Giustaforza 1-8 - Torque wrench

The ideal tool for both professional mechanics and cycling enthusiasts, Giustaforza 1-8 torque wrench has a very small head, to operate in tight spaces. The DELUXE version is completed with cycling-specific bits in a practical wrap package.

• specifically designed for bicycle applications
• very easy to use
• extreme constructive quality for maximum reliability and durability
• very small, ‘non-ratcheting’ head, to operate in tight spaces
• no batteries to replace
• no plastic parts

CHARACTERISTICS:

Capacity from 1 up to 8 Nm

The Giustaforza 1-8 is especially attractive for very sensitive bolts. On those, where the right torque matters most, tightening values can be easily exceeded without the user knowing. Going as low as 1 Nm puts the Giustaforza 1-8 in a league on its own. In use, always refer to the torque values specified on technical documents or printed on the parts themselves.

Easy to use

1. Set the desired torque rotating the wrench end knob, reading the torque value on the scale (scale resolution is 0.25 Nm, integers and .5 on the left, .25 and .75 on the right). IMPORTANT: the thicker line on the dial should be centered on the desired value on the scale;
2. insert the appropriate bit (depending on the bolt you need to tighten);
3. using the tool, a loud ‘CLICK’ and a 5° free-movement tells when the torque has been reached;
4. always take the wrench to minimum torque value after use.

Minimal, fixed head

The simple, ‘non-ratcheting’ head has been designed to operate where space is limited, for example with some seat clamps. This small head is a unique asset to work in tight areas. Compatible with standard 1/4” bits.

Lightweight and compact

The light aluminum body keeps the weight below 140 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 145 mm.

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

Functional, linear in design and precise in any detail: Giustaforza 1-8 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. The absence of batteries or electronics increases its reliability. Each sample is checked and numbered as a single masterpiece.

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 Lugano (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 alone or as DELUXE version, equipped with a bicycle-specific bit set and a wrap pack.

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

Giustaforza is made in Italy.

FAQ

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.
