This 26.8mm x 350mm Seat post features a single bolt micro adjustable cradle offering a wide range of adjustability. Produced from lightweight aluminium alloy and finished in polished silver it would make it be an idea upgrade over standard heavier steel posts. Please note: A seat post needs to fit your frame exactly - within 0.2mm. When choosing a new one, please read off the measurement from your old model (stamped in to the base of the post).
