Unique comfort, lightweight and aesthetically modern: The Ergon leaf spring seatpost revolutionises comfort on the road bike, all-road and gravel bike. Rough roads and gravel are smoothed out by the two carbon fibre VCLS leaf springs, while the saddle angle remains unchanged by the parallel displacement of the two leaf springs and the floating flip head. The precise and highly sensitive tuned leaf springs work so well that they do not affect the performance of the bike or cyclist. The Allroad Pro Carbon Setback model offers a 25mm setback. Suitable for use in Allroad/Gravel/Cyclocross and Road cycling. It weighs 240 g and comes in a sleek black colour. The clamp is designed for Round Saddle Rails ( 7 mm), and it has a maximum suspension travel of 20 mm. The diameter of the seatpost is 27.2 mm, and the minimum and maximum insertion depth are 110 mm and 210 mm respectively. Made from carbon fibre composite, the weight may vary in production.
