Pro Torque Wrench
Every bolt on a bicycle needs to be tight. Knowing you snugged up your brand new $300 handlebar within 0.2nm of spec will just give you that much more confidence in your handy work. Pro, Shimano’s component company, makes some pretty great tools and this one is no exception. The Torque Wrench, which retails for $150, is accurate from 0.4 to 15nm and includes six bits. I travel with mine anytime I fly with my bike, typically just bringing the M4, M5, and the T25 if I’m flying with a disc bike. Always remove your brake rotors when you pack your bike. Always.
