Me and my dad left about 12:00 noon and went 6 miles then my computer fell out, so we put it back in and it had to reset (which I probably put the wrong code in) so we went about half a mile more and then the front wheel of my dads bike started wobbling. We tightened it a little (with our own hands) and then we switched bikes and turned around and I did really good on the fixie. About 3 miles through on the way back the seat gave away and just was REALLY loose. Its not a big difference when I was down on the aerobar though. Well, we had a good time anyway.
