my experience is – bloody annoying!
i ditched them for pro2’s in the end, when i first had them i had little knowledge of maintenance in general, but my buddy had to adjust the cones on them every couple of months, the rear one especially….even within the average couple of months there would be some play after a couple of rocky rides…they were so frustrating and frankly felt a lot weaker than pro2’s both on QR…
no issues with pro2’s since one of the best changes i made!
if you can be bothered with maintenance then go for them, if you have a little more money id go with pro2s or equivalent!
of course mixed reviews, but id never go back to them now after having pro2’s
