Effetto Mariposa
Giustaforza II 10-60 Pro Torque Wrench

5 out of 5 stars
1 Review



Giustaforza II 10-60 Pro Torque Wrench

Originally built in Italy, the Effetto Mariposa Giustaforza II 10-60 Pro Torque Wrench lives up to high expectations. The Giustaforza II uses no batteries or electronics—the first to break in any tool. It's unlocked by a knob located on the wrench end; once unlocked, set the desired torque value, push the knob back in to lock in place and away you go. When you reach the desired torque, the Guistaforza II delivers a confident 'CLICK' and provides three degrees of free movement in the handle. Set with a +/-4% tolerance, the Guistaforza II's precision is top-notch, because when you're installing that ceramic bottom bracket on your expensive carbon machine the last thing you want is an inaccurate reading.


  • Pro torque wrench with capacity from 10 to 60Nm
  • Square 3/8-inch reversible ratcheting head for convenience in use
  • +/-4% tolerance is guaranteed for 5000 cycles (5000 'CLICKS')
  • Stainless steel body for years of reliable use
  • Torque range is ideal for the highest torque specs found on a bicycle
  • Laser-etched inscriptions add aesthetic appeal
  • Item #EFF0008

Giustaforza II 10-60 Pro Torque Wrench

I've used it once or twice and have initial impressions

I received this torque wrench a couple days ago so this review is not on long term use. I went wright to work re-torquing everything on my Santa Cruz CC Nomad X01 eagle in the 10 to 60 nm range. I literally loosened and torqued everything back down. As far as accuracy I can only say it feels correct when comparing the feel of when it clicks to my older torque wrench and I'm sure its calibrated before its sent out so I am very happy with its performance. I recommend this to others if they are looking for a solid high end torque wrench. The only thing is the sight glass where you read the torque value is a bit small but not to small so I need to wear my glasses to dial it in. Anyway... Competitive Cyclists Back Country are an excellent group of people to deal with and I will continue to make there website the first I go to when looking for gear.
