Review on Bison Designs Keychain Cyclist 12 Piece: Compact and Convenient Cycling Accessories at Your Fingertips by Leah Gomez

This is a great little key ring/belt clip that has a lot more uses than most. I've used this to adjust my bike in a pinch and it definitely works. Hex wrench heads can be a little tricky to use, especially two on opposite sides of the tire, but they work. A bottle opener is always useful. The hoop hole is perfect for opening a paint can. If you don't see the point in bike tools, check out Bison Design's dedicated clips. For the price you really can't get any better.
