Link to the new 520: http://www.trekbikes.com/us/en/bikes...uring/520/520/ MSRP $1500(+sales tax in CA=$1620+-). It looks like a nice bike, but comparing it to the 620 is not really comparing "apples to apples"(as in $700 worth of apples). This is all academic to me as I'm too tall to ride anything but a custom frame.
