2008 carbon Trek Madone 4.5, WSD. Excellent condition. Bought it in 08 when I started riding. Replaced it with a compact crank in 2010 and it hasn't been ridden since then. Excellent condition. Never crashed, well-maintained. I'm attaching a recent photo and a link to a spec sheet.
Madelyn, did you sell this yet? Did you try size 50 before buying size 47? My measurements are: seat tube range c-c 50.7-51.2 cm; top tube length 48.4 to 48.8 cm. Height 5'3". Do these measurements sound like yours?
