The Giustaforza 1-15 Pro and Giustaforza 1-15 Pro Evo torque wrenches are designed for precision bicycle maintenance, offering reliability, durability, and ease of use. Below is a streamlined overview of their key features and step-by-step usage instructions.

How to Use the Giustaforza 1-15 Pro & Pro Evo

1. Set the Desired Torque

• Pull and rotate the self-locking black dial to adjust the value, then release to lock it.

• The scale resolution is 0.1 Nm for precision.

2. Insert the Appropriate Bit

• Select the correct bit and insert it into the 1/4” square drive (adapter included for hex bits).

3. Tighten Until the Click

• Turn the wrench while tightening.

• A loud ‘CLICK’ and 3° free movement indicate the torque value has been reached.

4. Reset to Minimum After Use

• Always return the torque setting to 1.0 Nm to maintain accuracy over time.

5. Reversing the Ratcheting Head (Pro & Pro Evo models)

• Rotate the black crown around the black button with silver torx screw in the head center to switch directions.

6. Calibration Service

• After 5000 cycles, recalibration is recommended to maintain ±4% tolerance on nominal value.

• Service is available in Bioggio, Switzerland, for 50 CHF (see here).

Key Features

These torque wrenches provide a torque range from 1 to 15 Nm, ideal for sensitive bicycle components. The micrometric scale with 0.1 Nm resolution ensures precise adjustments, while the mechanical click-type mechanism eliminates the need for batteries, enhancing reliability. Each tool maintains a ±4% tolerance on nominal value for 5000 cycles before requiring recalibration.

For enhanced usability, the Giustaforza 1-15 Pro features a reversible ratcheting head, allowing for faster tightening. The Pro Evo model takes it further with an additional bi-directional calibration, enabling both clockwise and counter-clockwise controlled tightening.

Both models are built with a hard-anodized aluminum body, making them lightweight (under 210 g) and compact (173 mm in length). The Pro Evo version features a slick oil finish for a premium look and added durability.

The Deluxe version includes a cycling-specific bit set made of S2 special steel (62 HRC hardness) for long-lasting performance. It comes with a 100 mm extension and various Hex and Torx bits, covering all high-end groupset needs.

Conclusion

The Giustaforza 1-15 Pro & Pro Evo torque wrenches offer precision, durability, and ease of use for professional bicycle maintenance. Whether you need the reversible ratcheting head of the Pro or the bi-directional calibration of the Pro Evo, these tools provide the accuracy and reliability required for high-end cycling applications.
