The Keychain Bike Tool That You'll Always Have

People can debate forever about the best bike tool, but it's very clear — the best bike tool is the one that you have when you need it. Taking ten essential bike tools and condensing them into one handy keychain, the Ringtool will help keep you from getting stranded. Unless you lose your keys.

The Ringtool has 3-, 4-, 5-, 6-, and 8-millimeter hexheads, flat and phillips screwdrivers, a Torx key, and two spoke wrenches for two different nipple sizes. Getting torque can be a problem with such a small amount of leverage, but you can always put a stick or bar through the hole and give yourself more purchase on those rusty bolts.

And of course, it's a bottle opener as well.
