• HIGHLIGHTS:
  - the red anodized body makes it easy to find on a crowded work table
  - the stronger box makes it easy to pick/store bits
  - same outstanding technical specifications as the standard Giustaforza
• Ideal torque range, 2-16 Nm (17,7-141,6 inch pound
  this is the best torque range for precision bicycle applications and 'sensitive' components. 2 Nm is good for small aluminum screws, 16 Nm is enough for big M6 bolts used in some seatposts. A wider scale wouldn't allow the same precision at the range extremes. In use, always refer to the suggested (on technical documentation or on the part itself) torque values;
• Extremely user-friendly: set the maximum torque rotating the handle terminal, reading the torque on the tool-window (graduate scale with 0,5 Nm increments); insert the appropriate bit (depending on the bolt you need to tighten) using the tool, a loud 'CLICK' and a 3° free-movement tells when the torque has been reached

• Ready to use, with 16 bits included:16 bits are provided with the key, allowing to use the torque-wrench on almost any screw present on modern bicycles. A 70mm long '5' hex bit allows to tighten road-brake levers recessed bolt. All bits are manufactured from S2 special steel, with very high (62 Hrc) surface hardness, to ensure maximum durability;
• Lightweight & strong:
  the light aluminum body keeps the weight down to a record-breaking 169g per key, less than half the weight of heavy industrial wrenches often used for bicycles. This is paramount to get the right torqueing sensitiveness at low torque values, without mistaking the effort to hold the tool with the applied torque. Adjustment knob and bit-holder are made out of steel, to better stand daily use;
• Professional precision:
  torque tolerance is +-4%, according to UNI EN ISO 6789:2004 norm (calibration certificate with SIT reference is available upon request);
• A state-of-the art tool, made in Italy:
  functional, linear in design and precise in any detail: shouldn't be a surprise to know that Giustaforza 2-16Nm has been conceived and produced in Italy. The tool is hard-anodized with laser-etched iscriptions, and it's built to last. Each sample is checked and numbered as a single masterpiece.

Effetto Mariposa (which is Italian for butterfly effect) is devoted to providing bicycle mechanics and cyclists with the best-possible tools to work on modern bicycles.Knowing that many riders underestimate the smaller details and parts of their equipment, Effetto Mariposa targets both aspects of the "Butterfly Effect": by developing tools to prevent damages and create tiny winning advantages.
