FSA SL-K Carbon Seatpost

 The FSA SL-K seatpost is a full carbon seatpost, in that the whole body of the post is carbon, not a carbon wrap over an alloy or aluminum base. The seatpost head is an aluminum alloy with chromoly hardware. This gives you the stability of the alloy material where you need it most – where the seatpost meets the saddle – but you shave off valuable grams with the carbon post body, not to mention absorbing a lot of road vibration too. The two-bolt head allows for plenty of adjustment, and which stayed remarkably tight on our test rides.
