If you have a Debonair C1 air spring for RockShox Lyrik/Pike, a replacement 35 mm Debonair this B1-style sealhead is now available. The C1 sealhead effectively shortens the air shaft and reduces/eliminates the pneumatic topout control present in the B1/B2 air shaft assemblies. While the Secus can be physically attached to a C1 Debonair air shaft assembly, it will reduce your travel and may top out noticeably loudly. We strongly recommend replacing the C1 sealhead with a B1 sealhead.Learn More

For the first time, Vorsprung has created an air spring with a truly better spring rate, everywhere in the travel, than a coil. The Secus upgrade delivers the first and only single crown 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.
This version of the Secus fits Fox 32, 34 & 36 mm stanchioned forks & Marzocchi Z1 2019+ forks (see Compatibility info). Also available for RockShox & Fox 38/40 mm forks. Learn More

Good suspension should be stable and supportive while being planted, yet playful. It should follow the ground to maximise traction and comfort, while eating bumps at low and high speed. It needs to stay smooth, controlled and always predictable with no bad habits.
