Heh, I was going to mount it on the seat rail, but thought that the under top-tube mount would capture cooler video, I really like how it turned out. Can't wait for nice weather, upper 30's gusting to 50mpg and downpour is where I draw the line... Have bunch of ideas for some more little time-lapse videos. Want to get some offroad footage on the cx bike and some sailing (racing) out on Lake Superior.
