Chain cleaning brush GEKO G03505 (manual bicycle chain brush, model 300)

The GEKO G03505 chain cleaning brush (model 300) is a manual bicycle chain brush designed to remove dirt, grease and debris from drive chains. Its compact design and multi-angle bristle arrangement allow access to chain links, rollers and side plates for routine maintenance before lubrication. The brush is intended for home bike care and workshop use to help prolong chain life and maintain consistent gear shifting performance.

Advantages

The brush combines a compact handheld body with densely packed bristles arranged to clean different parts of the chain without disassembly. Its manual operation requires no power source and provides precise control over cleaning pressure and contact angle. The tool is lightweight and easy to store, making it convenient for regular maintenance and periodic deep cleaning.

Suitable for

• Cleaning bicycle drive chains on road, mountain and hybrid bikes
• Pre-lubrication cleaning to remove grit and old grease
• Routine home maintenance and small workshop repairs

Key specifications

• Handheld manual brush with ergonomic grip for one-handed use
• Multi-angle bristle arrangement to reach links, rollers and side plates
• Compact dimensions for easy storage and portability
• Durable synthetic bristles suited for removing dirt and grease residues
• Suitable for regular cleaning before applying chain lubricant

How to use

Position the brush around the chain while the bicycle is stable, either on a repair stand or supported so the rear wheel can rotate freely. Hold the brush so the bristles contact the chain links and rotate the pedals backwards to move the chain through the brush. Apply steady, even pressure and repeat several times along the full length of the chain. For heavily soiled chains, use a degreasing agent compatible with bicycle components, then rinse and allow the chain to dry before applying lubricant.

Usage recommendations

Use the brush regularly as part of a maintenance routine: clean the chain after wet or dusty rides and before re-lubrication. Avoid excessive force that could damage seals or bearings; when using solvents, follow the solvent manufacturer's safety instructions and ensure proper drying before lubrication.
