Slime Bike Patch Kit
Don't stick yourself with a flat!
These are considered "self-annealing" patches, because...they anneal themselves. But seriously. There's a chemical process at work here that basically guarantees that these patches will last the life of the tube. I keep a box of these on me whenever I ride, because they weigh almost nothing and they let me fix seven holes instead of the one that my spare tube allows for.
This patch kit works fine but I don't know why you would waste time using these older style kits when Slime has the Slime Skabs, which are 10 times easier to use and work just as well if not better, for almost the same price.
