Tacx Flow Smart thumping noise

My Tacx Flow smart trainer has started developing a thumping noise which seems to be once per revolution.  The noise seems to be somewhere around the roller.  Anyone else had this and know how to get rid of it.

  • Sorted this out.  For anyone that starts experiencing the same issue, check your tyre!  Just checked mine and it was flat.  Everytime it went round and the valve passed over the roller it banged because there was no air in it.  Pumped up and it's all quiet again!
