Shimano PRO Torque Wrench

If you've ever tried to tighten a seat post binder bold when your saddle was slipping down, or you've installed a water bottle cage, you've probably stripped something by over tightening. A torque wrench takes the guesswork out of how many more twists until your bolt is tight by limiting the pressure you exert by turning—a little bit like a gas cap. The best selling tool in Shimano's North American line, Shimano's Pro Torque Wrench makes everyday maintenance as well as bigger repairs stress free. $140,
