This is starting to bug me now. My Argon 18 E117 TT bike is silent at lower cadences on the trainer but at cadences of 105rpm + its always made a rhythmic clack, clack, clack. Its started do it at circa 90rpm+ though. Any ideas?
I replaced the left cleat at the start of the season perhaps I should replace the right cleat and see how I get on 
Edit - Cleat replaced: I’ll see if that was the issue tonight. The rubber bits seem good and you can still easily read xpedo but the hard plastic looks worn in places.
