well i found a crack in my left crank arm awhile ago so i took it up to bikeworks to get it checked out...the guy said its just a scratch in the weld...so today i got a pic of the rail hop from my other blog entry and i did it perfectly but the picture was timed wrong so i go to do it again and while im gettin speed,my left crank arm snapped right at the crack, and more than just where the crank was.just a scratch huh?im so pissed but at least my crank didnt break during the rail hop
