The way components are designed these day a torque wrench is useful for alloy and carbon parts. This tool works good for stems, bars, and seat post clamps that have low torque values. It comes with the most common hex bit sizes but can use any size hex that has a standard bit interface. The magnetic retention keep the hex bits from falling out. The only thing that would make it better is to have an adjustable torque setting but then it would cost much more. Carbon friction paste is a useful complement to this tool. A tool like this should be in every serious bike tool box.
