The Birzman Torque Driver is helpful addition to your portable tool kit, as it helps you tighten bicycle components to the correct torque value on-the-go, preventing stress risers and other unwanted damage to things like carbon handlebars and carbon seatposts. The driver is preset to 5Nm, and includes four bits to cover most common bolt heads. The compact size and ergonomic handle make it quick and easy to use, and thus ideal for situations when you can't carry a full size torque wrench.
