Did a quick test today on a new build I am breaking in. Seatpost worked fine. When I was initially building my new setup a small crack of the cosmetic layer made a small noise, contacted Elita and they said not to worry about it and would replace it if need be. Initial parcel was sent with the wrong internals but was quickly corrected by Elita. Will try to give a full review in a few weeks. Must say it looks amazing. Can't comment on the compliance, its feels as solide as my previous Thompson Elite.
