For the high-torque jobs on a bike, from bottom brackets to cassette lockrings, the Giustaforza 10-60 Pro brings the same design and build quality as the smaller Giustaforzas to a 10-60Nm workshop wrench.

Highlights

• 10-60Nm range for bottom brackets and cassettes
• Reversible ratchet head with 3/8" square
• Calibrated for clockwise and anticlockwise tightening
• 3/8" to 1/2" adapter included
• Steel body with laser-etched markings, 950g, 370mm long

Set, click, done

Rotate the knob to the value on the scale, then push the square bar through the head to one side or the other to set the ratchet direction. A loud click and 3 degrees of free movement tell you the set torque has been reached.

Built for the workshop

The mechanical click action is highly shock tolerant, with no batteries, electronics or plastic parts to fail. Each wrench is individually checked and numbered.

Calibration

The +/- 4% tolerance is guaranteed for 5,000 cycles (5,000 clicks), after which Effetto Mariposa recommends recalibration; its calibration service extends the tolerance for another 5,000 cycles and returns the wrench with a calibration certificate. Store the wrench at its 10Nm minimum setting.

Compatibility & fit

Takes 3/8" drive sockets and tools, or 1/2" drive with the included adapter. Always follow the torque value specified by the component maker.
