Also keep in mind that the size (length/torque range) you use should be appropriate for what you are working on. For example, don't use the torque wrench you use to tighten a bottom bracket, or pedal, to tighten the bolts on a carbon stem. Keep in mind, that when you use a torgue wrench for carbon parts, you want to get it tight enough, but not so tight you damage the item. A smaller, more precise wrench is needed -- as well as the torque specification. For bottom brackets, pedals, cogs, etc., you're more interested in getting it tight enough. I prefer the beam type since you're able to monitor the amount of torque you currently have, as it comes up to the required torque. In additon to the actual torque, you should note if the item should be lubricated or not, before being tightened.
