Feedback Sports Digital Chain Gauge

Feedback Sports had this shop-grade digital chain gauge on display to better tell when a chain really needs a replacement so that shops have a better way to give accurate measurements and consumers aren’t replying on simple rules of thumb or replacing chains prematurely. It measures chain stretch up to 2.5mm in .01mm increments, yielding the most precise measurement of stretch out there.

    Obviously needed for something as critically precise as a bicycle chain.

    If this measures “chain wear” like the standard Rohloff/Park chain tools, the methodology is faulty DESPITE its precision. Here’s a good article that explains why:

    Just another gimmick to make money!

    Take a ruler and measure from pin to pin. It should be 12 inches exactly anything over is worn.

    It doesn’t matter what chain 12 inches exactly.

    I prefer to hold a tea bag over my open palm. After carefully observing its motion for several minutes, I then head over to my occult library and pore over the antique wisdom contained within to divine the various meanings and portents. Only then do I feel adequately prepared to head to the bike shop to spend $11 on a new 7sp chain. I’m actually selling this foolproof bike chain measurement ritual, $99.99+tax.

    beezleboss. If it’s such a gimmick….why are dealers snapping them up from Feedback. The Rohloff, Park Tool and other gravity measuring ones are all subjective depending on the pressure a mechanic applies. Dealers have commented they’ll have 3 different gauges and get 3 DIFFERENT readings. They’re utilizing this tool to take the guess work out of it and state they’re thrilled to provide more accurate readings and superior customer service. It garners even greater loyalty and credibility. Unless any of you have tried one…. it’s very short sighted to diss this product and your opinions are mis-leading to the public. I’d rather have an accurate reading than let the chain wear hit .7 .8 or greater and then your wallet will love buying a new cassette and possibly new front rings as well. As for the 12 inch measurement…. you talk to pro and neutral support mechanics at cross races, road races, mtb races and they’ll tell you they do NOT go by or trust this method. Any one of you should take your bike to a dealer with a Feedback gauge and see what they show you and then if they have the gravity units compare the findings.
