The chain pin pictured at the left is a small device that, normally, prevents the chain from falling off of the chain ring when the ISWE Birdy is folded. When the chain does however pop off, as happened last week when I clumsily unfolded the Birdy improperly to rush off to eDoc training, the chain pin also prevents the chain from going back on the chain ring. It does that really really well. In fact, no matter how hard I pried and prodded, it prevented me from putting the chain back on the Birdy for about five of my fifteen precious minutes. All I accomplished in that time was covering both hands with copious amounts of grimy chain grease. As I looked down at my blackened palms juxtaposed to my clean white button down shirt, I thought, "Im going to be late, I'm going to ruin this shirt, and my coworkers are going to come in and think, Barry is a total idiot!" With mere seconds to act before all three events occurred, I remembered my Doc Allen's Versatool !!!
So, please consider picking up a Doc Allen's Versatool. They are way cool, made in the USA, and pretty inexpensive, especially considering they would probably outlast the cockroaches that would survive a nuclear apocalypse... Plus, using one makes you totally feel like MacGuyver and that's way good for your self esteem.
