The Brand-X Ascend CX dropper post is a 27.2mm internally routed dropper seatpost designed for use on road, cyclocross or gravel bikes. It is also perfect for use on mountain bikes which use a 27.2mm seatpost diameter. 

Having seen how dropper posts increase confidence, control and rider enjoyment on mountain bikes, Brand-X created the Ascend CX post to bring the same benefits to drop-bar bike riders. With click of a button you can drop your saddle out of the way to increase descending confidence for off-road riding.

Operated easily via a paddle style remote on either side of your cockpit, the aluminium CX Dropper Seatpost is easily installed on bikes with internal cable routing. The ascend CX comes with a drop bar specific lever designed to fit 31.8mm drop handlebars. For use with standard flat handlebars, the standard Brand-X lever is required as an additional extra.

The post is cable actuated at the bottom of the dropper post via a linkage mechanism which eliminates cable pull/movement for a smooth and reliable performance. Like all Brand-X's seatposts the Ascend CX offers the best value and reliability on the market.
