I have been running Bontrager tubes because my closer LBS is a Trek dealer and that's what they stock. I have had maybe one flat in the 3,000 miles I've been using them but I flatted both tubes in my new CAAD9 within two weeks on the same roads and killed a Specialized tube about every month. This is with the Vittoria tires that come on the cheaper CAAD9 bikes.

With the Gator Hardshells, I had no flats but I only got a few hundred out of them before I crashed and trashed the rear.
