La torque wrench It's much more than an accessory, especially if we contextualize the product in today's modern cycling world. Carbon and super-light alloys, extremely thin thicknesses and screws that work with equally small surfaces, materials with breaking loads that require great attention. The torque wrench is a precision instrument, but also a lifesaver capable of avoiding unpleasant inconveniences.
When we talk about precision mechanics, completely dedicated to the bike, the thought converges directly on the line of Mariposa effect. Staying within the scope of torque wrenches, let's delve deeper the new release of Giustaforza, designed and created specifically for the bike.
The new key of Effetto Mariposa
More than new, Giustaforza is a sort of natural evolution of a tool that's a symbol of the category, already present in the Effetto Mariposa catalog. By category, we're not referring exclusively to bicycle mechanics and industry professionals, but to the entire cycling segment. Giustaforza was the first real torque wrench designed for the bicycle, thanks to its design, thanks to the different members of the Giustaforza family. One precision mechanics tool developed by cyclists, for all types of cyclists.
Giustaforza Fixed, different from the version Pro Evo, has been improved and renewed. It has a single working direction, that is, draft (clockwise) and compared to the older version it is characterized by a rounded headIt is not a simple whim of form and design, but the solution makes working in tight spaces easier and preserves each component, eliminating any signs of friction or contact in the head. The head is fixed and without ratchet (precision and reduction of problems are gained, with the ¼ hexagonal housing for the inserts). The torque wrench has mechanical operation, there are no batteries or electronic components. It is made of metal: it is worth highlighting the total absence of plastic parts.
Visible graduated scale
La graduated scale for setting the Nm is clearly visible, positioned on the side that remains external when working on the small parts. The base, which also corresponds to the force adjustment ring, has been further improved. Easy to rotate, offers optimal grip even when hands are dirty, or wear gloves.
La scale increases/decreases by 0,1 Nm at a timeAnother very important factor to consider when choosing a specific torque wrench for your bike is the ability to work precisely even at low tightening torques (Giustaforza Fixed range is 1/15 Nm). Not infrequently, when working on screws and small parts made of ergal, titanium and carbon, the tightening limit drops exponentially: not a trivial matter.
Many torque wrenches, of good quality, but developed for medium/large-sized mechanics, do not reach and be precise at the lowest loads. Another added value is the click, which is perfectly felt when the set torque value is reached, as well as the free movement of 3° which further establishes the limit reached. Precisely from the point of view of use, this latest version is in some ways easier to use, more substantial and thanks to a more voluminous terminal it grips better.
Size, low weight and high hardness of the elements
190 grams net of inserts, for a length of 173 millimetresThe accuracy of the torque wrench is guaranteed for 5.000 cycles and you can register/recalibrate the instrument.
The Deluxe version also comes complete with all the useful inserts for the bike. They are made of steel with a hardness of 62 HRC (Rockwell scale). If we want to make a comparison, the hardest modern steel alloys have hardness values between 64 and 68 HRC, a comparison which once again categorizes the high quality of this torque wrench.
Interesting initiative
Thanks to the collaboration with us at bici.PRO, Effetto Mariposa has activated a discount percentage of 20% and dedicated to our readers. You can take advantage of this initiative directly from the Effetto Mariposa website, inserting the wording BICIPRO20.
