Old problem, new solution.

Recognizing a frustration many riders and mechanics have with making saddle adjustments, FSA steps up with the new FSA SL-K Carbon ITC SB0/15 Seatpost. What does all that mean? Let us explain. The SL-K family of components from FSA is premium gear that somewhat undercuts the prices of the company's top-line F-Force components. As such, the SL-K post is made of unidirectional carbon fiber, keeping weight down and making the post able to absorb a bit of shock from your ride. At the top of the post, however, is where the real brains come in. FSA's new ITC (Independent Top Clamp) design not only makes popping the saddle on and off the post very easy, it also allows for independent adjustment of the saddle's angle and position. Further, the clamps' side plates can be easily repositioned to toggle between two different offsets: 0mm or 15mm. The FSA SL-K Carbon ITC SB0/15 Seatpost comes with two different logo finishes — either Red or Black — and in 31.6mm or 27.2mm diameters. All versions are 400mm in length, and the post is appropriate for either road or mountain biking.

  • UD carbon shaft
  • Alloy head

Will this work with oval rails?

Great post!

    This post is beautiful. The 0mm or 15mm setback is a nice option to have. Though once you set it, it is unlikely you will ever have to change it. This is a nice option to have when your dialing in your saddle height and set back.
    The clamping mechanism for the saddle is real nice compared to standard clamp. FSA really did their homework on this design.
    I was pleasantly surprised the FSA included paste as well!

    works great//does exactly what it should

    • Familiarity: I've used it several times

    I bought this because I liked the idea of 0mm or 15mm setback options.. and it does just that, so I can dial in my fit beautifully!! It's also one of the easiest to get the saddle in and out without having to do that ballet dance between dropping all the parts and screws and trying to jam the rails in there. Easy peezie. No creaks or squeaks so far, but it's pretty new.. Funny thing though, the scant directions sheet has no mention of turning the plates around the other way to change the offset! If you didn't know, you'd never figure that out.

    All in all, very pleased with the easy setup and especially at the sale price.!

    Thanks CC for your great products and descriptions !!!

    Any idea when these are due to come back in stock? I have one on backorder and selfishly want to finish my bike build.



    Hey Patrick,

    Thank you for checking on this backorder. According to the date FSA has provided us this seatpost should've arrived by now. We are expecting the post to arrive any day now.
