Found out my torque wrench was lying to me by 8 ft lbs and I want to know who is actually right about re-calibration
I borrowed a beam style torque wrench from a retired guy named Hank at the shop in Sacramento last month just to double check my click type, and the clicker was reading 8 ft lbs heavy at 40 ft lbs on his tester. He swears by sending wrenches out every year no matter what, while the other old timer here says a click type is fine for 2 or 3 years if you never drop it and always back it off to zero. I looked up the spec sheets and most makers say 12 months or 5000 cycles, but I cannot find anyone who actually tracks cycles on a shop wrench that gets used all day. Here is my problem: sending 4 wrenches out at about $40 each plus shipping is real money, and I am not sure it buys me much when most of what I torque is stem bolts and cassette lockrings. But then I think about all the carbon bars and seatposts going out the door and it makes me nervous. So which side are you on, do you go by the yearly rule or do you test against a known good beam and only send it out when it drifts? And if you do test, what are you using as your reference?

I bought a cheap beam wrench off Amazon for $30 to use as my garage reference, so take that for whatever a stranger's opinion is worth. For what you're doing, stem bolts and lockrings, a beam check every few months is plenty and you only ship the clicker when it drifts past a few percent. Carbon bars are the one place I'd eat the $40, since a crushed bar costs a lot more than a calibration.
