Review: A necessity for regular maintenance - My friend recommended this after he found out they make a bicycle version of the brush he has for his motorcycle. I also have the Park Tool chain cleaner but I use this brush for regular simple cleaning to keep the bike running smooth until I do a deep wash and clean once in a while. Well worth the price and will buy another one if it breaks Review: Easy and Effective - Simple and effective. I don't like reusing master links over and over and this tool is a great help in decreasing/cleaning y out r drive train without having to remove the chain. ## Features - Cleans the Entire Drivetrain: Designed to scrub chains, chainrings, cassettes, jockey wheels, and derailleurs for a more thorough clean. - Two Brushes in One Tool: Horseshoe-shaped bristles wrap around chains and gears, while long straight bristles reach tight spots like cassettes and derailleurs. - Cuts Through Grease & Grime: Stiff nylon bristles easily break up built-up dirt and oily residue for faster, more effective cleaning. - Works With or Without Degreaser: Use with water for light cleaning or pair with Finish Line degreasers for deeper drivetrain maintenance. - Simple Maintenance, Better Performance: Regular cleaning helps keep shifting smooth and extends the life of drivetrain components. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000BS02LS | | Best Sellers Rank | #44,117 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #21 in Bike Cleaning Tools | | Brand | Finish Line | | Brand Name | Finish Line | | Capacity | 1 fluid ounces | | Container Type | Bucket | | Customer Reviews | 4.5 out of 5 stars 1,849 Reviews | | Global Trade Identification Number | 00036121680906 | | Included Components | Cleaning Tools | | Item Form | Liquid | | Item Highlight | Dual-Brush Cleaning - Comfort Grip - Extends Drivetrain Life - Deep Cleans Chains & Gears | | Item Weight | 0.1 kg | | Manufacturer | Finish Line | | Material Type Free | Chlorine Free | | Model Number | G50006601 | | Number of Items | 1 | | Part Number | FIN-A-TOS027 | | Recommended Uses For Product | gears; chain; and other bike components | | Scent | Unscented | | Size | 1 Count (Pack of 1) | | Special Features | Portable | | Specific Uses For Product | Cleaning Tools | | Surface Recommendation | Metal, Plastic | | UPC | 370114978282 036121680906 352083856075 374528457135 361216809062 370114977155 | | Unit Count | 1 Count | | Warranty Description | Limited Warranty | ## Product Details - **Brand:** Finish Line - **Item Form:** Liquid - **Scent:** Unscented - **Specific Uses For Product:** Cleaning Tools - **Unit Count:** 1 Count ## Images ![Grunge Brush Bike Chain Gear Cleaner Dual-Sided Bristles - Image 1](https://m.media-amazon.com/images/I/81H+PCj09cL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A necessity for regular maintenance *by D***D on July 1, 2026* My friend recommended this after he found out they make a bicycle version of the brush he has for his motorcycle.
