Elite Justo 2 Review: Wi-Fi, Sub-1% Accuracy and a Quiet Ride

Elite has been making indoor trainers in Italy since long before anyone rode a virtual watopian volcano, and the Justo 2 is the company's answer to the question of what a flagship trainer should do in 2026. The answer, mostly, is stop irritating you. Built-in Wi-Fi means the trainer connects to Zwift by itself rather than through whichever Bluetooth device happens to be feeling cooperative. A cassette arrives fitted. The claimed accuracy is better than 1 percent, which is the level where you stop wondering whether your FTP test was real.

At roughly £979 on Amazon UK it is not a casual purchase, and there are trainers at half the price that will get you fit. What the Justo 2 buys is reliability of both connection and numbers, and if you train to power rather than feel, those two things are the whole product.

Who it is for

Buy this if your winter training is structured: intervals to a plan, a race on Zwift most weeks, an FTP number you actually act on. The accuracy and the Wi-Fi both pay off in that context, and the 7kg flywheel plus 24 percent gradient ceiling mean the trainer never becomes the limiting factor.

If you ride indoors twice a month to keep your legs turning over, this is far more trainer than you need. A wheel-on unit or a cheaper direct drive model will do that job, and our best turbo trainer UK guide covers the sensible steps down.

Accuracy and road feel

The Justo family is built around an optical torque sensor rather than a strain gauge inferred from motor current, and Elite claims better than 1 percent accuracy across the range. In practice that means the number on your screen matches the number a decent crank-based power meter reports, which is the whole point of a premium trainer. Anything worse than 2 percent and your zones drift enough to matter over a training block.

Ride feel comes from the 7kg flywheel and the way the trainer applies resistance when the gradient changes. Coming off a virtual climb onto a descent, the Justo 2 releases resistance smoothly instead of the sudden slackening cheaper units give you, and grinding up a 15 percent ramp at 60rpm it stays even rather than pulsing. This is the difference you feel within one ride and then stop noticing, which is exactly as it should be.

Wi-Fi is the real upgrade

Every experienced indoor cyclist has a Bluetooth story: the trainer dropping out forty seconds into a fifth interval, the laptop pairing to the heart rate strap but not the trainer, the phone that decides to hand off to a smart speaker mid-race. Elite's fix is to skip the personal-area radio entirely for the main connection and put the trainer on your home network, where it talks to Zwift directly.

It works, and once you have used it the old way feels primitive. Two practical notes. The Ethernet port matters more than it looks if your trainer lives in a garage or shed where Wi-Fi is thin, and firmware updates arrive without you hunting for the phone app, which is a small mercy given how often trainer firmware used to be the cause of the problem it was meant to fix.

Training with it

Indoor cycling gets an unfair reputation as junk miles, largely because unstructured indoor riding is genuinely dull and easy to fudge. Done properly it is potent: a 12-week programme of three indoor cycling sessions a week improved body composition, aerobic capacity and lipid profiles in a 2020 study of women with obesity, and the same principle applies to a rider chasing an FTP number. The trainer removes every excuse the weather can supply, which is most of them in a British February.

For general health the bar is lower than most cyclists assume. The NHS asks for 150 minutes of moderate activity a week, which three trainer sessions clear comfortably. What the Justo 2 adds is the ability to know precisely what you did, so progression stops being guesswork.

Pair it with a chest strap rather than relying on wrist optical heart rate, which struggles during hard intervals; our best heart rate monitor UK guide covers the options worth buying.

How it compares

Against Elite's own range, the Avanti is the value pick and the Direto XR-T the older workhorse; the Justo 2 adds Wi-Fi, better accuracy and a fitted cassette over both. Against Wahoo, the KICKR CORE 2 undercuts it substantially and gets you most of the way there, while the full KICKR range trades on ecosystem rather than raw numbers.

The honest summary is that the top three or four direct drive trainers are now close enough that accessories, price on the day and which app you use should decide it. If none of this feels worth £979, the exercise bikes section covers smart bikes and spin bikes that need no bicycle at all.
