts poorly, or whose speed count makes cassettes hard to find, still get smooth gearing indoors.
The limitations
- It is built for Zwift. Zwift Click officially works only with the Zwift app. Some other apps have added unofficial support, which can stop working after updates. If you ride mostly on another platform, check before relying on virtual shifting.
- 7-speed bikes are outside the range. Zwift lists the Cog for 8- to 13-speed drivetrains. Older 7-speed chains are wider and may not run smoothly on it.
- Controller placement. The Click units strap to the bars, and on drop bars they are not quite where your thumbs naturally rest. It takes a few rides to get used to.
- You can still use normal gears if you prefer. Most trainers sold with the Cog can take a regular cassette instead, but the cassette is then a separate purchase.
Click v1, Click v2 and Zwift Play
| Zwift Click v1 | Zwift Click v2 | Zwift Play | |
|---|---|---|---|
| Form | One small unit | A pair of small units, one per side of the bar | A pair of larger controllers that sit on drop-bar hoods |
| Does | Shifting only | Shifting, steering, menus, four action buttons | Shifting, steering, menus and more |
| Bars | Any | Flat, aero or drop bars | Drop bars |
| Power | Coin cell | Replaceable CR2032 coin cells | Rechargeable |
Zwift launched Click v2 in September 2025 and says it replaces both the original Click and the Play controllers. Trainer bundles made before then came with Click v1, so depending on when a bundle was packed, it may contain either version. Both handle virtual shifting; v2 adds steering and in-game controls.

Setting it up
- Fit the bike. Remove your rear wheel and mount the bike with the chain on the Cog, using the right axle adapter for your frame.
- Line up the chain. Use the front chainring that gives the straightest chain to the Cog, and adjust the Cog's position if the chain runs at an angle or rubs.
- Leave your gears alone. Once set, you do not use the bike's shifters on the trainer.
- Mount the Click units where your thumbs can reach them: on drop bars, on the inside of the hoods works for most riders.
- Update firmware on the trainer and the Click through the maker's app and the Zwift Companion app.
- Pair in order. In Zwift, connect the trainer first, then the Click controllers, and set their orientation so steering works the right way round.

FAQ
Does Zwift Cog work with a 7-speed bike?
Zwift lists the Cog for 8- to 13-speed drivetrains, so a 7-speed bike is outside its official range, because older 7-speed chains are wider and may not sit and run smoothly on a sprocket shaped for narrower chains, and Zwift does not support that combination. Some riders report it working, but it is not guaranteed. If your bike is 7-speed, the safer option is a trainer fitted with a standard cassette that matches your drivetrain, or a chain upgrade if your bike allows it.
Which Zwift Click comes in the box, v1 or v2?
It depends on when the trainer bundle was packed, because Zwift replaced the original single Click with the two-piece Click v2 in September 2025, and bundles made before then shipped with the older version, while newer bundles carry v2 in its place. Both do virtual shifting with the Cog. The v2 adds steering, menu navigation and action buttons in Zwift. If the version matters to you, ask us before ordering.
Can I use virtual shifting in apps other than Zwift?
Officially no, because Zwift designs Click and its virtual shifting to work with the Zwift app, although some other platforms have added unofficial support for Click controllers that can work well but may break after an app or firmware update. In ERG-mode workouts on any app, gears do not matter, because the trainer holds the target power whatever gear you are in. If you mainly ride another app, a trainer with a normal cassette may suit you better.
Can I fit a normal cassette instead of the Cog later?
On most trainers sold with the Cog, yes, because the Cog sits on a standard freehub body that also accepts a regular cassette, so you can switch to real gears if you change apps or prefer shifting with your bike's own levers. The cassette is a separate purchase, and it needs to match your bike's number of speeds. Check that the trainer's freehub suits your cassette, such as Shimano HG for most road bikes.
Do I need a separate Click if I already have a Zwift Play?
No, because Zwift Play controllers can control virtual shifting with the Cog in exactly the same way as Click, so a rider who already owns a pair of Play controllers only needs a trainer with the Cog fitted to start shifting virtually. Play sits on drop-bar hoods and is rechargeable, while Click v2 is smaller, uses coin cells and also fits flat and aero bars. Either works, so choose by your bars and preference.
Choosing yours
The right trainer depends on your bike's drivetrain, the apps you ride and who else will use it. Ask TBA Guide with your bike and the apps you use, and we will suggest the trainer that fits.
