Updown Internal

aluminium. MTB.

A dropper-post revolution.

The Funn UpDown dropper post is your solution to poor dropper performance.

The UpDown is an internally routed dropper post with a cable-operated design. It is available in 125mm and 150mm drop options and comes with our much-loved, fully CNC’d lever.

The lever, a work of art in its own right, has been praised by riders and the media. It has a large, comfortable thumb-paddle and a smooth, easy-to-use action. It can be mounted left or right, top or bottom and works with posts that tension either from the lever or from the post.

The UpDown dropper uses a first-of-its-kind RCR Cartridge which allows users to reset the post’s hydraulic circuit and keep the unit working good as new for longer. Post maintenance is quick, easy and inexpensive and spares are available direct from Funn when you need them.

The UpDown guarantees more time riding and less time fixing.
