I have a Trek FX 7.6. I've got it tuned to my liking except for the tires. I had the LBS swap the 28s for 32mm. My plan is to ride exclusively on paved surfaces. Unfortunately, like most things in life stuff happens. The roads around here have serious ruts in places and the 'paved' bike paths frequently change to crushed granite. This substance is unstable and the edges of the stones are sharp as razors. I've been out on the paths three days now and continue to be surprised by it. How wide a tire have some of you FX owners put on your bikes? Any special tire/tread? The ones they put on my bike are essentially bald so the front wheel does a dance once it gets on the gravel or dirt.
