Today i rode 11.6 miles before my clutch or pawns in my cassette blown out leaving me stranded. I walked 2 miles to the nearest intersection and called a cab to transport me to my parents house where i switched out my road bike for my carbon one. I sold the broken bike because it was causing too many problems. Then i rode 31.5 miles with the carbon road bike from palo alto to redwood city and back, and took the train back to san jose.
