Torque wrenches have become an essential bicycle tool. The increase in carbon fiber bikes and components have driven the need. While carbon fiber allows for more optimal design and provides a far higher strength to weight ratio compared to steel and aluminum, it is also more susceptible to crushing and cracking when improperly set up. Pedro's Bit Set is designed to work with our Demi and Pro Torque Wrenches offering the most common sizes required. Made from heat-treated steel for strength and long-lasting performance, this set includes a 1/4" drive adapter, 2, 2.5, 3, 4, 5, 6, and 8mm hex bits, and T25 torx bit. Backed by a Pedro's lifetime warranty.
