Thanks guys for all the help! I decided to get a Trek 7.3FX Disc.
Just for comparison, I had the bike shop weigh both the 7.3FX Disc and the 7.3FX (non Disc) and the 7.3 FX Disc came out to 28.5 lbs while the 7.3FX (non Disc) came out to just shy of 27 lbs. This is with size 17.5. The disc was only $50 more so I went with it (had a special during Memorial Day weekend). The Specialized Sirrus Sport was very nice but after the Trek discount, it was $150+ more.
My question is getting the front disc to align perfect inside the brakes. It seems the brakes would touch the disc slightly (a certain section) when it's rotating free. I tried to adjust the wheel before locking the quick release but the best I can adjust is when the pad is touching the disc very slightly. Anyway to adjust it perfectly so the pads aren't touching the disc when rotating freely?
TIA!
