The Giustaforza (GF) torque wrench is a precision instrument. The Giustaforza wrench is guaranteed accurate +/- 4% for the first 5000 clicks. Thereafter its accuracy will eventually degrade to +/-10%.
Unless you've neglected to return the wrench to its lowest tension setting after use, you probably don't have to consider recalibration. Five thousand clicks is a lifetime of use for most users.
However, if you're a bicycle shop mechanic and you use this wrench all day everyday, or if you've ever forgotten to un-tension your wrench, you can have it re-calibrated following the two steps below.
Re-calibration price: $50
Price includes certified re-calibration, handling, and guaranteed return shipping throughout the U.S.
