About Virtual Shifting

With virtual shifting, your chain doesn’t move between different rear cassette cogs when you shift. Instead, a virtual shift changes the resistance of your smart trainer so it feels like you’ve changed cogs. This is how smart bikes like the Wahoo KICKR Bike, Wattbike, StagesBike, and Tacx NEO Bike have always worked.

Why do Zwifters like virtual shifting? Because it beats mechanical shifting in several ways:

• Fast, smooth, quiet: with no chains skipping between cogs, your shifts are completely silent, perfectly smooth, and lightning-fast.
• Less wear and tear: your chain won’t wear out as quickly, and neither will the Zwift Cog, since it is built beefy because weight is not a concern.
• Shift under full load: no need to ease off the pedals when shifting under power, as your chain isn’t going to “skip” when virtual shifting like it can with mechanical shifting.
• Compatible across many bikes: no more spinning out on your low-geared mountain bike, or needing to swap cassettes if you swap bikes. Virtual shifting works with almost any 8-12 speed bike and auto-calibrates to your physical gearing.
• No more fine-tuning: many riders have to fine-tune their physical shifting when moving between outdoor riding and a direct-drive trainer, since the cassettes aren’t lined up exactly the same. The Zwift Cog doesn’t require any such fine-tuning… just shift to a physical gear that has your chain lined up straight on the Cog and you’re ready to ride.
• Expanded gear range: Zwift’s virtual shifting currently supports a virtual 24-speed setup, which is more gears than most riders have on their outdoor setups. Additionally, the gear ratio range is very wide (from .75 to 5.49), meaning everyone should find that virtual shifting offers more easy gears and more hard gears than your mechanical gearing.
• In-game visualization: with Zwift’s virtual shifting, you can always see what gear you’re in on screen.

Zwift’s virtual shifting was rolled out to the Zwift Hub in late 2023, and it’s arguably the most significant technological advance we’ve seen in smart trainers in years. The CORE One is the first non-Zwift trainer to support virtual shifting, and that’s big, good news for Zwifters.

Depending on your Companion device and Zwifting setup, though, the app’s connection to your active Zwift session may not be stable. This is annoying at the best of times, and race-ending if you’re pairing your devices through Companion!

Several months ago, we published How to Ensure Reliable Companion App Connection when Zwifting. (If you’re having troubles maintaining a steady connection between the game and your Companion app, I highly recommend reading this post.)

Then just a couple of weeks ago, our friend Mike Hanney at Zwiftalizer posted a helpful video with a few more tips that are definitely worth sharing. Watch it below, or scroll down for a summary:

Router Settings

• Turn off 2.4 GHz
• Set up media prioritization (aka “Quality of Service” or “Packing Shaping”)
• Get all your neighbors to turn of 2.4 GHZ as well

Phone Settings

• Turn off Cellular Data for Companion App and/or disable Wi-Fi Assist on your phone overall
• Turn on Device Connection in Companion Settings

Using Zwiftalizer To Troubleshoot Connections

Mike explains how to use Zwiftalizer‘s Connection Attempts chart to determine where in the signal chain your Companion app connection is getting dropped.

Pairing Devices In the Right Order

Zwift’s pairing screen behaves a bit oddly if you’re pairing multiple power sources (for example, a smart trainer and power meter pedals). Mike explains how to pair things up in this situation.

Companion App’s Bluetooth Dropout Device Indicator

If you’re connecting via Companion and have a dropout, the Companion app can tell you which device has dropped out. This information isn’t available anywhere else in Zwift, oddly enough, so Mike explains how to find it.

He also points you to the Trackit app, which can be used to get your signal strength from all your devices.

How It’s Different

Gymrail calls the Momentum X1 a “4D bike rocker system.” Not only does it allow for 15 degrees of side-to-side tilt like a basic rocker plate, it also gives 12cm (4.5″) of fore-aft movement like some advanced rocker plates. On top of that, you also get 12cm (4.5″) of side-to-side sway and 7 degrees of twisting rotation (yaw) from the central axis!

To be clear: “sway” here is your bike being able to slide left and right without tilting. You’ll notice it most when really putting the power down, as the back of your bike slides left and right.

“Yaw” is when your bike twists into a sort of “s-curve”, again seen most when you’re putting down the power, perhaps out of the saddle. As you turn your bars one way, the bike tilts in the opposite direction. (This motion isn’t seen on standard rocker plates, but it is available on the InsideRide E-FLEX Motion System.)

That’s a lot of movement. But maybe there’s something to it. Because any physicist will tell you, the physics of riding a bike are quite complex. There’s a lot of movement going on to keep us upright!

Here’s a quick promo video from Gymrail, so you can see the basics of how the system works:

Unboxing and Setup

The MX1 arrived in a box that had seen better days, but when I unpacked it I quickly realized that nothing was going to break this unit. It’s built like a tank!

The system consists of two separate sections: one connects to your trainer and one connects to your front forks. Both sections require a bit of assembly. Gymrail’s website includes written and video instructions for assembling the unit, and I highly recommend using them.

The rear unit is basically a giant skateboard with added side-to-side sway movement. It comes fully assembled, but you need to mount your trainer securely to it and adjust the bumpers to your liking. To mount the trainer, you first position your trainer where you’d like it on the platform, then screw in the included steel plates beneath the trainer so you can secure the trainer to the platform via the included velcro straps. You’ll need a cordless drill to screw the plates in.

This setup worked swimmingly for the Zwift Hub I was using. The trainer was mounted very solidly thanks to the custom-placed mounts and sturdy velcro straps.

The rear unit includes rubber bumpers underneath which can be slid left and right to change how easily the platform tilts. Adjust these to your liking, but know you can always tweak them later (and probably will). Just get the platform level, then you’re ready to continue.

The front unit just needs the legs folded out and locked in with bolts, then the vertical “steering unit” attached using the included tool. The steering unit has rubber bumpers like the rear unit which you can slide left and right to dampen how easily the front of your bike tilts.

Dialing It In

Assembling the unit is one thing. Dialing it in is another. Without a movement platform of any sort, riders have nothing to adjust. Add a basic left-right tilting rocker plate, and you have the inflation of the balls to adjust (which is no small thing). Add fore-aft movement and you may want to adjust the stiffness (although that’s rarely adjustable).

Add two more types of movement, like the MX1 does, and you’ve got even more to dial in!

The first thing I noticed was that my front forks were too stiff when trying to tilt left and right out of the saddle. So I adjusted the bumpers on the steering unit toward the center, giving that unit maximum freedom to tilt. This helped, although things still felt stiffer than I’d like up front.

(I already had the rear bumpers moved toward the middle for maximum left-right tilting, since I ride rocker plates all the time and am comfortable with that “looser” feel. The rear tilt felt great from the start, so I didn’t need to dial it in further.)

The next thing I noticed was excessive “sway” at the back of my bike when sprinting. Some sway is natural, actually – your rear tire does “slide” left and right in a sprint. But too much sway and you feel like you’re losing power as the rear unit slides left as your right leg pushes down/back, then slides right as your left left pushes down/back. Changing from the installed black springs (the loosest included) to the orange springs (20% stiffer) helped the sway situation.

Here’s a quick video demo I made not long after getting things set up:

Ride Feel

One thing I feel reviewers miss when it comes to rocker plate testing is that you really need to give yourself enough time on a new rocker to ensure you’re actually feeling how it behaves, and not just feeling how it’s different from what you’ve ridden before. I ride with a rocker plate all the time, and have reviewed several rocker plates over the years. Every new rocker feels a bit odd when I start. It takes several rides to really get the feel for how the plate lets me move, and to fully understand if it’s letting me move naturally or inhibiting the movements I’d like to make.

After several weeks of riding with the MX1, I’ve come away with some things I really like about it, and a few things I don’t.

The Good

• It lets my bike move more than any other platform I’ve tested. The rear sway and the s-curve “yaw” are something you don’t get in typical rocker plates, and they really add to the natural feel, especially when seated. The MX1, much like the InsideRide E-FLEX, offers a more natural and comfortable motion than a standard rocker plate when it comes to seated riding at low and mid-power levels.
• Nothing to inflate: inflatable balls can be handy when you’re trying to customize the stiffness of a rocker plate, but there’s something really nice about a few sets of steel springs that you know will deliver consistent performance.
• Quiet: even though it has springs, it doesn’t have the fore-aft noisiness that some plates have. It’s a very quiet setup.
• Sturdy: yes, your bike can move a lot. But you know the unit isn’t going to break or fail in any way, because (as I’ve already mentioned) it’s built like a tank.

Needs Improvement

• I’d still like more side-to-side tilting movement on my front forks. I like the feel of standing up and being able to swing my bars left and right freely, but the steering unit, even at its loosest setting, still inhibited this movement somewhat.
• Too much rear sway: I wasn’t able to test the rear unit with Gymrail’s stiffest springs (red) since they weren’t included in the package, but the mid-stiff (orange) were still a bit to wiggly for me, and the least stiff (black) were definitely not stiff enough. It should be noted that this will be less of an issue for lighter and/or weaker riders. I’m 83kg, with a sprint that tops out at ~1100W. The heavier you are, and the stronger your sprint, the more you’ll notice and probably want to dampen the sway.

Lastly, I must mention that the biggest problem I had with the MX1 was that the rear unit would shift to the right slightly each time I put in a hard, out of the saddle effort. Even after putting down a mat to reduce any possible slipping, it still happened. Then I realized my problem: the floor wasn’t perfectly level!

So this isn’t a flaw in the MX1, but it’s something you’ll want to consider if your floors perfectly level. Because the MX1 uses rollers for fore-aft movement, it will work its way “downhill” if used on a floor that tilts left or right, even slightly. This isn’t a big deal if you aren’t out of the saddle sprinting much, but in a longer race, you may find the rear unit has shifted several inches to one side, which can be a real problem. (This, incidentally, is not an issue “normal” rocker plates have.)

A Word About Innovation

I want to be sure and give kudos to Gymrail, who have put in countless hours to develop a quality product for a very niche market. And they’re not done yet! Their website says they’re working on Zwift-integrated steering with the MX1, as well as braking. Keep up the good work, Harri and team!

Pricing and Availability

The Gymrail Momentum X1 is priced at €1,239.00/$1083, but on sale for €999. So it doesn’t come cheap, and feels especially pricey at a time when good smart trainers can be found for half that price.

Due to its price, I wouldn’t recommend it to every Zwifter. But if you’re looking for a well-built platform offering unprecented levels of motion, the MX1 may be just the ticket.

It is currently shipping to the EU as well as USA, Canada, Australia, and the UK.

Virtual Shifting

With virtual shifting, your chain doesn’t move between different rear cassette cogs when you shift. Instead, when you click to shift using your Zwift Click or Play Controllers, the resistance on your trainer changes so it feels like you’ve changed cogs.

This is how smart bikes like the Wahoo KICKR Bike, Tacx Neo Bike, and Stages SB20 have worked for years (although they use their own shifters, not Zwift’s). Today’s update adds virtual shifting to the KICKR v6 and KICKR MOVE, bringing the list of smart trainers supporting Zwift virtual shifting to four:

1. Zwift Hub
2. KICKR Core
3. KICKR v6
4. KICKR Move

You don’t need the Zwift Cog on your trainer to enjoy virtual shifting. In fact, we would argue that virtual shifting is smoother and quieter with a standard cassette! All you need is a Zwift Click or Play Controllers and your updated KICKR trainer on Zwift.

Keep in mind that you won’t get virtual shifting capabilities if you pair your KICKR via ANT+. It must be paired via Bluetooth directly on your device, via the Companion app, or via your local network.

Race Mode on Bluetooth

Race Mode sends power data to Zwift 10x per second (10Hz), instead of the default of once per second (1Hz). This increased responsiveness can be advantageous in races.

Before today’s firmware update, Race Mode was only available if you connected your KICKR via WiFi or the Direct Connect adapter. Now, as long as you’re connected via Bluetooth, Race Mode will be available.

Updating KICKR Firmware

Installing new firmware is easy using the Wahoo app (available for iOS and Android). Just add your KICKR to your list of sensors if you haven’t already, then click it for details. Tap “Update Firmware” and follow the instructions:

What About Older KICKR Trainers?

Wahoo has said they’ll be releasing virtual shifting for KICKR v4 and v5, but we haven’t seen any hard release dates yet. Stay tuned!

Share the link below and we may feature it in an upcoming post!

The great Mike Hanney, creator of Zwiftalizer, has dropped another helpful video packed full of tips to avoid data dropouts on Zwift. Watch it below, or read our summary below that!

Tip #1: Use Wahoo Direct Connect

Owners of certain Wahoo hardware can eliminate the need for Bluetooth or ANT+ altogether by purchasing the $100 KICKR Direct Connect module from Wahoo. KICKR Direct Connect is compatible with KICKR MOVE, KICKR v5, KICKR V6, KICKR ROLLR, KICKR BIKE SHIFT, and KICKR BIKE V2.

Note: I would expand this tip by suggesting you use your Wahoo device’s built-in WiFi connection if available. KICKR V6, KICKR Move, KICKR BIKE SHIFT, and KICKR BIKE V2 all support WiFi connections.

Tip #2: Use Ethernet

One of the best ways to reduce or eliminate interference from WiFi is to not use WiFi! Hardwire your Zwift device (PC/Mac/AppleTV) into your network.

Tip #3: Use 5.0 GHz WiFi

Using only 5.0 GHz WiFi instead of 2.4 eliminates the interference 2.4 may have with ANT+ signals.

Tip #4: On 2.4 GHz WiFi, Avoid Channel 10

Channel 10 uses the exact same frequency as ANT+ (2.457 GHz) and will thus interfere with those signals. If you must use 2.4 GHz WiFi, use channels 1-5, and do not use the auto channel selection feature on your WiFi router.

Tip #5: Remove Physical Obstacles

Low-power radio signals do not travel through objects well, so remove obstacles between your trainer and Zwift device.

Tip #6: Turn Off Other WiFi Devices

Lots of devices in the home use 2.4 GHz WiFi, which could interfere with ANT+. Turn them off, or force them to use 5.0 GHz.

Tip #7: Use USB 2 Ports

Use the black USB 2 ports on your computer, not the (usually blue) USB 3 ones. USB 3 is an interference generator – Intel wrote this white paper all about it.

Tip #8: Enable High Performance Power Plan

If your power plan in Windows is set to “balanced” or “power saver”, set it to “High Performance” as this will increase the performance of your PC for gaming.

Tip #9: Disable USB Selective Suspend

Windows 10 includes the “USB Selective Suspend” feature which puts USB devices into a very low-power state when not in use. This may cause dropouts when Windows thinks your ANT+ dongle’s USB port isn’t in use when it actually is.

Tip #10: Use USB 2 Extension Cable

Use a simple USB 2 extension cable to move your dongle away from your computer’s WiFi card and into unobstructed proximity to your trainer setup.

Tip #11: Always Plug In Your Laptop

If you run Zwift on your laptop on battery power, you’ll never get good performance since the CPU will be throttled down to save power.

Tip #12: Disable Old ANT+ Protocols

On the Tacx Neo, disable the old ANT+ protocols to “clean up” the signal. See this video from GPLama with more info >

Tip #13: Disable Garmin Connect

Stop the Garmin ANT agent if it’s running in your system tray so it doesn’t try to take over control of your ANT dongle from Zwift.

Tip #14: Don’t Put the Dongle Too Close

If you place the receiver too close to the transmitter, the signal can get distorted and lead to corrupted data.

Tip #15: Update Firmware

Update your trainer/power meter firmware if possible. Newer firmware may improve device pairing, support updated ANT or Bluetooth profiles, or include options for turning off old profiles.

Tip #16: Avoid Sweat

Sweat kills electronics. Put your dongle in a small plastic bag and seal it with a cable tie.

Tip #17: Change Your Batteries

A regular dropout pattern in Zwiftalizer is a sure sign that the battery in your heart rate monitor or power meter is dying.

Tip #18: Line of Sight Positioning

Ensure that your ANT+ and Bluetooth devices have line of sight to your ANT+ or Bluetooth receivers, and those lines of sight don’t overlap with the line between your WiFi router and receiver.

This means you’re getting a direct drive smart trainer with auto calibration, virtual shifting, 10Hz race mode, and +/-2.5% accuracy for an effective price of $350… making this, perhaps, the most smoking smart trainer deal we’ve ever seen.

The Big Question: What About Support?

Some Zwift Hub owners have been concerned about Zwift’s support of the trainer ever since it was announced that the new Wahoo KICKR CORE Zwift One would replace the Zwift Hub One moving forward.

But Zwift has said all along that they will continue to support the Zwift Hub with firmware updates and warranty service. In fact, today, when asked about Zwift’s support of the Hub, they told us, “Absolutely yes, full support is expected for the lifetime of the product. Zwift remains committed to hardware and will continue to invest to bring increasing value and innovation to our customers.”

Plus, as many Zwifters have recently pointed out, the Zwift Hub is already a super-capable trainer. Even if Zwift didn’t issue another firmware update, its capabilities rival smart trainers costing 2-3x as much. We have no reservations in recommending the Zwift Hub… especially at this closeout price.

Virtual Shifting Basics and Benefits

Hub One is built for virtual shifting. What is that exactly, and is it even something you want?

Virtual shifting means your chain isn’t moving between different physical cassette cogs when you shift. Instead, a virtual shift changes the resistance of your smart trainer so it feels like you’ve changed cogs. This is how smart bikes like the Wahoo KICKR Bike, Wattbike, StagesBike, and Tacx NEO Bike have always worked.

There are many benefits to virtual shifting, including:

• Fast, smooth, quiet: with no chains skipping between cogs, your shifts are completely silent, perfectly smooth, and lightning-fast.
• Less wear and tear: your chain won’t wear out as quickly, and neither will the Zwift Cog, since it is built beefy because weight is not a concern.
• Shift under full load: no need to ease off the pedal when shifting under power, as your chain isn’t going to “skip” when virtual shifting like it can with mechanical shifting.
• Compatible across many bikes: no more spinning out on your low-geared mountain bike, or needing to swap cassettes if you swap bikes. The Hub One works with virtually any 8-12 speed bike and auto-calibrates to your physical gearing.
• No more fine-tuning: many riders find they have to fine-tune their physical shifting when they move between outdoor riding and a direct-drive trainer, since the cassettes aren’t lined up exactly the same. The Zwift Cog doesn’t require any such fine-tuning… just shift to a physical gear that has your chain lined up straight on the Cog and you’re ready to ride.
• Expanded shifting: at launch the Hub One supports a virtual 24-speed setup, which is more gears than most riders have on their outdoor setups. Additionally, the gear ratio range is very wide (from .75 to 5.49), meaning everyone should find that virtual shifting offers more easy gears and more hard gears than your mechanical gearing.
• In-game gear visualization: with Zwift’s virtual shifting, you can always see what gear you’re in on screen.
