Usually, noise and/or other little shifter groupset anomalies are due to little misalignments between the system and the home trainer.
Such anomalies are usually not connected to any sort of issue or defect of the home trainer itself.
We can confirm that Elite's freewheel hub (11-speed cassette - in those home trainers where it comes pre-assembled such as the Suito) is perfectly compatible with the original bicycle groupset.
However, bicycle's frame and groupset permissible tolerances require sometimes small (micro) adjustments of the rear derailleur or the spacers inside the cassette in order to perfect their efficiency.
In this case, we advise contacting a professional mechanic to streamline the functions of the bicycle + home trainer system.
