I ran into the back of a parked car going about 12 miles per hour. Luckily I survive more or less intact. My bike (C-dale Synapse) appeared unharmed. Two months and 1200 miles later I noticed dimples about the size of a pinky finger on the bottom side of both the top post and the down post, about two inches from the front connections. The rest of the frame appears to be unharmed.
Question: How risky is it to continue to ride my bike? Am I tempting fate?
