I have the 7.5 FX and use it for my daily commute. It came with 700x28 tires, contrary to the 32C called out on the Trek website. My commute takes me over semi-rough pavement. The 28C wheels are more than adequate for street riding in my opinion. So far the wheels have held up to daily use even with a loaded trunk rack and my 230lb weight. The hard case tires have held up with no flats so far. The bike was less that $700. I purchased this bike because I like the components. I was concerned about the wheels, and I will replace them if they don't hold up. I was told by the sales person that these wheels were just as durable as wheels with a higher spoke count because the spokes have a higher strength and the rims are stronger to compensate. He may or may not know what he is talking about, but that wasn't my primary concern.
