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.
Send your GF torque wrench via trackable shipment to:
Cantitoe Road
2106 Rollingwood Drive
Fort Collins, CO 80525
After you have your Giustaforza ready to ship, buy the recalibration (i.e., add this re-calibration item to your cart), checkout., and then send us your wrench.
Make sure you provide us with your correct return shipping address during the checkout process, so that we can return the recalibrated wrench to you.
