Product Information

The Pro Bike Tool set is 'calibration tested for accuracy to ISO 6789:2003'. That means that before it leaves the factory, it gets tested and you get a little sheet with your torque wrench's performance. This one I have here was no more than 0.3Nm out on the three set torque tests. Over time, you might want to get this recalibrated, especially if you're using it a lot and needing some low torque settings. Nearly every bolt or fastener on a bike will have a torque rating specified by the manufacturer. Torque is the measurement of rotational force that is applied to an object. When we tighten down a bolt we stretch the threads creating friction, which prevents the bolt from coming undone. Too loose and the bolt or screw may work free, but too tight and we may damage the bolt or whatever it's attached to. For the same reason, you also want to be sure to release the tension on the wrench before storing it. Leaving the wrench spring in tension during storage will cause it to move out of calibration over time. It only takes a moment to set the wrench to the lowest setting before storing it and it will make sure you get the most precision out of an expensive tool.

Torque wrenches allow you to measure and limit the amount of force applied to a fixing. Every nut and bolt in your car will have a torque value. It’s particularly important that you have a torque wrench to hand if you’re working on the engine, gearbox or any crucial components in the drivetrain or suspension system. Torque wrenches are extremely sensitive pieces of equipment, and as such you need to store them properly to keep the calibration intact. Most torque wrenches come with a case, and we highly recommend storing them in this case whenever you aren’t using them.

Features

Even better, since it’s a 3/8” torque wrench you don’t have to spend nearly as much compared to some of the other options on our list. But even for a typical 3/8” drive torque wrench this one by EPAuto is available for a great price, and that’s a big part of the reason it’s our top 3/8” drive option. The only other torque wrench I have is Park Tool's ATD-1, and testing them together showed that they agreed with what torque each bolt was at. Despite the quality of that piece, that's not where your money goes. Instead of those pieces, what you are investing your money in is three torque limiters. They aren't adjustable but they do match up with the three most common specs you'll find on saddles, seat posts, and stems. If I'm being honest, I have rarely used these with the included handle. The handle doesn't have storage for all three and, given how small they are, I'd rather not choose only a single option. It’s not that we think the extension will affect the final torque spec, it’s just that all it takes is for you to get a little off-center to get an errant reading. If you use it properly there shouldn’t be a problem though.

Bits included: 2, 2.5, 3, 4 (long), 5 (long) & 6mm hex, Torx 10, 15, 20, 25 (long) & 30, Phillips #2, 100mm extension Take a look at all the jobs you need a torque wrench for and all the recommended torque specs, and then match those numbers up with the torque wrench you’re looking at. If you need a wide range of torque specs, there’s a good chance a single torque wrench won’t be able to handle it all. When it comes to torque wrenches, few options make more sense than a sturdy ½” drive option. That’s because ½” drive torque wrenches come with tons of adjustability, making them outstanding choices for both low and high torque specs.

It works like a beam-type torque wrench and so you stop tightening once the needle hits the desired number. First is the maximum torque value. At 80 ft/lbs it’s high enough for most DIY jobs, but there’s certainly a chance you’ll come across a job calling for higher torque specs. Second, it’s not the most durable option.
