The FSA SL-K Carbon Seatpost sheds precious grams with its carbon construction, giving you a lightweight, race-worthy post without the wallet-emptying price associated with most carbon posts. Its wall thickness and weave pattern dampen harsh vibration feedback when you're riding over rough roads and uneven trail surfaces. However, don't let its smooth-riding characteristics fool you, it's still plenty stiff when you're pushing hard in the saddle. Moreover, you'll find it's tested to rigorous CEN standards for the utmost in structural integrity and strength.

Unanswered Question

Is this post the Di2 battery compatible version?


I am a big fan

    After buying this originally I actually tried other posts when
    I built up a couple other bikes and end up taking this one on to each bike I ride. It takes my oval rails without any hassle and is easy to adjust. Ride quality is excellent

    Hi. Would this seatpost fit a Fi'zi:k Thar Saddle? Thanks in advance


    FSA SL-K Seat Post

    • Familiarity:I've used it several times

    What can I say? It is from FSA! Great seat post for price, comfomfort and adjustablility! Might weigh a bit more than others but it is not the area to save weight and loose comfort!


    Great value!

    • Familiarity:I've put it through the wringer

    I didn't want to dish out a ton of money on a carbon seat post.. so this was a great buy for me. It's not the lightest carbon seat post out there, but it gets the job done. It's well built (I have over 1000 miles on it) and carbon very noticeably dampens your ride. Also, There's one screw on the seat clamp which adjusts the angle of the seat so adjustment is super easy! Overall: a great buy for a noticeably smoother ride.
