Elite Justo 2 connected home trainer

The home trainer Elite Justo 2 is the top-of-the-range machine that is redefining the indoor training experience, positioning itself as the new must-have reference on the market. Designed for serious amateurs and professional athletes alike, the Justo 2 combines surgical precision with advanced connectivity features, ensuring that every pedal stroke counts to maximise fitness gains.

Elite precision: the foundation of your performance

High-level training demands reliable data, and the Justo 2 meets this requirement with exceptional power accuracy. This model incorporates an optical torque sensor (OTS) power transducer capable of measuring your effort with a claimed accuracy of +/- 1%. This accuracy rivals the best power sensors on the market.

Justo 2 is a raw power tool, capable of simulating :

• Phenomenal maximum resistance of up to 2300 watts (some specifications indicate 2400 watts).
• Incredibly steep slopes of up to 24%, making it one of the best performing slope simulators in its category.

What's more, manual calibration becomes superfluous thanks to the automatic calibration function. This process ensures optimum, stable performance without regular user intervention.

Immersion and comfort: the transformational advantage

The Justo 2 turns long hours of indoor training into a more natural and comfortable experience, a key factor in staying motivated throughout the season.

Ultra-realistic road feel

The Justo 2 incorporates a 7.2 kg heavier flywheel, ensuring an incredibly fluid, realistic and smooth pedalling feel. This increased weight improves inertia, which is particularly noticeable during sprints and tempo efforts.

Lateral movement for well-being

For the first time at Elite, the Justo 2 incorporates 'Flex Feet', which provide lateral micro-oscillation during pedalling. This gentle movement mimics the natural oscillation of the bike, reducing fatigue on long rides and easing stress on the frame, particularly when the rider goes into a stride. The device comes with two sets of pads: Red (7 degrees of lateral micro-oscillation) and Black (4.5 degrees), allowing the level of flexibility to be adjusted to suit the user's morphology and preferences.

Absolute silence for maximum concentration

The Justo 2 is renowned for its super-quiet operation. It is significantly quieter than other top-of-the-range models, making the noise of the bike's transmission the main audible sound. This is ideal for those who share a living space or live in a flat.

High-speed connectivity and intelligent functions

Connectivity is the key to a smooth experience. The Justo 2 is equipped with all the connection options needed for the future of e-cycling.

• Integrated WiFi and automatic updates the Justo 2 has built-in WiFi connectivity. Connection to the home Wi-Fi network is via the My E-Training application, guaranteeing a fast, stable connection. Firmware updates are installed automatically, guaranteeing constant access to the latest features.
• Fast Track transmission (10Hz): for online competitions, the Fast Track function (or Race) can be activated, enabling power, speed and cadence data to be transmitted at a frequency 10 times faster (10 Hz) than standard (1 Hz). This provides a competitive advantage through ultra-fast response to virtual changes.
• Full connectivity the device is compatible with ANT+ FE-C, Bluetooth (dual channel) and can even be connected to a wired network via the accessory Elite Gateway.
• Bridge function (Bridging): it can be used as a bridge to transmit data from a heart rate sensor, centralising all the data into a single stream, which is essential for limited platforms such as Apple TV.
• ERG Easy Start mode in ERG mode (targeted resistance), the Easy Start function temporarily reduces resistance if the flywheel stops turning. This means you can resume a sustained interval without having to fight massive resistance as soon as you start up again.
• Advanced pedalling analysis: The OTS sensor provides detailed pedalling analysis via the My E-Training application.

Ready to roll straight out of the box

L'Elite Justo 2 is designed for fast installation and maximum compatibility, reducing friction for the user.

• Cassette included unlike its predecessor, the Justo 2 comes with a cassette as standard Shimano 12 speeds (11-34) pre-installed. This allows users to Shimano 12 speeds for immediate use.
• Extended compatibility the Justo 2 fits most modern bicycles, including those with disc or rim brakes. Adapters for quick release axles (130-135 x 5 mm) and thru axles (142 x 12 mm) are included. The cassette body is compatible with a wide range of systems, including Shimano 9/10/11/12 speeds road and MTB, Campagnolo 9/10/11/12 speeds, and SRAM 12 speeds (with XD/XDR body).
• Stand-alone use (Warm-up): a much-appreciated feature is the ability to use the Justo 2 without a mains power supply or software connection. This makes it perfect for outdoor race warm-ups. It can simulate descents or apply a predefined resistance level (1-16) without being plugged in.
• Practical design justo 2: with a weight of 17.1 kg and compact folding legs (folded dimensions: 650 x 300 x 550 mm), Justo 2 is easy to store. A leatherette handle is fitted to the body of the appliance to make it easy to move.

Test the Elite Justo 2

L'Elite Justo 2 has immediately positioned itself as the new landmark in the category of high-end direct-drive home trainers, rivalling established market benchmarks. It's a machine that impresses with its ability to balance cutting-edge specifications with a remarkably fluid and realistic user experience.

Setting up the test

Installing the Justo 2 is simple and straightforward. The home trainer is delivered "almost ready to ride", including a cassette Shimano 12 speeds (11-34) pre-installed, a welcome addition that considerably reduces assembly time for users Shimano 12 speeds. Simply unfold the two side feet until you hear a click and secure the flywheel cover with two screws.

Once the bike is in place (thanks to the included axle adapters, for both quick-release and thru axles), the Justo 2 has a large footprint that gives it great stability, essential during powerful sprints. One small reservation concerns the carrying handle: although the leatherette strap is solid, the total weight of the unit (around 17.1 kg) and its centre of gravity make moving it, even for storage, a little tricky. Nevertheless, its ability to fold up (to just 195 mm wide) makes it easy to store.

Functionality tests

The pedalling sensation is the strong point of this home trainer. The 7.2 kg flywheel (a significant improvement on previous models) offers remarkable inertia and smoothness, comparable to the best competitors on the market. In Simulation mode (on Zwift or MyWhoosh), the home trainer reacts instantly to changes in gradient or gear, even at low speed and low inertia, which contributes greatly to the pleasure of riding.

The Justo 2 is also equipped with Flex Feet, pads under the side feet that offer lateral micro-oscillation. Two sets are included: red (7 degrees) and black (4.5 degrees). This slight movement is beneficial because it simulates the natural sway of the bike, minimising stress on the frame and reducing fatigue on long indoor rides.

In ERG mode, the experience is described as incredibly smooth and precise. The home trainer offers four power smoothing options. The Easy Start feature is a real boon for structured workouts: if pedalling stops in the middle of an interval, the home trainer temporarily removes resistance, avoiding the sudden effort needed to restart the flywheel, a situation often referred to as the 'circle of death'.

Precision and reliability

Justo 2's reliability is ensured by an integrated Optical Torque Sensor (OTS), guaranteeing power measurement accuracy of +/- 1%.

This accuracy was confirmed in rigorous tests, showing 'rock-solid' data that matched the claimed gap during long, controlled efforts. What's more, the Justo 2 incorporates an auto-spindown system that ensures optimum performance without the need for frequent manual calibration, which is very practical for everyday use.

The Justo 2 calculates cadence from power and speed data, but not from a dedicated sensor. Intermittent anomalies (cadence spikes) were observed, but these were largely resolved by a firmware update (firmware 21), ensuring stable performance for training and road racing.

Compatibility and connectivity

Connectivity is one of the areas in which the Justo 2 excels, offering a full range of protocols.

• Built-in Wi-Fi: The presence of Wi-Fi provides a fast, stable connection, which is crucial for virtual races, and ensures automatic firmware updates.
• Fast Track (Race Mode): This function, which can be activated via the My E-Training application, transmits power, speed and cadence data at a frequency of 10 Hz (ten times per second), offering a significant competitive advantage in virtual races on platforms such as Zwift or MyWhoosh.
• Multi-connection: The home trainer supports dual Bluetooth and ANT+ FE-C. It can also be used as a bridge to relay data from another sensor (such as a heart rate belt) to a device like Apple TV, bypassing the latter's connection limitations.
• Stand-alone use: For pre-race warm-ups, the Justo 2 can be used without a mains power supply (in resistance setting mode from 1 to 16).

The Justo 2 is compatible with a wide range of gensets (Shimano/SRAM 9/10/11/12 speeds, Campagnolo, , SRAM XD/XDR) thanks to the freewheel body included and the availability of additional adaptors.

Strengths/weaknesses

The Justo 2 is often regarded as the new global benchmark in terms of features, performance and price.

Questions and answers on Elite Justo 2

How accurate is the power measurement ?

The Justo 2's integrated OTS (Optical Torque Sensor) power sensor has a claimed accuracy of less than 1%, making it one of the most accurate home trainers on the market. Independent tests confirm this accuracy, with results showing a maximum deviation of 1.75% over short intervals and almost perfect agreement over sustained efforts. The home trainer performs periodic automatic calibration without user intervention, guaranteeing consistent accuracy over time

Le Elite Is Justo 2 really quiet ?

The question of noise generates nuanced responses. At moderate power (150W), the Justo 2 is very quiet indeed. However, professional acoustic tests reveal that during intense effort or at high gear ratios, the machine generates low-frequency vibrations that can be felt throughout the house. One tester reported that his family asked him to stop using the trainer after one day because of this low-frequency 'rumble'. The noise level depends very much on the power developed and the gear ratio used

Le Elite Is Justo 2 worth the price compared to the Wahoo Kickr V6 ?

Priced at around €1,099, the Justo 2 is slightly cheaper than the Wahoo Kickr V6 (around 10% difference). It offers comparable specifications: 7.2 kg flywheel compared with 7.25 kg for the Kickr, slope simulable up to 24%, maximum power of 2,300W. The Justo 2 stands out for its integrated Wi-Fi connectivity, its cassette Shimano 12 speeds pre-installed and a free 36-month subscription to My E-Training. On the other hand, the Kickr V6 has a more robust carrying handle and historically more responsive customer support

What are the compatibilities of Elite Justo 2 with cassettes and bikes ?

The Justo 2 comes with a cassette Shimano 12-speed (11-34) pre-installed. It is compatible with road, gravel and mountain bikes fitted with quick-release hubs (130-135 x 5mm) or 142 x 12mm thru axles (adapters included). For cassettes, the home trainer accepts Shimano 9/10/11/12 speeds, Campagnolo 9/10/11/12 speeds, SRAM NX 12-speed and SRAM XD/XDR 11/12 speeds (freewheel bodies available separately). Additional adapters are required for standard Boost 148mm or Super Boost 157mm

Installation and configuration of the Elite How complex is Justo 2 ?

Physical installation is relatively straightforward, according to the testers. The process involves unfolding the side stands, choosing the appropriate adapters, removing the rear wheel and assembling the bike. The trickiest part is replacing the cassette if necessary, which requires specific tools (whip spanner, cassette remover, 17mm spanner or 6mm Allen key). Electronic configuration via the My E-Training app allows the trainer to be connected to home Wi-Fi for automatic firmware updates. The 17 kg weight and leatherette handle make it more difficult to transport than competing models

How does ERG mode work and is it stable ?

The Justo 2's ERG mode features four power smoothing options accessible via the My E-Training app. The 'Easy Start' function makes it easier to resume intervals after short breaks by giving 2-3 seconds to build up the cadence before applying the target power. Some users have reported stability problems in ERG mode following firmware updates linked to virtual gear shifting, with resistors not adjusting correctly. Elite has released firmware version 21 to improve the stability of auto-calibration, but some users are still reporting occasional spikes in cadence

Can we use Elite Justo 2 without a power or internet connection ?

The Justo 2 offers two stand-alone operating modes. When plugged in but not connected to any software, you can pre-set a slope of up to +24% in My E-Training, and the trainer will maintain this resistance even after disconnection. Without a power supply or connection, you can adjust the resistance levels between 1 and 16 preset in the application. This feature means you can train flexibly even when you're on the move or without a network

How bulky and heavy is the Justo 2 ?

The home trainer weighs 17 kg (actual measured weight). Its dimensions are 570 x 720 x 520 mm when open and 570 x 195 x 520 mm when folded. The maximum load capacity is 110 kg. Despite its substantial weight, users point out that the synthetic leather handle on top is not as robust for transporting as competing models. The wide wheelbase and low weight nevertheless ensure excellent stability during high-power sprints
