This is the seatpost that 2016 National Hill Climb champion Lou Bates used. See this article for more: https://www.google.co.uk/amp/amp.timeinc.net/cyclingweekly/news/racing/how-a-bike-made-from-parts-bought-on-ebay-won-the-national-hill-climb-championships-300674%3Fsource%3Ddam

Super light at 140g with the option to cut it down further if you don't need the whole 400mm length. Well constructed from carbon fibre with titanium bolts and saddle clamp.

Only bought 3 months ago but after a bike fit it transpires I need a seatpost with 25mm of setback.

This will fit a Cannondale Synapse or other frame requiring a 25.4mm post and it gives a lovely comfortable compliant ride, absorbing lots of road buzz. There are also loads of different shims you can buy cheaply so this post will fit frames designed for larger posts e.g. 27.2mm or more.

Paid £54 new 3 months ago and waited three weeks for delivery so grab a bargain and get it quick!
