The other day, while riding to scout for spots in central Brooklyn, my drivetrain felt funny. I looked down and holy shit, my crank arms were coming off the spindle! I got off my bike and examined to find one of the crank bolts had fallen off. Luckily, I made it home ok but today I had to ride all over the city looking for a replacement.
Knowing this, I remembered something I saw on the Bicycle Revolutions blog and quickly improvised.
You gotta do what you gotta do.
