I just got my Fizik Arione R1 and now need a seatpost to go with it (the stock SLK I have doesn't fit the oval rails, and I want to replace it anyways).
I've ready many different accounts of attempts to match seatposts/clamps with carbon braided rails and am left more confused then when I started. Right now I'm looking at the 3T ionic 0 ltd stealth, but am unsure what I need to do get the fit right. As I understand it 3T sells this Difflock Mechanism to make this match work: http://store.3tcycling.com/en/spare-parts/seatposts/difflock-mechanism-with-oval-rails-169.html
It's unclear to me if when you order a 3T seatpost they provide a clamp at all, and whether you need to replace that clamp with the difflock mechanism or you they don't provide you one at all. This mechanism is sold out and I don't see it sold anywhere else so that's awesome..
Anyone bought the Ionic for braided rails? Was it necessary to go ahead and buy the Difflock Mechanism to make the seatpost compatible?
If not, I'd love to hear from the other owners of fizik carbon braided saddles about their seatpost set up. I'd prefer to go 3T since I own a Cervelo and they compliement each other quite well.
