I am a torque wrench believer! My bikes have a bit of carbon on them, and it scares me to think how much I would over tighten them without it.
If you have read this for a while, you might have seen my review of the amazing guistaforza torque wrench from effetto mariposa. It really is a nice tool, and when you spend that kind of coin on it, you are always sure to use it.
That wrench tops out at 16nm, which is enough for most bike parts, but bottom brackets and cranks can use more. Along with non bike uses like car stuff that I pretend I know how to do.
So for higher torque ranges I use the Park Tools TW-2 . While the guistaforza came with bits, most 3/8″ torque wrenches do not. Unfortunetly this can be pricy as you’ll need hex, torx and the usual sockets. At your average home depot or sears a set of allen head sockets will run you up to $30. And then you need to buy the torx as well. You can run to Harbour Frieght and get them for about $10 per set, but the quality is sub par.
I found the answer, over at Northern Tool they have a set of hex, phillips, blade, metric allen, imperial allen and torx on sale for $11. Yes $11, so keep an eye out to go on sale again. They are really nice, high quality and come with a case to hold them all.
Also with this adapter you can use them in the guista forza if you need to.
