PRO Tharsis Dropper Seatpost 100mm Travel

Aimed at XC and endurance riders, the PRO Tharsis Dropper Seatpost has 100mm of infinite-stop travel; enough to make dropping down a steep descent or blasting through a technical section faster without adding too much weight. All models weigh less than 500 grams thanks to weight-saving features like titanium bolts, with the 27.2mm option coming in at a claimed 405 grams. The 2-bolt seat clamp is secure and easy to adjust whilst the internal cable routing keeps the bike’s lines clean and the cable away from dirt and contamination.
