The Roval Alpinist Seatpost is engineered for lightweight performance, weighing just 136 grams in the 27.2mm x 300mm size. Advanced composite construction delivers both light weight and reliability, making it one of the lightest seatposts available while maintaining Specialized's quality standards. The 2-bolt micro-adjust clamp features a 46mm saddle rail cradle that enables an effective offset ranging from 0mm to 20mm, ensuring precision fit and secure retention. The seatpost is available in two sizes: 27.2mm x 300mm and 27.2mm x 360mm, both with a 12mm setback. It is compatible with both carbon and alloy rail saddles. Backed by a no-fault crash replacement policy and lifetime warranty, the Alpinist Seatpost provides peace of mind. The system has a weight limit of 275 lbs / 125 kg.
