Hi everybody.
I’m having some issues with a 2-month old Neo 2T (I decided to switch to Tacx after 3 faulty Wahoo KICKRs)
Whenever I do a workout in ERG mode in the 36 in front, I feel very strong vibrations through the pedal cranks, no matter which cog in the back and no matter the cadence.
Some other clues:
- The issue becomes less noticeable when moving to the 52 in front, probably because the flywheel spins faster. However, this significantly increases the vibration from the turbo which resonates badly in the wooden floor of our flat.
- Both my girlfriend and I have a Cannondale SuperSix Evo with ultegra and disk brakes. The issue is much more noticeable and annoying on my bike, but we can also feel it on my girlfriend’s bike.
- Indexing should be ok.
- I cleaned and lubed the chain last weekend, but unfortunately nothing changed.
From the research I gathered, the issue could be explained by some of the following
- Free-hub bearings
- Old chain/new cassette: I did a bike service mid-January and I got a new Shimano HG-X11 chain. I bought a new ultegra 11-32 cassette for the trainer and since then I rode ~2000km on it. I checked the chain wear with a wear meter and it doesn’t look too bad.
- Bearings in bottom bracket: even if this should have happened between January and now.
- Bent rear derailleur: when I tighten the skewer, the frame compresses and the derailleur moves quite a bit. I’m wondering if it’s also changing its angle…

Something wrong with the turbo itself: I saw quite a few people complaining about this same issue on the Tacx Owners facebook group, so it might well be a firmware issue. This wouldn’t be too weird also considering that my Neo 2T reports 30/40W less than my previous Wahoo Kickrs (I don’t have a power meter to do a proper comparison, but my FTP dropped from 296W in December on the Kickr to 262W in February on the Neo2T after having done 8 weeks of Trainerroad half-distance triathlon base program… and FTP doesn’t go down when training consistently on Trainerroad
)
Has anyone had this same issue and found a solution?
Thanks in advance for your help!
