I sell a 2008 Treck 7.5 FX with 20" frame in almost new condition. Upgraded with carbon iroman aerobars, ergonomics grips, Trek lights and seat bag with a spear tube and repair kit. This year's model is almost identical and has a MSRP of $919.19 +tax
I would sell mine for $550 OBO with all the upgrades.  If you want to try it give me a call -Carlos
