The Prologo Dimension Nack CPC 143mm Road Saddle has all the features of the original Nack, but now with our patented CPC (Connect Power Control) technology, introduced on Dimension, we can satisfy every high-end customer helping him to reach his best in comfort, performance and feeling with the bike. The CPC is manufactured with a special 3D nano-polymer positioned in strategic areas of the saddle and it provides grip and an optimal position in all weather conditions, ensuring the maximum shocks absorbing and anti-vibrations: in the latest version called CPC AIRING, it increases air flows wicking away both heat and sweat.
