TUNAP Sports Chain Brush Grunge

For chains, belts, and pinions • Three-sided cleaning • Removes stubborn oil and dirt residues

The TUNAP Sports Chain & Belt Brush was specially developed to clean drivetrains quickly, thoroughly, and gently. The three-sided chain jaw completely encloses the chain and cleans three sides simultaneously, while the long nylon bristles reliably remove stubborn dirt, oil, and grime from pinions, pulleys, and belts. Ideal for anyone who wants a clean, durable, and smooth-running drive unit—whether on a road bike, mtb, gravel bike, city bike, or electric bike.

Features of the TUNAP Sports Chain & Belt Brush

• Three-sided chain jaw – cleans the chain all around: inside, outside, and top simultaneously
• Long nylon bristles – ideal for pinions, pulleys, and belt drives
• Removes stubborn oil and dirt residue – perfect for thorough drivetrain cleaning
• Gentle on materials – safe for steel, aluminum, plastic pulleys, and belts
• Perfect for use with the TUNAP Sports Drive Cleaner – maximum cleaning power
• For chain drives (road bike, mtb, gravel, city), belt drives (Gates & similar systems), sprocket sets & pulleys, chainrings & idler pulleys

Why a chain & belt brush is indispensable

Dirt, oil, and moisture accumulate in the drivetrain and cause:

• increased friction
• faster wear
• noisy operation
• inefficient power transmission

The three-sided chain cleaner enables extremely efficient cleaning in the shortest possible time—significantly faster than with conventional brushes.

Application

• Apply TUNAP Sports Drive Cleaner to the chain/belt.
• Place the brush with the three-sided chain cleaner on the chain.
• Rotate the chain backward – dirt is automatically loosened.
• For pinions and rollers: Use nylon bristles.
• Rinse with water & re-lubricate the chain.
