Seatposts

The directional butting of the Energy SBS SB20 seatpost’s 6066-aluminum shaft gives it thicker walls fore and aft for stiffness and thinner walls at the sides to cut weight. A forged and machined alloy head is bonded to the top of the shaft. - 3D forged and CNC machined AL6066 w/ alloy head - Directionally butted for low weight and additional strength - Chromoly hardware - Clamp Style: Standard Rails

The K-Force post’s one-piece carbon fiber shaft and head are topped off with a forged alloy Minimal Top Clamp, giving a full range of adjustment and secure saddle mounting at a very low weight. There’s also the option of mounting a Shimano Di2 battery in the bottom of the post. - One piece continuous carbon fiber construction - Forged alloy Minimal Top Clamp (MTC) - UD carbon finish - Removable mounting hardware for FSA WE or Di2 battery

FSA's Metropolis seatpost is CNC machined from AL6069 aluminum and features a forged alloy single-bolt head with chromoly hardware. Simple and elegant, this seatpost gets the job done weighing a scant 257 grams.

FSA's SL-K Seatpost is lighter and stiffer than ever! Using a UD carbon shaft with a bonded alloy head and a sophisticated MTC clamp design, FSA has achieved what they believe is the finest seat post yet. - UD Carbon shaft, 2-bolt SBS alloy head, and chromoly hardware - Min. Height: 40mm - SB0 = 0mm offset - SB20 = 20mm offset
