Vorsprung Secus - A better spring rate curve than coil?

Vorsprung Secus - A better spring rate curve than coil?

So what's that all about.

Well the Secus offers an increased negative chamber as well as solving the dilemmas of harsh progression and lack of mid-stroke support.


Some key details:

  1. Enlarged negative spring for small bump compliance
  2. Midstroke Support Valve boosts the midstroke spring rate for support, predictability, ride height
  3. Enlarged lower leg volume reduces overall progression whilst retaining volume spacer tuneability
  4. Weight - approximately 130g

This if the first and only air spring system to really come indistinguishably close to the linear spring rate of a coil fork for the entire first 2/3rds of its travel, with the advantage of a gentle end stroke progression to prevent bottoming without the “wall of force” harshness that excessively progressive springs create.

Three Stages of Control

By independently optimising the beginning, middle and end portions of the stroke, the Secus gives you the linear-to-progressive spring rate that coil springs and traditional air springs alike wish they had.
