ParkTool chain checker

Accurate professional chain checker to quickly check the wear (extension) of the bicycle chain. The correct position of the checker is fixed by pressing the chain roller onto the chain pin, i.e. as well as when stressing the chain by pulling on the chainring/pinion teeth. Also compatible with SRAM AXS chain.

The control touch indicates 3 levels of wear:

• 0% (ok)
• 0.5% (limit recommended by a number of manufacturers for 11-12 speed chains, including SRAM® T-Type, SRAM® Flattop™ and Shimano® XTR,®SRAM)
• 0.75% (limit for 5-10speed chains).

Made of stainless steel in the U.S.A. Follow the pictures on the package or watch the video to check.
