CYLION Extended Bicycle Disc Brake Rotor Contamination Shield with Flexible PVC Panel for Chain and Cassette Cleaning and Maintenance

Disc rotor shield for drivetrain cleaning

This CYLION shield is positioned behind the rear cassette to separate the drivetrain cleaning area from the disc brake rotor. Its extended flexible panel is shown during chain and cassette washing. It helps intercept cleaning splashes while giving access to the drivetrain; careful cleaning and correct positioning remain necessary.

Extended PVC panel and reference dimensions

The product information identifies PVC construction and reference dimensions of approximately 51 × 33.5 × 0.05 cm. The 0.05 cm thickness equals 0.5 mm. The central opening and side slit allow the panel to be positioned around the rear hub area as demonstrated in the photographs.

Positioning and cleaning workflow

Use the illustrated slit and opening to position the shield between the cassette and rotor without forcing it against bicycle parts. Check drivetrain and wheel clearance before turning the cranks by hand for cleaning. Keep the bicycle stationary and follow the bicycle, brake and cleaning-product instructions.

Cleaning and storage

The source shows the panel being rinsed after use. Remove residue and allow it to dry before storage. Inspect the panel and opening for damage before reuse, and check the rotor and brake area after drivetrain cleaning. The shield does not replace correct brake-cleaning procedures.

Included item and demonstration accessories

One extended CYLION P20 disc rotor contamination shield is supplied. Brushes, chain tools, spray bottles, cleaners, lubricants, bicycles and wheels shown in supplier demonstrations are not included. This listing is for the empty cleaning accessory only.
