## Description

desertcart.com : Park Tool CC-4.2 Bicycle Chain Wear Checker : Sports & Outdoors

Review: An affordable and reliable chain checker if trying to minimize drive-train wear - I recently got into chain waxing (Silca) and use the CC-4.2 to make sure my chain isn't getting "stretched" (there is no chain stretch, only chain wear). Staying on top of chain wear will extend the life of my cassettes and save me money. This is a simpler, cheaper and more accurate tool than Park's more sophisticated (looking) CC-2 chain checker. The CC-2 looks like it would be more dynamic, but typically falsely says a chain is worn if the pins become deflected too far. My bike shop uses a CC-2 and replaced my chain prematurely for no reason except that the CC-2 is recognized as a bad chain checker. Save yourself some money and replace chains at an appropriate wear level (not prematurely) with this tool!
Review: Good Checker - Simple and does the job well.
