Park Tool PT-ATD-1.2 Adjustable Torque Driver

With carbon fiber components and low torque specifications becoming more common on bicycle components, a torque driver is an essential tool for bike maintenance, adjustment and assembly. The ATD-1.2 is a shop-quality torque driver that limits torque applied to bolts and fasteners. The torque setting of the ATD-1.2 is adjustable by hand to either 4, 4.5, 5, 5.5, or 6 Newton meters (Nm). Once the torque limit is reached, the tool gives a loud "click" and will not turn the fastener any further, preventing over-tightening and damage to lightweight components. Includes 1/4" hex drive bits in the four most common sizes for small bicycle fasteners, which are stored in the handle when not in use.

The ATD-1.2 features all-metal internal construction for years of accurate use, with a comfortable, ergonomic molded composite body. Each tool is assembled and calibrated at the Park Tool factory in St. Paul, Minnesota.

Press

• This tool offers everything we loved about the Park Tool PTD, but with further adjustment options. Accuracy is not quite as consistent as the preset options, but certainly close enough. Its American-made build quality is superb, but that does mean it’s heavy and priced relatively high.
