Details

The KFX post has a one-piece carbon shaft and head topped with a forged alloy Minimal Top Clamp and M5 chromoly hardware, giving secure saddle mounting at a low weight.

Fit and compatibility

It fits frames that take a 31.6mm seatpost. Check your current post's diameter, which is usually printed near the insertion mark, before ordering. The 25mm setback puts the saddle behind the post centre, which suits a traditional position. It's carbon, so use carbon assembly paste and don't over-tighten the frame's seat clamp.

Fitting

Keep at least the minimum insertion marked on the post inside the frame, and torque the saddle clamp to the figure marked on the head. Our workshop can fit it and set your saddle height for you.

If you're unsure about width, length or clamp size, tell us what's on the bike now and we'll help you pick the right one.

FSA warrants its products against defects in materials and workmanship for two years from the original purchase, for the original purchaser. Carbon seatposts that are cracked or damaged where the frame's seat clamp tightens aren't covered.

For a warranty claim, return the item to Tune Cycles with your proof of purchase and we'll manage the claim for you. FSA products come with guarantees that can't be excluded under the Australian Consumer Law, and this cover is in addition to those rights.
