ks i900 – question?

So, had mine a week or so now, just fitted it to my bike. I was under the impression that the system used was meant to eliminate any play in the post. When sitting on, or even just holding the saddle there is a few mm of rotational play. Now its not a problem as such, just curious if any other owners could let me know if this is normal or not. Maybe my expectations were a tad high 😉

No rotational issues with mine and Ive had it a few months.

No play issues with mine either, had it for four weeks and about 12 rides
Send it back mate

I’ve had mine for about a month and 6 or 7 rides. I have also noticed a few mm rotational play, but I’m not sure if it was like that from new. I don’t notice it when riding.
