I came home with a slow leak the last 3 rides in a row. So, picked up Thin Skins at the LBS and used one in the rear tire for today's ride. It worked - no slow leak. This time the tire simply blew from a large puncture. Looks like it got in just beside the Thin Skin.

The TS is much lighter than I thought - pretty much negligable. Just wondering if they actually do any good. Anyone else have experience with these?
