This one's a little awkward to write, because the spec sheet isn't close — and the cheaper trainer is the one winning it. Let's get into why that's more complicated than it sounds.
Spec-by-Spec

| Connectivity | ANT+, Bluetooth x3, WiFi, Ethernet | ANT+ FE-C, Bluetooth x2, WiFi, Ethernet |
| Extra features | Race Mode, EasyRamp | Side-to-side movement, pedal-stroke analysis, runs without mains power |
| Cassette included | Yes | Yes (12-speed) |
Yes, the Justo 2 Has the Better Spec Sheet
Higher power ceiling, higher gradient simulation, matching accuracy, and it throws in side-to-side movement and per-pedal-stroke analytics — features the V6 simply doesn't have — for roughly €300-500 less. On paper, this isn't a close contest.
So Why Would Anyone Buy the V6?
A few real reasons, not just brand loyalty:
Ecosystem maturity. Wahoo's app, firmware update cadence, and third-party integration support are more battle-tested. If you want the safest, most predictable long-term ownership experience, that history counts for something.
Race Mode and EasyRamp. These are small but genuinely useful features for anyone racing seriously on Zwift — Race Mode boosts the data broadcast rate for sprint finishes, and EasyRamp smooths the resistance ramp-up after you stop mid-interval, which sounds minor until you've mid-workout wrestled with a trainer that snaps straight back to full resistance.
You already own Wahoo gear. If your bike computer, other sensors, or training app already live in the Wahoo ecosystem, staying in one ecosystem has real convenience value that doesn't show up on a spec sheet.
Where the Justo 2's Extras Actually Matter
The side-to-side movement and pedal-stroke analysis aren't gimmicks — riders who care about pedaling technique or who find rigid trainers uncomfortable on long sessions will notice both. Running without mains power is also a genuinely unusual and useful feature if your setup isn't near an outlet.
The Verdict
If you're optimizing purely on specs and price, the Justo 2 is the stronger buy, full stop. The V6 earns its higher price through ecosystem maturity and a couple of racing-specific conveniences — worth it if those specifically matter to you, harder to justify if you're comparing on paper alone.
