Air piston removal tool for Fox 40 mm forks
For use in installation of Vorsprung Secus Learn More

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.
