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.
