Park Tool TW-5 Torque Wrench

Product Information

In fact, using many torque wrenches 'the wrong way' can damage their mechanism and stop them from accurately gauging the level or torque. If the tool you've got does not do reverse thread, don't try and use it for reverse thread (or for loosening bolts). Measured torque not typically used. Common industry practice is resistance at lever half way through swing from open to fully closed. For more see Tire and Tube Removal and Installation. Make sure you take care of your torque wrench and whenever you’re not using it, reset it to zero or its minimum setting. The Lifeline Essential Torque Wrench set is a simple, yet effective, and very tactile torque tool that will do most (small) tasks that the average home bicycle mechanic is likely to take on.

The other advantage with using a torque is you don’t have to guess how tight things should be. The old school way is hand tight and then another quarter turn but what does that actually mean? If a seat clam bolt has a torque setting of 5nm and you use a 5nm pre-set torque wrench, you’re never going to over or under tighten it, and also you won’t have to touch it again. It’s all too common for cycling-specific torque wrenches to be made to a price point, typically using plastic internals as a result. The ATD clearly ignores its existing competitors and offers incredibly durable and positive feeling metal internals. Finance is subject to application, financial circumstances and borrowing history.

Not using a torque wrench puts you at risk of a bolt snapping, or indeed a delicate, carbon component giving way or being crushed under too much pressure. In the case of a handlebar, this can be dangerous; and if it’s proven that you’d overtightened a bolt and caused the fracture then your chances of a warranty claim could be voided.Threaded fasteners, such as nuts and bolts, are used to hold many components to the bike. As a fastener is tightened, the fastener actually flexes and stretches, much like a rubber band. This stretching is not permanent, but it gives the joint force to hold together, called “preload,” or tension. Each fastener is designed for a certain range of tension. Too much tightening will deform the threads or the parts. Too little preload will mean the fastener will loosen with use. This can damage components, such as a crank ridden with a loose mounting bolt. Loose bolts and nuts are also generally the source of various creaking on the bike. The TW-5.2 has a range of 2–14 Nm (18–124 inch-pounds). The TW-6.2 has a range of 10–60 Nm (88–530 inch-pounds). Despite its appearance and cost, the handle parts feel like they don’t quite fit perfectly together with some wobble rather than an assured fit A torque limiter uses a built-in clutch system designed to release when the resistance at the fastener exceeds the resistance of the clutch. Generally, torque limiters are used on lower-torque fasteners such as stems, bars, rotor bolts, cable pinch bolts, etc. There's an array of different alternative bolt sizes used in headsets and stems, particularly proprietary designs, while things like chainset bolts tend to be a different size again. Anything else I should look out for?

NOTE: Torque wrenches are measuring instruments and are not intended for use as a general-purpose ratcheting driver. Do not exceed 14 Nm when using the TW-5.2. Repair & Service The TW-1.2 has a range of 0–14 Nm (0–140 inch-pounds). The TW-2.2 has a range of 0–60 Nm (0–50 foot-pounds). The ‘Deluxe’ tool wrap and bits are great quality and it even includes a free calibration service (in Italy…). All wrapped up, it’s compact and doesn’t waste space in the toolbox.It comes in a foam-lined hard plastic case, something we found tough to actually get the tool out of. However, it does keep it safe and all the bits together.
