also information on my usage:
my commute on the bike is about 6 miles (one way) and depending on route could have some small rolling hills but mostly flat, on good pavement (not gravel, or pot hole ridden).

I can usually go as fast as 21 mph, but my avg speed is usually around 14 mph...

on the rim is a label "x202" with the number 6061-t9 and it does have taiwan on the label...
