Ideal Torque Range- 2-16 Nm* is ideal for precision bicycle applications.

Lightweight & Strong- The light aluminum body keeps the weight down to less than half the weight of heavy industrial wrenches often used for bicycles.  The adjustment knob and bit-holder are made of steel for daily use.

Professional Precision- Torque tolerance is +-4%, according to UNI EN ISO 6789:2004 norm.

Calibration Service- After 5000 cycles (5000 'clicks'), the GF wrench should be re-calibrated. After every calibration, the tolerance of +/-4% over nominal values is guaranteed.

A State-of-the-Art Tool- Made in Italy, functional, linear in design, and precise in every detail. The tool is hard-anodized with laser-etched inscriptions, and it's built to last. Each sample is checked and numbered as a single masterpiece.

Easy and Safe to Carry- The wrench, parts, accessories and instructions  are packaged into a convenient and portable sleeve that rolls up and secures with a velcro strap.
