Ritchey Classic 2-Bolt Alloy Seatpost As its name suggests the Classic Seatpost features Ritchey's "Classic" hi-polish silver finish as seen on our favorite vintage bikes. The not-so-classic 3D Forged 2014 construction and 2-bolt design finds a perfect medium between strength, weight and adjustability, while providing vise like hold. The low profile clamp disperses stress on lightweight rails such as those made from carbon, yet the bolts are aligned with the rails for the greatest contact area with the saddle.
