    Full suspension bike on a smart trainer

    Hello!

    Tried to search old topics but found mostly discussion about using full sus mtb on a wheel trainers..

    I'm planning to use Trek Top Fuel 2020 on a smart trainer (Wahoo Kickr) for sweet spot training etc.. Using the suspension lock, and bikes original cassette.

    Do you see any problems with that, or have you heard anyone damaging their bikes when riding full sus mtb on a trainer where the rear is fixed?

    Of course the bikes are facing forces from all directions when riding outside on a trails, so it feels that using it on a stationary trainer wouldn't do any harm...

    Kicker is good as its axle can rotate with the rear triangle when the sus compresses. Not all trainers have this. IDK about how a 12 speed cassette will fit with respect to clearance on the inside as the 50T cog is quite dished. You may not be able to use the 50T cog, which is NBD on the trainer anyway.
    Do the math.

    The bike itself will be fine.
    The cassette will need to be an NX 12 speed to fit, as the freehub is not XD or Microspline. The NX cassette will fit that bill.

    This should fix the freehub problem..?

    If you stick to Erg mode, you can use any cassette, 10/11/12 speed as you just leave it in one gear.
    Do the math.

    I run an Ibis HD4 on a Sarris M3. It's an 11 speed so no issues. I prefer to lock out the fork and shock so it doesn't squish to much. On Zwift I use erg mode for training runs but I like clicking through gears in the free ride routes
