With up to 180 mm of tool-free, infinitely adjustable travel, the ethirteen Vario Infinite dropper post was designed to make your rides better. Install it, adjust it and forget it.

  • Tool-free travel adjustments in +/- 5 mm increments with a max total of 30 mm can be made on the trail in seconds—without removing the post from the bike
  • Bigger keys reduce rotational play and make for longer service intervals

  • Saddle clamp design allows an extra 12 mm of fore/aft adjustment and up to 20° of seat angle adjustment
  • Cable actuated; compatible with internally routed frames
  • Minimum insertion: 150 mm; maximum insertion: 288 mm
