Getting its namesake from the ancient Greek architectural column, The 3T Dortico Pro Seatpost is as every bit as durable as the name implies. This handsome alloy seatpost will keep you comfortably balanced on your bike for years to come -- without costing you a race seasons worth of entry fees. 3T keeps it simple with the Dorico Pro Seatpost. The shaft is made from light weight 7075 aluminum, and topped with a matching alloy seat clamp. Sturdy stainless steel hardware secures your saddle to the clamp without the worry of them rusting in place. The recessed bolts that hold the twin clamp yokes give you precise, no-slip adjustment with your saddle angle for long-term comfort while you ride. The 25mm setback stretches out your cockpit just a little bit, providing you with a more efficient pedal stroke.The 3T Dorico Pro Seatpost is anodized Black and comes in two diameters 27.2mm and 31.6mm. It is available in two lengths 280mm and 350mm.
