From 700x32c?? The tires are pretty nice on the Trek 7.3, Hardcase Satellite s. But I notice they make Racelite's in 700x28 and they are a little lighter, possibly less rolling resistance. How much would i gain in going a bit slimmer? is it worth it. Or should i just burn these out first?

I assume the wheel could at least take a tire down to this size. Again not sure, any input would be appreciated.
