Park Tool suggests that having a Ratcheting Torque Wrench is a must when we're working in the shop. It's a high-quality, ratcheting torque wrench that applies the appropriate amount of torque to a component's threaded fastener, and it's designed for higher torque settings. This is useful for bottom bracket, cassette lockring, and other areas of repair and installation. It comes with its own protective case, and we think it's a must for every cyclist. It reads and registers both left and right-hand threading, and a dial-adjust system allows our desired torque setting to be preset. For a lower torque setting, Park Tool recommends the TW-5. 2.
