    Display-worthy shop staple.

    Torque specs are there for a reason, especially when you’re wrenching on a $12,000 carbon fiber masterpiece. Get the build right, and the bike will ride perfectly. Get it wrong and components will break in the shop or fall off on the road. The Effetto Mariposa Giustaforza II 2-16 Pro Torque Wrench is the best tool for getting your build just right. When you’re done with the build, you can place it on the mantelpiece with your other works of fine art.

    The Effetto Mariposa Giustaforza II 2-16 Pro Torque Wrench is easier to use than it is to say. You just insert the appropriate bit and set the torque with the dial on the handle. When the correct torques has been reached, the wrench produces a loud click and allows three degrees of free movement.

    Worth it

    • Familiarity: I've put it through the wringer

    This has a strong click when it hits torque. Very easy to dial. The bits included are actually not bad. Better than some chrome bits that strip out easy. The long bits are super nice for getting into brake calipers or on rear brake caliper bolts where the frame is in a tough spot. Have really enjoyed this tool. I have not verified the accuracy but it matches very close to my other torque wrenches.

    Terrible accessories

      This torque wrench is very expensive and feels good in the hand. But the included bit holder and the various heads (bits) are the lowest quality I have ever seen -- any $20 collection is infinitely better finished and fits together better. The fit is so bad as to make the torque readings suspect. And amazingly there is no standard length 5mm hex head -- just a 4 inch (100mm) bit. In the end I had to use my Wera bit holder and bits to have any confidence that I was measuring torque to the bolt in question, and not to the slop in the Effetto parts. It is incredible that these parts come with what Effetto describes as a professional tool.

      The Ferrari of Torque wrenches

        Wow! I've used other torque wrenches in the past and never have I trusted something so much when it comes to tightening expensive parts. With torque wrenches, you really get what you pay for. The Giustarforza is a very high end and very well calibrated tool. Finally I can rest easy knowing I'm torquing to the proper specs without a doubt on the first try. This wrench has a very satisfying feel so you know you're very close and then the subtle click to stop. It includes a sweet roll up case, plastic storage box and all the bits and extensions make a great set to add to your toolbox!

        Work of art tool

        • Familiarity: I've put it through the wringer

        I had a torque wrench and bought this because it was just plain gorgeous. It turns out that it is also useful. I have the first version of this and the torque settings are spot-on. I am lucky to have a local machine shop that does high-precision work and had them check it. It came within 2%. The analog dial is also quite accurate. As a rule, and except for the crank components, I slightly under-torque most of my components like the seat post, bars, etc. I have never had anything slip.

        Gorgeous precision torque wrench

        • Familiarity: I've used it several times

        Not cheap by any means but this tool is simply gorgeous and so well suited for work on a bike. Small enough to get practically anywhere and very precise. You pay for what you get and some people will say hey this is too expensive. Fine don't buy one. Some tools are just worth it and this one spoke to me. BTW, until they get the site correct on this, I got this from CC but through Amazon. It does not come in a tin like the picture (something of a bummber) but did come in a red plastic wrap up with velcro which is probably more practical when you think about it. NOTE THOUGH THE WRENCH DID COME WITH THE BITS SO YOU DON'T HAVE TO BUY THE SEPARATE SET CONTRARY TO WHAT IS SAID ABOVE.
