. The home mechanics dream tool, the original Giustaforza gets now an even smaller head, to operate in tight spaces Capacity from 2 up to 16 Nmthis is the best torque range for precision bicycle applications and sensitive components. In use, always refer to the torque values specified on technical documents or printed on the parts themselves Features 10x25mm HEX2, HEX2 5, HEX3, HEX6, T10, T15, T20, T30, 316, PH13x100mm HEX4, HEX5, T251x100mm extensionHow to use Set the desired torque rotating the wrench end knob, reading the torque value on the scale scale resolution is 0.5 Nm, integers on one side, 0.5 on the otherInsert the appropriate bit depending on the bolt you need to tightenUsing the tool, a loud CLICK and a 3 free movement tells when the torque has been reachedAlways take the wrench to minimum torque value after use Minimal fixed headGiustaforzas simple, non ratcheting head has been chosen on purpose on this version, to facilitate the tightening of bolts where space is very limited like seatpost bolts parallel to the seatpost shaft in zero offset models. The head is now smaller than ever, to maximise this advantage Lightweightthe light aluminum body keeps the weight down to a record breaking sub 180g value, 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.A state of the art tool, built to lastfunctional, linear in design and precise in any detail shouldnt be a surprise to know that Giustaforza II 2 16 has been conceived and produced in Italy. The tool is hard anodized with laser etched iscriptions, and its built to last. The mechanical, click type functioning make the wrench extremely shock tolerant and the absence of batteries or electronics furtherly increase its reliability. Each sample is checked and numbered as a single masterpiece Calibration servicethe 4% tolerance is guaranteed for 5000 cycles 5000 clicks, then the wrench should be re calibrated. Calibration is a service we offer in our laboratories at the cost of 35 plus shipping expenses may vary depending on the countries check terms & conditions with the national distributor. After 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 BuyEffetto Workshop Tools from Chain Reaction Cycles, the World's Largest Online Bike Store.
