Profile Design 1/Zero Alloy Seatpost

Profile Design 1Zero Alloy Seatpost. The Profile Design 1Zero alloy seatpost is an excellent upgrade for your bike, and a great way to shed some grams without sacrificing durability. The 6061 T6 aluminum pillar is strong, stiff, and durable, while the forged alloy topper features a 2 bolt head with micro adjust, making it easy to dial in your perfect saddle position. The uniquely designed upper and lower clamps evenly distribute clamping forces to minimize stress, so they are safe for steel, titanium, and carbon fiber rails.
