Plus, providing you don’t have precision parts to install – such as Garmin’s Vector pedals – that need a specific torque for correct calibration, then most home mechanics may never need more than a couple of these.
This one, as the name suggests, is set to 6nm (newton metres), but Topeak also do a 5nm version for the same price. For the most part, 5-6nm tends to be the suggested clamping limit for carbon components, although if you use carbon assembly paste then it’s possible to install them with lower torque. (Actually, I’d suggest using carbon paste anyway, as it’s just another layer that makes sure things stay tight).
The function of one of these is really very simple. Basically, you add one of the attachments, insert into whichever bolt you want to tighten and twist – and when you reach the preset torque limit it’ll slip so you can’t tighten any more. Really simple, and very effective.
The Torque 6 comes with four supplied bits, 4, 5 and 6mm allen bits and a t25 torx bit. That should cover most things on most bikes short of the derailleur limit screws, and even if you already have a torque wrench, it simplifies the process somewhat. Plus, the opening at the bottom of the torque key is a standard size so if you already have a set of bits you can attach them too and expand its proverbial repertoire.
One other smart little function is that the supplied bits are magnetic, as is both the end of the key and the recesses in which they sit at the top. It means if you forget to take it out it wont simply drop out the bottom leaving you scrabbling around on the floor. (Not that it’s ever happened to me, you understand, that’s purely hypothetical…).
Construction-wise, Topeak have go things spot on. The top is nice and thick, and long enough to easily get a strong grip on which makes it comfortable to use. You can’t ask for much more, really.
Smart, simple and elegant, preset torque keys are a really useful tool for anyone who wants to maintain their bike at home. They’re far cheaper than a full-on torque wrench and, in all honesty, much more suited to the average home mechanic’s needs.
