Problems with conventional dropper seatposts

  • Tubes overlapping too short and undersized bushings
  • High leverage forces lead to premature wear and bearing play
  • Common malfunctions: Worn bushings prevent the support from lowering smoothly.
  • Thin tubes with long strokes (200 mm+) bend backward up to 13 mm under load.
  • Noticeably elastic seating comfort and altered saddle angle
  • Bowden cables often get stuck during height adjustment and become damaged.
  • You need tools for height adjustment.
  • Excessive tightening torque on the seatpost clamp causes the seatpost to jam.

Integrated performance. No add-on parts.

    👎 Tube within tube within tube

    • The original retrofit concept was not questioned for over 20 years.
    • Telescopic seatposts are still screwed onto the bike with a seatpost clamp today.
    • Bowden cables can be easily damaged during adjustment.
    • Height adjustment is cumbersome and requires tools and expertise.
