CHARACTERISTICS:

Capacity from 1 up to 15 Nm

This is the best torque wrench for precision bicycle applications and ‘sensitive’ components. In use, always refer to the torque values specified on technical documents or printed on the parts themselves.
Please note: Giustaforza 1-15 Pro is calibrated for clockwise tightening. If you also need counter-clockwise calibrated tightening, this feature is available with our Giustaforza 1-15 Pro Evo.

Easy to use

1. Set the desired torque value rotating the self-lock black dial: pull and rotate to set the torque value, release to lock it. Resolution of the scale is 0.1 Nm;
2. insert the appropriate bit (depending on the bolt you need to tighten);
3. while tightening, a loud ‘CLICK’ and a 3° free-movement tells when the torque value has been reached;
4. always take the wrench to the minimum torque value (1.0 Nm) after use.

When in doubt, always refer to the instruction manual.

Ratcheting head

For a higher productivity in professional applications, Giustaforza 1-15 Pro has a very small ratcheting head, with 1/4″ square (1/4″ square/hex adapter provided, to be able to use standard bits). IMPORTANT: the ratcheting action can be reversed by rotating the black crown surrounding the silver button in the center of the head.

Lightweight and compact

The light aluminum body keeps the weight below 210 g, less than half the weight of other torque wrenches in this range of torque. This is paramount to get the right feedback at low torque values, without mistaking the effort to hold the tool with the applied torque. Its overall length is 173 mm.

A state-of-the art tool, built to last

Functional, linear in design and precise in any detail: Giustaforza 1-15 Pro has a hard-anodized aluminum body with laser-etched inscriptions, and it’s built to last. The mechanical, click-type functioning makes the wrench extremely shock tolerant and the absence of batteries or electronics increase its reliability. Each sample is checked and numbered as a single masterpiece. Giustaforza 1-15 Pro meets DIN ISO 6789 & ASME B 107.300-2010 quality standards.

Calibration service

The +-4% tolerance is guaranteed for 5000 cycles (5000 ‘clicks’), then the wrench should be re-calibrated. Calibration is a service we offer in our laboratory in Bioggio (Switzerland) at the cost of 50 CHF. With every calibration, the tolerance of +-4% over nominal value will extend for 5000 cycles. After calibration, the wrench will return to the customer with a calibration certificate.

Available versions

The wrench is available by itself or as Deluxe version, equipped with a bicycle-specific bit set.

Bits include a 100 mm-long extension, three 100 mm-long bits (hex 4, hex 5 e T25) plus several other Torx and hex bits in standard length (25 mm). That covers all the needs of high-end groupsets. All bits are manufactured from S2 special steel, with very high (62 Hrc) surface hardness, to ensure maximum durability.

Detail of bits:

• 10x25mm (HEX2, HEX2.5, HEX3, HEX4, HEX5, HEX6, T10, T15, T20, T30, -3/16, +PH1)
• 3x100mm (HEX4, HEX5, T25)
• 1x100mm (extension)

FAQ

What is the torque range and resolution of the Giustaforza 1-15 Pro torque wrench?

The Giustaforza 1-15 Pro torque wrench offers a torque capacity ranging from 1 up to 15 Nm, making it ideal for precise bicycle applications and sensitive components. Its micrometric scale allows users to set torque values with a resolution of 0.1 Nm, ensuring accurate tightening according to specified torque requirements.

Can the Giustaforza 1-15 Pro torque wrench be used for both clockwise and counter-clockwise tightening?

The Giustaforza 1-15 Pro torque wrench is calibrated for clockwise tightening. However, if counter-clockwise calibrated tightening is required, users can opt for the Giustaforza 1-15 Pro Evo, which offers this feature. It's essential to ensure the correct calibration for the specific tightening direction to maintain accuracy and prevent over-tightening or damage to components.

What materials are used in the construction of the Giustaforza 1-15 Pro torque wrench, and what quality standards does it meet?

The Giustaforza 1-15 Pro torque wrench features a lightweight yet durable aluminum body, weighing below 210 g. Its hard-anodized aluminum body with laser-etched inscriptions ensures longevity and precision in any detail. The wrench meets DIN ISO 6789 & ASME B 107.300-2010 quality standards, guaranteeing reliability and performance for professional users.

Can I use Giustaforza only for tightening (clockwise) or also for unscrewing (counter-clockwise)?

• Giustaforza 1-8: while we suggest to use it for its intended purpose, calibrated tightening, the wrench can also be used to unscrew, there are no negative effects on the calibration;

• Giustaforza 10-60 Pro: while we suggest to use it for its intended purpose, calibrated tightening, the wrench can also be used to unscrew, after having reversed the operation of the ratchet using the square through pin, there are no negative effects on the calibration;

• Giustaforza 1-15 Pro & Pro Evo: while we suggest to use it for its intended purpose, calibrated tightening, the wrench can also be used to unscrew, after having reversed the operation of the ratchet, there are no negative effects on the calibration;
  

Is the Giustaforza wrench calibrated for clockwise and also anti-clockwise tightening?

Even if all Giustaforza wrenches also work counter-clockwise, not all of them are calibrated in this direction.

• Giustaforza 1-8: NOT CALIBRATED for anti-clockwise tightening. The wrench can also be used to unscrew, but it does not click at the set torque;

• Giustaforza 10-60 Pro: CALIBRATED for anti-clockwise tightening (clicks at the set torque).

• Giustaforza 1-15 Pro: NOT CALIBRATED for anti-clockwise tightening. The wrench can also be used to unscrew, but it does not click at the set torque;

• Giustaforza 1-15 Pro Evo: CALIBRATED for anti-clockwise tightening (clicks at the set torque).
  

At what torque value should I set the Giustaforza wrench, when I'm not using it?

The torque wrenches must be stored with the minimum torque value set.

• Giustaforza 1-8: 1 Nm.

• Giustaforza 10-60 Pro: 10 Nm.

• Giustaforza 1-15 Pro & Pro Evo: 1 Nm.
  

How does the Giustaforza torque wrench indicate that the correct torque has been reached during use?

The Giustaforza features a user-friendly mechanism to indicate the correct torque. When you reach the desired torque, the wrench emits a loud 'CLICK' sound, and there's a 3° free movement.

Could you explain the calibration process for the Giustaforza torque wrench and how often it should be calibrated?

The Giustaforza torque wrench comes with a +-4% tolerance, which is guaranteed for 5000 cycles or 'clicks.' After this, it should be re-calibrated. The calibration service is available in Bioggio, Switzerland, and costs 50 CHF. With each calibration, the tolerance of +-4% over the nominal value will extend for another 5000 cycles. After calibration, the wrench is returned to the customer with a calibration certificate.
