Did you get the proper inserts, I am asking as I got the wrong ones on the first delivery and the post was sliding no matter what.. They kindly sent another one and apologized.. all good now and thanks for the kinds words.. tear occurred playing tennis,, will stick to road bike for now

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.

Ideally, the cassette should match the chain. Where this is not particularly helpful is that none of the XDR cassette manufacturers actually specify which chain their cassettes are designed to work with.

From what I have seen and read, XDR plays nice with sram obviously and YBN.. not kmc or connex
