Effetto Mariposa GIUSTAFORZA 1-15 PRO EVO DELUXE Key

Intended for professional users, the Giustaforza 1-15 Pro Evo torque wrench has a smooth oil finish and is calibrated for bidirectional tightening. The Deluxe version is completed with cycling-specific inserts and comes in a practical wrap-around package.

Specifically designed for cycling applications

Very easy to use

Extreme build quality for maximum reliability and durability

Calibrated for clockwise and counterclockwise tightening

reversible ratchet head

micrometer scale to set the desired torque value (0.1 Nm)

No batteries to replace

No plastic parts

Capacities from 1 to 15 Nm

This is the best torque wrench for precision applications on bicycles and "sensitive" components. When using it, always refer to the torque values specified in the technical documentation or printed on the parts themselves.

Easy to use

Set the desired torque value by turning the self-locking black dial: pull and rotate to set the torque value, release to lock. The resolution of the scale is 0.1 Nm;

insert the appropriate bit (depending on the bolt to be tightened);

during tightening a strong 'CLICK' and a free movement of 3° indicate when the torque value has been reached;

after use, always set the wrench to the minimum torque value (1.0 Nm).

If in doubt, always refer to the instruction manual.

Ratchet head

For greater productivity in professional applications, Giustaforza 1-15 Pro Evo has a very small ratchet head, with a 1/4" square drive (1/4" square/hexagonal adapter supplied, to be able to use standard bits). IMPORTANT: The ratchet action can be reversed by turning the black crown surrounding the silver pusher in the center of the head.

Lightweight and compact

The lightweight aluminum body keeps the weight under 210 g, less than the met weight of other torque wrenches in this torque range. This is crucial to achieve the right feedback at low torque values, without confusing the effort required to hold the tool with the torque applied. Its overall length is 173 mm.

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

Functional, linear in design and precise in every detail: Giustaforza 1-15 Pro Evo has a body made of anodized aluminum duro with laser-engraved lettering, and is built to last. The mechanical snap-on operation makes the key extremely resistant to shocks and the absence of batteries or electronics increases its reliability. Each piece is checked and numbered as a single masterpiece. Giustaforza 1-15 Pro Evo meets the quality standards DIN ISO 6789 and ASME B 107.300-2010.

Calibration Service

The tolerance of +-4% is guaranteed for 5000 cycles (5000 'clicks'), then the wrench will have to be recalibrated. Calibration is a service that we offer in our laboratory in Bioggio (Switzerland) at a cost of 50 CHF. With each calibration, the tolerance of +-4% to the nominal value will extend for 5000 cycles. After calibration, the key will return to the customer with a calibration certificate.

Available versions

The key is available on its own or in the Deluxe version, equipped with a set of bits specific for bicycles.

The bits include a 100 mm extension, three 100 mm bits (hex 4, hex 5 and T25) plus several other standard length Torx and hex bits (25 mm). This covers all the needs of high-end groups. All drill bits are made of special S2 steel, with very high surface hardness (62 Hrc), to ensure maximum durability.

Detail of the bits:

10x25 mm (HEX2, HEX2.5, HEX3, HEX4, HEX5, HEX6, T10, T15, T20, T30, -3/16, +PH1)

3x100 mm (HEX4, HEX5, T25)

1x100mm (extension)
