I have a pair of Bontrager Race X-Lite Pro 700x23 clincher tires, brand new in packaging. Got these for a specific event that I now can't do. If you follow the rolling resistance testing data floating around slowtwitch, you know these are some of the fastest rolling clinchers you can buy, they measure a true 23mm, and they're not superthin or flat-prone like some of the other very fast tires.

My pair is brand new in packaging, never removed or mounted on a rim. I'll take $110 shipped in the US for the pair.
