What Our Gearhead(R) Experts Are Saying:"I have been running the PRO Koryak Dropper Post through a full season of trail and enduro riding and it has been completely reliable from the first ride to the last. The 2:1 lever ratio makes actuation effortless even mid-descent when your hands are working hard, and the infinite travel means I can set my saddle height exactly where I want it for any feature rather than hunting for a fixed position."A dropper post changes the way you ride a mountain bike, and 170mm of infinite travel changes it significantly. The PRO Koryak Dropper Post was built for trail and enduro riders who want a robust and reliable post that disappears into the ride and reappears exactly when you need it, dropping smoothly to whatever height the trail demands and returning crisply when the descent is done. The alloy construction is built to handle the repeated loads of aggressive trail riding, and redeveloped seals extend the lifespan of the post through seasons of hard use in wet and muddy conditions. Internal cable routing keeps the cockpit clean, the 2-bolt head design secures your saddle with confidence, and the 2:1 lever ratio makes actuation light and effortless even when your hands are fully occupied managing the trail ahead. Three diameter options at 30. 9mm, 31. 6mm, and 34. 9mm ensure a proper fit across a wide range of frame specifications.
