CC-4.2 Chain Gauge

<p data-start="152" data-end="557">The CC-4.2 chain checker from ParkTool is a precise measuring tool for quickly and reliably checking chain wear. An elongated chain not only impairs shifting performance, but can also wear out the cassette and chainrings prematurely. With this chain tester, you can recognize early on when it makes sense to replace the chain and thus protect your entire drivetrain.</p> <p data-start="559" data-end="1001">The drop-in design makes it particularly easy to use. The laser-manufactured tester measures a longer section of the chain and is positioned at three strategic points. This accurately measures the actual wear and makes assessment much easier. The tool indicates precisely when the chain has reached 0.5 %, 0.75 % or 1.0 % wear - values at which most manufacturers recommend replacement.</p> <p data-start="1003" data-end="1248">The chain tester is compatible with 5-speed to 13-speed derailleur chains, including modern systems such as SRAM&reg; T-Type, SRAM&reg; Flattop&trade;, Shimano&reg; XTR&reg; 12-speed and Campagnolo&reg; Ekar&trade; 13-speed. Single-speed chains can also be checked reliably.</p> <p data-start="1250" data-end="1514">The CC-4.2 chain tester from ParkTool impresses with its ease of use, high measuring accuracy and broad compatibility - an indispensable tool for anyone who wants to optimize the service life of their drivetrain and reduce maintenance costs in the long term.</p>
