Effeto Mariposa Giustaforza II Pro Torque Wrench

The Effeto Mariposa GiustaForza Pro Torque Wrench is designed 100% as a bicycle torque wrench specifically for precision lightweight parts. Is features both a 6.5" compact size and heavy-duty build quality.

The 2Nm to 16Nm is the best torque range for precision bicycle applications and potentially delicate components. 2 Nm is good for small aluminum screws, 16 Nm is enough for big M6 bolts used in some seatposts (always use the manufacturer's recommended torque setting and common sense). A wider scale wouldn't allow the same .5 Nm precision.

Includes 2, 2.5, 3, 4, 5, 5L 6, 8mm Allen, T20, T25, and T30 hardened steel bits.


  • 170 grams
  • Compact 6.5" size
  • Easy to use
  • 1st recalibration is free
  • Graduated scale with 0.5 Nm increments
  • 16 bits included
  • Bits are S2 special steel, with very high (62 Hrc) surface hardness
  • Anodized aluminum
  • Steel adjustment knob and bit holder
  • Professional precision: +/-4% guaranteed for 5,000 clicks (torque applications)

Note: Always return the GF setting back to 2 Nm when not in use to ensure long-term accuracy.
