ARLEN NESS Spider Rotor Adaptor — 320 mm, 5-bolt, 3.25" bolt circle, fits ARLEN NESS cartridge hubs

Precision CNC-machined rotor carrier for floating spoke-mount brake rotors on cartridge-style wheel hubs.

Forged then precision machined into a lightweight carrier that follows the sculpted lines of cartridge hubs and reduces mass.

Coped cut-out design mirrors the sculpted hub lines and trims excess material for optimized weight and clearance.

With an installed 320 mm spoke-mount floating rotor it forms a lightweight complete performance rotor for front applications.

Mounts to standard 5-bolt motorcycle wheels with a 3.25" bolt circle and enables use of 320 mm factory touring spoke-mounted floating rotors on custom wheels.

Intended for use only on wheels with cartridge-style hubs and specific rim applications; verify compatibility before installation.
