ParkTool CC-3.2 Kettenverschleiß-Indikator-Werkzeug

Bought this tool to keep track of chain wear. Previously I had been using my vernier calipers but this is just so much more convenient. Its designed on one side to indicate 0.5% wear and on the other side to indicate 0.75% wear. The idea being you change your chain when its 0.5% worn but no more than 0.75% worn. It works perfectly on my Shimano Ultegra R8000 11 speed drive train setup. Robust, well designed and well made like all Park Tool products.

This seems fairly pricey for what it is, in fact I did order a cheaper one which failed to arrive (refund given). However I'm glad in a way to add this to my collection of Park tools. Usual Park quality, dead simple to use and really the definitive way to check chain wear. In a way this can save money in the long term, either encouraging you to buy a new chain before it wears the sprockets or even maybe stopping you from replacing a chain prematurely. Tempting though it is to knock off a star due to the high cost that would seem somewhat unfair as I knew the price and simplicity of item when ordering. I should have bought one years ago.

Finish isn't great but seems precise enough for a simple tool.

Works

Cheap but high quality A must for any bike ower

Does as it should checks the chain length and is made from a strong steel and was pretty cheap

this gadget already saved me money. Bike shop was saying I needed to change the chain to not wear out my gears. A quick check showed that the chain is far from worn out and has some life left in it. Great to be able to identify when I need to really change the chain (and not get connd by rouge bike mechanics)

Useful tool to have around when maintaining bikes. Park tool quality can't go wrong. Good price too
