A Time & Money Saver
A worn chain damages the gears and rear derailluer. Modern bicycles have chains that are thinner and wear out quicker than single speed chains. This easy to use tool rapidly and accurately checks the chain wear. Repair-it-yourself bicyclists should consider having a chain checker in their toolbox.

Good for filling with oily contents
Doesn't leak when filled with coconut oil based mixtures. Softens quickly if held in mouth, especially handy if throat is tender.
