Problems with conventional dropper seatposts

  • Too short overlap of the tubes leads to extreme leverage forces on the bushing.
  • Poor-quality and undersized bushinges wear out easily.
  • Worn bushinges create radial play and lead to self-locking.
  • The seatpost is harder to lower and no longer lowers with reliable reliability.
  • Thin tubes in combination with long travels (200 mm+) flex 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.
  • The double telescoping limits the adjustment range of the Seatpost.
  • If a telescopic seatpost has too much or too little travel, it must be replaced.
  • Thin and long telescopic standpipes limit the maximum permissible rider weight.

Integrated performance. No add-on parts.
