Abbey Bike Tools

LL Chain Wear Tool

Precision, durability, and accuracy—the hallmarks of the Abbey Bike Tools LL Chain Wear Tool. Designed for pro mechanics and perfectionist home wrenchers alike, this CNC-machined tool delivers exact chain wear measurements for every ride, from road to gravel to MTB. It’s crafted in Bend, Oregon, with the level of precision that’s made Abbey Tools a legend in the workshop.

Unlike many wear gauges, the LL Chain Wear Tool measures from the center of the chain roller, giving a truer picture of your chain’s condition. It even checks lateral wear and play—a critical factor for today’s wide-range 1x drivetrains where chain angles can accelerate wear. Compatible with nearly every chain on the market, including SRAM Flat Top chains, this tool is the go-to for anyone who wants to keep shifting crisp and drivetrains lasting longer.

• CNC-machined aluminum for unmatched accuracy and long-term durability
• Measures chain elongation from the roller center—the most precise way to detect wear
• Assesses lateral play to monitor 1x drivetrain wear patterns
• Compatible with all chain types, including SRAM Flat Top
• Proudly made in Bend, Oregon, USA

For riders who demand the best from their tools—and their bikes—the Abbey LL Chain Wear Tool delivers professional-level accuracy in every measurement.
