Make Sure Your Mini-Tool Has What You Need - When selecting your all-in-one mini tool, test it on your bike. Bicycles and components vary and not all tools work well on all bikes. Check to see if yours can access the brake and derailleur adjustments; if the chain tool looks reliable; if the all-in-one includes the correct tools for your bike. Keep in mind that chain tools are great ride savers should your or a friend's links fail, but some tools don't include them.
