With the introduction of Eclat's new Exile trail and transition focused line of products, they wanted to offer their own take on the classic and now super popular again railed seat setup. For the Exile Seat Post they simplified the railed system as much as possilbe, by using a super strong forged 6061-T6 alloy post and a very tidy one-bolt clamp Eclat were able to offer a seat post which is as easy to assemble and as strong as a conventional pivotal system. ###section### Product Specs TYPE: Railed LENGTH: 135mm DIAMETER: 25.4mm WEIGHT: 0.44lbs (200g) Colour: Silver, Black; Size: 200mm
