Are thorn-resistant tubes available in these wider 700 tires? Brand? Source? I like Performance's thorn resistant tubes for commuting, but they are available in only one size, 700x23-26. I want to put some wider tires on one set of wheels for some light off roading with some of my riding buddies. Any suggestions would be appreciated.

In answer to my own question, Quality Bicycle Products, the big distributor most LBSs by from, has started labelling its own brand of thorn resistant tubes in at least two sizes - 700x28-32 and 700x35-43. Performance offers a single smaller size at 700x23-26. I have been using the Performance tubes for a couple of years, and like them. I just got some of the QBP 28-32s though I haven't installed them yet. The 35-43 are on backorder.

You might consider using "Slime" tubes rather than thorn-proof tubes. They are available in a variety of wider 700c sizes and are lighter, easier to mount, and just as, if not more, reliable than thorn-proof tubes.
