The Nano TorqBar is the slimmest preset torque wrench available, but don’t let its size deceive you. It is a precision-crafted, high quality tool for either the home mechanic, professional bike shop, or your own jersey pocket. Its advanced torque limit release design consistently applies precise torque values on component bolts for safety and prevents damage to expensive carbon parts. Includes 4Nm preset TorqBit and the 5 most popular tool bits (3 / 4 / 5 mm hex & T20 / T25 Torx®). Two of your favorite bits can be carried in the handle of the Nano TorqBar for immediate use and even greater portability during rides.
