Using your e*thirteen Vario Infinite Dropper Seatpost is easy. First, if you need to adjust the travel, use the unique upper bushing to change it in 5mm increments up to 30mm. You can do this without any tools and without removing the post from the bike. When riding, use the cable - actuated Vario 1x Dropper Lever (recommended) to adjust the seat height as you need. You have 12mm of fore/aft saddle adjustment and 28° of total seat angle adjustment to get your perfect riding position. For maintenance, keep the seatpost clean. Wipe it down after each ride to remove dirt and debris. Check the cable routing regularly to make sure it's not kinked or damaged. Also, check the bolts for tightness from time to time. If you notice any issues with the compression or the travel adjustment, it might be a good idea to take it to a professional bike mechanic. Enjoy a smooth and adjustable ride with your e*thirteen seatpost.
