Review on 🔍 Rohloff Chain Wear Indicator: A Reliable Tool for Measuring Chain Wear by Kevin Schnitzer

There is a problem with this tool and its imitators, Park, Sette and others, which consistently create premature wear on still serviceable chains. and my dear darling, and has been for a long time. 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 (where play is always present, even with a new chain, but play is not consistent between brands and even chain models). For a good graphical representation of the problem with this chain wear indicator theme, use your favorite search engine to find "pardo chain wear gauge tools" (pardo,net is a host site, not a chain gauge retailer or manufacturer). With this tool, I keep getting a "no travel" reading when the chain is a little over half its actual wear limit. So far the only wear indicator I know of (but don't own) that measures chain wear correctly is the Shimano TL-CN41 chain wear indicator. It uses three teeth, two of which push two chain rollers in the same direction (much like a cassette or chainring) and check the gap between them. With this approach, the gauge only measures chain elongation and roller sag is irrelevant. (It is assumed that roller sag is the same for every roller in a chain, but this assumption is just as true when the chain is brand new as it is when it is worn.) My own method is the "12 and 1/16 rule". and requires only an accurate steel ruler.. The distance between two chain pins is exactly 1/2" on a new chain, or 12" when measured across 24 links. Once the 24 links have reached 12-1/16" should the chain can be replaced without damaging the sprockets and sprockets of the cassette. OK". From that point of view, using this tool will keep your transmission in tip-top shape. But you'll be spending almost 2x more to replace the chains. -- after all, I'm a big Rohloff fan and there's no question, that the Caliber is a precision engineered and built instrument, but if it measures the wrong thing, all else is for naught.
