Tacx Flow Smart started making noise when spinning up.

See video below for example of the noise. Sounds like something is caught in the fan but nothing obvious.


  • Same here. See vid. Sounds like something stuck in fan but cant find it :/

    could this be the bearings? 

    someone on youtube suggested screwing on the little metal part that the wheels connects to

    see here (last faq / image with the holes - it says to put powerful glue there) - anyone did that? support.garmin.com/.../

    I opened the casing, could not find what is causing this...  my neighbor is very unhappy with this noise

    Also note the strategic cooling fan bolted on with duct tape ;) the poor thing overheats on long climbs in zwift with high watt / low rpm

    any hints would be appreciated, I really cant afford a neo2t 

  • I have the same issue. Put thousands of miles on the turbo over lockdown and it’s now measuring around 85db. I’m anticipating complaints from neighbours 

  • Check the resistance unit casing which is in two parts with tabs holding them together, the halves can become misaligned if knocked or handled and only a slight misalignment will cause a loud noise then the unit turns

  • I raised a case with support - they are offering me a resistance unit (motor) replacement at ~80% of the new price (the trainer is outside warranty at 3,5 years). Not happy, but still better than any of the alternatives

    lets see how this plays out

  • Thanks. The casing appears to be aligned but can notice that what I’m presuming is a metal flywheel that holds the magnets (?) is slightly out of true. 
    looked into the epoxy fix as the metal runner clicks a bit if pressed. Epoxy will arrive today and I’ll give it a go. 
    For what it is, the turbo does it’s job. I was going to buy a flux s last year but was pretty impatient and picked this up. Would much rather spend money on a new set of wheels Joy
