There’s not a lot new in the V6 KICKR, but the addition of Wi-Fi is nice for those using an Apple TV (like me) because it frees up the Bluetooth connections for other things. Otherwise, I’m not really seeing anything upgrade worthy if you already have a working smart trainer configuration. But, obviously a solid contender if you’re looking for THE BEST smart trainer (or one of the best anyway) available today.
I should probably also mention that there’s also an updated KICKR BIKE, same jazz, but BIKE.
