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 V-Drive uses materials and construction that belie its affordable price. Like all our V-Drive SB0 alloy posts, it's 3D forged and CNC machined—this time from 6061 aluminum. It features the same two-bolt Minimal Top Clamp as our more expensive posts, with zero setback. - 3D-forged and CNC-machined 6061 forged alloy - Minimal Top Clamp (MTC) - MTC head - 5mm chromoly hardware - Zero setback - Fits 7mm standard rails and 7x9mm oval rails - 270 grams

FSA's Afterburner is a tough, lightweight seatpost that works great on road and mountain bikes. Its 1-piece 3D-forged aluminum construction makes it strong and stable while remaining light. And, it's super easy to adjust thanks to the convenient 2-bolt clamp.
