  • Brand-X Ascend II Dropper Seatpost (105,125,150)

    Available in 105mm, 125m and 150mm travel options, the Ascend II mountain bike dropper enables you to quickly and reliably adjust your saddle height without interrupting your pedalling flow. Offering smooth and consistent operation, this budget-friendly component will put you in the perfect riding position for tackling every section of the trail.

    Externally Routed Dropper Seatpost

    Building on the success of the Ascend Dropper Seatpost, this aluminium dropper post is available for those who have a rig without internal cable routing: Brand-X is bringing affordable and reliable dropper posts to the people! With infinitely smooth adjustments and an ergonomic lever that can sit on the left or right of your cockpit, the Brand-X Ascend II Dropper Seatpost is the upgrade that your bike needs. To avoid cable movement/pull, this dropper seatpost's cable is actuated from the mid-cap and delivers consistent performance.

    Please Note: The 31.6mm and 30.9mm diameter options come with the 1x Shifter Lever and the 27.2mm option comes with the 2/3x Paddle Lever. The 27.2mm size also has a 2-piece saddle clamp so the saddle will sit slightly higher than on the 31.6mm and 30.9mm options.
