[MENTION=90453]tjspiel[/MENTION] is right...a new Trek 520 has an MSRP of $1260, a 520 with discs is $1360, a 720 disc is just under $1900 and a 920 disc (adventure touring model) is right under $2k. You could sell both Treks and you could easily go as high as the 920 disc (of course, that is without dyno hub - but if you want a bike that can tackle anything, wow.)
