Ergon CF3 Pro Carbon Seatpost: Ergon presents a brand new innovative seat post for the road. The post offers a uniquely comfortable ride while remaining lightweight, making it ideal to match to todays ultra-stiff road frames. The seatpost is designed to flex offering added suspension, killing road buzz & soaking up imperfections in the road surface. At the heart are two parallel carbon flat springs. The head has two bearings allowing the saddle to stay parallel to the ground through the travel motion. The function is simple. A bump through the bike pushes the bike upwards, the seatpost flexes in exactly the opposite direction allowing the bump to be neutralised. This is far more efficient than a traditional suspension post. The post keeps that direct road bike feel, but the VCLS flat springs are sensitive to small variations in road surface. A genuine comfort revolution, lightweight & maintenance free. The saddle moves backwards in arc motion, with the carbon suspension beams (Canyon VCLS Technology) equipped with pivots to ensure the saddle remains horizontal. The system is maintenance free, offers simple setback & saddle angle adjustment, & weighs in at about 220 g Seatpost is designed to flex offering added suspension VCLS carbon fibre construction VCLS flat springs are sensitive to small variations in road surface Rotating Flip Head provides greater fore & aft adjustment Compatible with round or oval rails 27.2mm 220g
