Lighter and stiffer than ever.

Tipping the scales at only 222 grams for the 27.2 x 350-millimeter version, the FSA SL-K Carbon SB0 Seatpost shaves precious weight from your carbon road bike or cross-country race bike while providing an ideal balance of stiffness and smooth ride quality with its unidirectional carbon construction.

At the top of the post, the SL-K Carbon SB0 uses a Minimal Top Clamp (MTC) that further reduces weight, yet still allows for fore/aft adjustment of seat position with its two-bolt design. Chromoly hardware keeps weight down even more and is highly resistant to the elements. It's available with a polymer Di2 battery holder for those using the latest electronic drivetrain from Shimano.

Clamp doesn't fit correctly

  • Familiarity: I've put it through the wringer

This is swell seat post. I've had it for about six months. I noticed a creak, and when I checked out the fit, I found that the front seat clamp wasn't parallel with the saddle rails. No amount of fussing with the fixing bolt would make it lay correctly. I contacted FSA; they responded a couple of times, but weren't able to provide support.
