Park Tool CC-2 Chain Checker

What is it?  This is a tool that measures chain stretching. Over time, chains stretch, causing the drivetrain components to wear and cogs to "shark tooth." 

Why we love it?  We have found this tool to be the easiest of its kind to use. We use this for both the front and rear Pedicab chains.

Pro Tip!  Regularly checking the length of the chain wear, and replacing the chain when it becomes too worn will greatly increase the life of the drivetrain (and save money).

What are the options?  This tool comes in metallic blue.
