Review on Optimized Park Tool CC-3.2 Chain Wear Indicator Tool by Mark Clark

This is the most specific tool you can buy. It just measures the condition of your road bike chain and tells you if it's time for a chain change. That's all. He can't do anything else. And god knows I tried. I tried to make prison scissors out of it: fail; blunt as a butter knife. I tried using two as chopsticks at my local Vietnamese restaurant Pho: no cubes. I tried to sell them as metal back scratchers: a person with a severe back itch bought them but ended up using them for their intended purpose: to see if your bike chain was stretched beyond its useful life. And that's why it's magic! What I really like about this tool is that it measures 0.5″ (and also 0.75″), which is more accurate for high-end road bikes. I like to swap out the chain if the 0.5" indicator slips too deep into the chain links. It's a low-tech tool that's actually a bit of a genius. Every serious or semi-serious Fred should have one.
