This Torque Wrench from Keith Bontrager and his team could quite possibly be the handiest little bike tool I've ever owned.
A walk around the Allen bolts on your bike is a snip with this little beauty. Preloaded to 5Nm and with a comfy grip Keeps is Simple, ie. a no-brainer.
If you like to 'tinker' and you care about your bike, especially the carbon bits, it's hard to go past one of these; but keep it handy, you'll want to use it.
