I used TorqKeys wrenching on carbon fibre bikes many years ago. They come with a preset torque. I got an 8 Nm one in Feb, when visiting the US, from a company called Prestacycle. Use it for final tightening of Armstrong foil gear (it clicks when hits the preset torque - it is pretty intuitive to use). I remember reading that bike mechs rarely got torque anywhere near spec. By feel they were all over the place in tests.

Got an email today that Prestacycle is having a Memorial Day sale, which made me think to post about this tool. I got this https://www.prestacycle.com/product/pre ... bits-tool/ and a few of these https://www.prestacycle.com/product/pre ... -hex-bits/ (in Torx T30). Probably easier to ship to the US but I think they ship to Canada (might cost more than the tool).

Those look interesting. I've been looking for something like this, but was looking for something that doesn't rust.

Better keep them in a bag of penetrating oil.
