The Torque Wrench Details
Ideal Torque Range, 2-16 Nm*
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 Torque Wrench
- Set the maximum torque rotating the handle terminal, reading the torque on the tool-window (Graduated 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
13 Bits Included
- 25mm bits (S2 steel)
- 2, 2.5, 3, 6
- T10, T15, T20, T30
- - 3/16
- + PH1
- 100mm bits (S2 steel)
Lightweight & Strong Wrench
The light aluminum body keeps the weight down to a mere 168g per wrench. A lightweight tool is critical for sensitivity at low torque values. With heavier wrenches, it's easy to mistake the effort to hold the tool with the applied torque. Adjustment knob and bit-holder are made of steel, to better stand daily use.
Professional Precision Torque Wrench
Torque tolerance is +-4%, according to UNI EN ISO 6789:2004 norm (calibration certificate with SIT reference is available for a new torque wrench upon request for an additional cost of $50).
Wrench Calibration Service
After 5000 cycles (5000 'clicks'), the GF wrench should be re-calibrated. Calibration is a service we offer in our laboratories at the cost of $50 plus $9.95 shipping and handling. After every calibration, the tolerance of +/-4% over nominal values is guaranteed. After calibration, the wrench will return to the customer with a calibration certificate.
A State-of-the-Art Tool
Made in Italy, functional, linear in design, and precise in every. This precision tool is hard-anodized with laser-etched inscriptions, and it's built to last. Each sample is checked and numbered as a single masterpiece.
