Overview
Elite took its flagship smart trainer and made it better.
The original Justo was launched as Elite’s top-of-the-range direct-drive trainer, building on the company’s experience with the Direto XR and introducing a number of important developments, including flexible feet, improved power accuracy, automatic calibration, and better ERG-mode control.
Now there is the Justo 2, which was launched in 2024 and still remains one of the best smart trainers on the market today.
At first glance, it might be tempting to think this is simply the original Justo with a new name and a few cosmetic changes. It isn’t. Elite has retained the successful basic architecture of the Justo but made a number of important changes underneath it.
The result is a premium smart trainer designed not only for structured training but also for serious indoor racing.
The main improvements include a larger flywheel, built-in Wi-Fi, a pre-installed 12-speed cassette or Zwift Cog and Click combination, updated electronics, faster data transmission, and improved integration with the wider Elite training ecosystem.
Elite describes the Justo 2 as its flagship smart trainer, and it is easy to see why.
UCI Approved
One of the strongest endorsements for the Justo 2 comes from the UCI, which has verified the trainer for use in the UCI Cycling Esports World Championships. For the 2024 World Championship final, the UCI and MyWhoosh collaborated with Elite to test and standardize the Justo 2, requiring the trainers to meet a 1% power-accuracy standard. This initiative aimed to eliminate hardware differences as a factor in esports racing.
This rigorous process continued for the 2025 World Championships in Abu Dhabi, where all finalists competed on UCI-approved Justo 2 trainers.
For a smart trainer, this represents a significant endorsement. The Justo 2 has been thoroughly tested and verified for the sport’s highest level.
Evolution Rather Than Revolution
The original Justo was already an excellent trainer.
When Elite developed it, they took its previous flagship, the Direto XR, and looked at where improvements could be made. The philosophy was one of marginal gains – improve the accuracy, reduce the noise, make the ride feel more natural, and make the trainer easier to use.
The Justo 2 follows exactly the same philosophy.
Rather than completely redesigning the trainer, Elite has concentrated on the areas that matter most when you are spending hours riding indoors.
The most significant change is the flywheel.
The Justo 2 uses a 7.2 kg flywheel, compared with the 6.2 kg flywheel of the original Justo. The additional mass is designed to provide a smoother and more natural-feeling pedal stroke.
It is a relatively simple change, but one that makes a noticeable difference to the character of the trainer.
Design
Visually, the Justo 2 is nearly identical to the Justo.
The compact, angular design of the original Justo has been retained, including the aluminum-style base, folding legs, and leather carry handle.
It remains a substantial piece of equipment at around 17 kg, but the folding design makes it considerably easier to store than many trainers.
When folded, the Justo 2 measures approximately 57 cm × 19.5 cm × 52 cm.
The compact width is particularly useful if the trainer needs to be stored between sessions.
The Justo 2 comes with two sets of Flex Feet.
The feet allow a degree of lateral movement while riding, helping the trainer mimic the natural movement of a bicycle on the road.
The black feet provide more restrained movement, while the red feet allow greater movement, up to approximately seven degrees.
Like the original Justo, the Justo 2 keeps the plastic cover around the flywheel, which I think detracts from the overall aesthetics.
For those who like a bit of colour, a limited edition in yellow, inspired by the Tour de France, is available.
Setting Up
Elite has made the Justo 2 relatively straightforward to get connected. You can now purchase it with the Zwift Cog and Click. This means that you simply unbox the trainer and connect your bike to it.
There is an alternative option, where you can purchase it with a 12-speed road cassette already installed.
That means a compatible 12-speed road bike can be mounted and ridden without first having to purchase and install a cassette.
For riders using another drivetrain, Elite provides alternative freehub and cassette options.
The trainer supports a wide range of road, gravel, mountain, and city bikes, with adapters available for different axle standards. It is also Zwift Ride compatible and works seamlessly with Elite’s new Square.
Once the bike is installed, the next step is to connect the Justo 2 to Elite’s My E-Training application.
This is worth doing even if your intention is to ride on Zwift.
The app allows the trainer to be configured, connected to Wi-Fi, and updated with the latest firmware.
Once that is completed, it can then be connected to your preferred training platform.

Features
Built-in Wi-Fi – Perhaps the biggest practical change compared with the original Justo is connectivity.
The Justo 2 has Wi-Fi built into the trainer.
This is important because wireless connectivity has traditionally been one of the weak points of indoor cycling.
Bluetooth works extremely well, but when you are racing on Zwift, MyWhoosh, or another platform, the last thing you want is a connection problem interrupting the race.
With Wi-Fi, the trainer can communicate directly with the home network, providing a more stable connection.
Elite has also designed the Wi-Fi functionality to allow firmware updates to be downloaded automatically.
Once configured, the trainer can check for updates and install new firmware, helping to keep the hardware current as Elite develops new features.
There is also an Ethernet option using Elite’s Gateway accessory for those who want a wired connection.
Fast Track 10 Hz Data – For anyone interested in esports racing, one of the most interesting features is Fast Track.
Normally, smart trainers transmit data at around 1 Hz.
Fast Track increases this to 10 Hz.
That means power, speed, and cadence information can be transmitted much more frequently.
For normal endurance training, this might not make a huge difference.
For racing, however, it becomes much more interesting.
When you attack, sprint, or accelerate, every pedal stroke matters. Faster transmission means the software can receive changes in your effort more quickly.
Elite specifically positions the function for online and virtual competition.
For a trainer being used for serious Zwift or MyWhoosh racing, this is a significant upgrade.
Ride Experience
The larger flywheel is arguably the most important hardware change.
At 7.2 kg, it provides a smoother and more progressive feeling under acceleration.
The result is a trainer that feels less like simply pedalling against resistance and more like riding a bicycle outdoors.
As the gradient changes, the resistance builds progressively rather than simply switching between resistance levels.
The Flex Feet allow a small amount of lateral movement, ensuring a comfortable ride.
That movement is designed to replicate what happens when riding outside, particularly when producing higher power.
Accuracy and Responsiveness
Power accuracy is one of the areas where the Justo 2 really matters.
Elite claims accuracy of less than 1%, thanks to its integrated Optical Torque Sensor.
That means the trainer can effectively become the power meter for your indoor training setup.
Independent testing has backed up Elite’s claims, with the Justo 2 producing power figures very close to dedicated power pedals during both steady efforts and racing.
For structured training, that consistency is important.
If your workout calls for 300 watts, you want 300 watts to mean the same thing from one session to the next.
For esports racing, responsiveness is equally important.
The Justo 2 reacts quickly to changes in power demand, while Fast Track can increase the frequency at which data is transmitted to the training software.
This combination makes the Justo 2 particularly well suited to competitive indoor cycling.
ERG Mode
ERG mode is an area where Elite has put considerable development effort.
The trainer automatically controls resistance to ensure you hit the target power specified by the workout.
One of the problems with ERG mode on some trainers occurs when an interval starts at a high-power level.
If you are not already moving quickly enough, the resistance can become extremely difficult to overcome.
Elite’s Easy Start function helps address this.
Rather than immediately applying the full resistance, the trainer gives the rider time to build enough momentum before increasing the resistance.
This makes starting a hard interval considerably more manageable.
The Justo 2 also offers power-smoothing options, allowing the rider to choose how power data is displayed during ERG workouts.
The result is a very controlled ERG experience.
Stand-alone Operation
Another useful feature is the ability to use the Justo 2 without being permanently connected to a training application.
The trainer can operate in stand-alone modes.
If it has power but isn’t connected to training software, a gradient can be preset using the My E-Training application and subsequently maintained.
There is also a resistance mode that can be configured before training.
This means the Justo 2 isn’t completely dependent on Zwift, MyWhoosh, or another platform to be useful.
Noise
Noise was already one of the strengths of the original Justo. The Justo 2 is equally quiet.
The combination of the flywheel, belt, and redesigned internal components produces a trainer that is surprisingly quiet. Having tested a lot of smart trainers, I would say that it is easily one of the quietest, and it’s interesting to see the evolution on this front because compared to older generations of indoor trainers, the Justo 2 is remarkably unobtrusive, with the loudest item in my indoor set-up being my fan.
RIZER Compatibility
The Justo 2 is fully compatible with Elite’s RIZER.
The RIZER changes the angle of the front of the bike while the Justo 2 controls the resistance at the rear.
Together, they create a much more immersive indoor climbing experience.
For riders who want to replicate the physical sensation of climbing rather than simply seeing a gradient number on a screen, this is one of the most compelling combinations available from Elite.
Interestingly, the same design feature on the RIZER is carried through to the Justo 2, that being the leather carrying strap.
Zwift and Virtual Cycling
The Justo 2 is designed to work with all the major indoor cycling platforms.
That includes Zwift, MyWhoosh, ROUVY, TrainingPeaks Virtual, and Elite’s own My E-Training platform.
As mentioned, you can now purchase it with the Zwift Cog and Click, allowing virtual shifting on Zwift without requiring a conventional cassette drivetrain setup.
For anyone using the trainer primarily for esports, the combination of Wi-Fi, Fast Track, accurate power measurement, and responsive resistance control makes the Justo 2 a solid purchase.
It is not simply a trainer for completing winter workouts; it is a trainer designed to compete, with a maximum wattage topping out at 2,300. I’ll be pleased just to hold 300 watts and possibly double that in a sprint, so the limiting factor is certainly rider capability over equipment.
Cost and Warranty
The Justo 2 sits at the top end of the price for smart trainers, but you are paying for a premium smart trainer that comes with a 4-year warranty, a program that Elite has just launched.
In the UK, the Elite Justo 2 is currently around £1,099.99. In Europe, Elite’s recommended retail price is €1,099, whilst in the USA, it is $1,550–$1,850, depending on the retailer/version.
Elite has introduced a new warranty extension program for the Justo 2 (all three versions: Cassette, Zwift Cog and Click, and Yellow Ltd Edition).
Users will be able to extend their warranty coverage up to a maximum of 4 years by registering their trainer on a dedicated Elite portal: redeem.elite-it.com.
Registration must be completed within 3 months of purchase.
The extension will depend on national warranty regulations:
- In countries with a 2-year legal warranty, users will be able to add up to 2 extra years.
- In countries with a 3-year legal warranty, users will be able to add 1 extra year.
In all cases, the maximum total coverage will be 4 years.
So yes, you are paying for a premium product, but it comes with a 4-year warranty. If anything goes wrong, you know you will be covered, which is nice to know and makes the overall package more attractive than simply looking at the trainer’s purchase price.
Summing Up
The original Justo was already an excellent smart trainer.
The Justo 2 doesn’t attempt to reinvent it.
Instead, Elite has looked at what mattered and improved it.
The larger 7.2 kg flywheel improves the riding experience. The Flex Feet provide more natural movement. The integrated power meter delivers sub-1% claimed accuracy. Wi-Fi provides a much more modern connection method, while Fast Track gives competitive riders faster data transmission.
The pre-installed cassette also makes getting started considerably easier.
What is particularly impressive is that Elite has managed to add this technology without turning the Justo 2 into a huge piece of equipment.
It remains compact, foldable, and relatively easy to store.
For the serious indoor cyclist, however, the most important question is simple: How does it ride?
The answer is very well.
The Justo 2 delivers a smooth, realistic, and responsive experience, while the combination of accurate power measurement and sophisticated resistance control makes it equally comfortable handling a structured ERG workout or the intensity of an online race.
It is also remarkably quiet.
For me, that combination is what makes the Justo 2 stand out.
It isn’t simply about adding more technology for the sake of it. The improvements are focused on making the indoor riding experience better.
The original Justo was Elite’s flagship.
The Justo 2 takes that platform and brings it firmly into the next generation of indoor cycling.
For riders who want a premium trainer capable of serious training, racing, and long-term use, the Justo 2 deserves to be very high on the list.
