Na, it’s because the chain pivots do not free in time to release from the teeth. The cause is lubrication of the chain and it’s cleanliness , had it with a new bike… Sometimes the tolerances in the chaine links is out just a minuscule amount. Solution … Take your chain off, clean it in turps, oil it with Wd40 (I know it’s usually pants but you don’t want any stickiness in there) and then keep ridding. As the chain wares and the tolerances even it will stop. Set ups and mechs are all a mythe! Honest.
On an unrelated note, if you want true chain harmony run 2 chains with a powe link and swap them every other ride, do it from new and you will save a fortune a d have that new chain feel all the time, it takes 2 mins!
