    Sloppy shifting

    Chain slap

    Chipping the chainstay from chain slap...both top and bottom

    Chain suck

    Frame chewage from chain suck

    And, finally, the other bicycles will make fun of your saggy bicycle which will lead to personality problems.

    The biggest problems would be dropping your chain and having it slap and bounce noisily when you go over bumps. Also the shifting will suffer.

    Usually you can fix it by shortening the chain by a link or two. But if the derailer springs are not taking up the slack, the problem may persist. In that case cleaning and lubing the derailer pivots often helps...

    Any chain tool will do. Though if you use one a lot you'll appreciate the comfort and chain-holding ability of the fancier models. For example, a cheap one would be http://www.nashbar.com/profile_morei...ku=6742&brand=, and a fancy one would be http://www.nashbar.com/profile.cfm?c...eid=&pagename=

    By far the coolest is the Topeak Droid! It's not a great chaintool but it's cool! Even comes in it's own space pod.

    Clearly, if your chain tool is not a conversation piece, then it's not fully functional. That thing looks like it would be hard to hold on to while pressing a pin in. I think I'll pass.

    On the other hand, the ears *are* quite adorable
