🔍 Rohloff Chain Wear Indicator: A Reliable Tool for Measuring Chain Wear Review

Overstretched chains can ruin rear cassette teeth. This product is easy to use and has two scales/sides, one for chains used with titanium cassette sprockets and one for all steel sprockets. Simple instructions. Recommended by Lennard Zinn.

Campagnolo recommends changing the chain when the distance between 6 links is 132.6 mm, this corresponds to an elongation of 0.6 mm for 6 links. The chain should be replaced when it stretches more than 0.1mm per link and this is Campagnolo's suggestion. Interestingly this high quality tool also uses 6 links to measure and has 2 measurements, one with 0.1mm stretch per link marked both 0.1mm and 0.075mm which Roholoff says should be used for alloy gears . I use .075 chain which is cheaper than…

It's hard to put into words, as I've learned from previous discussions on the web, but I'll try: this type of wear indicator pushes the two chain rollers in opposite directions, so not only does it measure how the chain elongates due to wear, it does that too Play measured between roller and pin…
