messing around with the bars on my bike last night, forgot to tighten the stem the rest of the way..
bombing down a hill (bike with gears today), pull on the brakes, bars rotate forward, HOLY ****ING **** i screamed as i cruised thru a 4 way stop as drivers shook their fist at me..

luckily i got to pull over and and tighten the living **** outta that stem
