It's funny how random circumstances can shape your life.
Once, in 1995, I was building up a new mountain bike for myself, after hours at the shop. I had all of the parts I needed, already paid for, and I was really looking forward to just getting the bike done and going home.
I got all of the parts hung on the frame, and realized that it was after nine o'clock, and I was dead tired. So, I threw everything into my truck and headed home, happy that I was off work, the next day. I figured I would finish assembling the bike, in the morning, then go for the inaugural ride.
The next morning, I put the bike in my stand in the basement, hooked up the cables, and got everything adjusted. It was only when I went to install the grips that I realized I had never grabbed a new set for this bike.
I rummaged around in my spare parts, and finally came up with a pair of the same grips. The only problem was that one of the grips was black, and one was red. I installed them, and figured I would just take them off and put on a matching set at the shop.
Two months later, I realized that I had never matched up the colors on the grips. I was wrapping the bars on my road bike, at the time, so I wrapped one side in black, and one in "natural" (brown), in honor of my mountain bike.
I ran bi-colored grips for years, and thought of it as my signature. Eventually, it was more convenient to wrap both sides in the same color, or to use matching grips, and I abandoned my mismatched color scheme.
Now that I think of it, though, it might be time to get my groove back, grip-wise...
