Giustaforza 1-15 Pro Evo Deluxe

The Giustaforza 1-15 Pro Evo is the ultimate evolution of Effetto Mariposa's well-known torque wrench, specially designed for professional mechanics and demanding bicycle specialists. The key difference compared to the standard Pro version is the innovative bidirectional ratcheting head: this allows you to tighten both right-hand and left-hand threads with extreme accuracy to the correct torque.

Features of the Giustaforza 1-15 Pro Evo:
- Can measure torque and tighten in both directions (both clockwise and counterclockwise). This is ideal for specific bicycle components with left-hand threads, such as certain pedals or bottom brackets.
- Perfectly tuned for the most sensitive (carbon) bicycle components and high-end groupsets.
- Equipped with a 1/4" square drive (including a 1/4" square-to-hex adapter for standard bits) to work smoothly in tight spaces.
- Exceptionally fine-tuneable in 0.1 Nm increments for maximum accuracy.
- Weighing only approximately 200 grams with a total length of 173 mm, the wrench fits comfortably in the hand. This prevents confusing the holding force with the tightening torque.
- Operates with a reliable mechanical click mechanism. No batteries or fragile electronics required.

Easy to use:
Pull the black knob at the bottom, turn to the desired value (graduation per 0.1 Nm), and release to lock.
Choose the correct bit and set the desired direction of rotation (left or right) on the ratcheting head.
While tightening, a distinct "CLICK" and a free movement of 3° instantly indicate that the set torque has been reached.
Always reset the torque wrench back to its minimum value (1.0 Nm) after use to relieve tension on the internal spring.

Built for a long service life
The Giustaforza 1-15 Pro Evo features a robust, hard-anodized body with laser-engraved markings. Each unit is individually checked, numbered, and delivered with a certificate. Complies with the strict standards of DIN ISO 6789 & ASME B 107.300-2010.

Calibration service
Accuracy (tolerance of ±4%) is guaranteed for up to 5,000 cycles (clicks). After that, the wrench can be recalibrated via Effetto Mariposa's laboratory in Switzerland, returning to you with a new certificate.
