i bought a cannondale quick 4 last month.
the glossy black one with white accents.
i ride anywhere between 70 - 120 miles per week.
i have no complaints about this bike.
i absolutely love it.
for only $600? well worth it!

to be fair, i believe that the trek 7.3fx (not the 7.5fx) is a closer match to the cannondale quick 4.
