No stiff link, and it's definitely skipping over the top.
But it's pretty much any gear, slightly less worse on the big ring than the little.
It was good in a way in that it stopped me hammering anything at Ride 100, but my god it's annoying.
Sometimes it's like it's just slipped one tooth, a big "Chung!" And carries on. Sometimes it slips/catches/slips/catches and so forth until I switch to a gear I'm putting a low enough torque on.
Forget standing on the pedal to start from a standstill.
As I said before the shifting is perfect in the workstand and very quiet on the whole otherwise...
