These patches tend to be smaller diameter than many of the name brand options which is great for road bike tubes making the patching process easier. Unlike the alternatives, these are about the width as a flat tube eliminating the need to wrap the patch around the tire. Prep, glue and stick down the patch. Haven't had any issues since I started using these.
I was tired of always having to be careful wrapping the edges of other larger patches around small road tubes. These patches are the perfect size. Stocked up on a bunch of them for a great price.
Like most patches, the plastic top coating can be a bit of a hassle to peel off, but these are solid overall patches. I use these for all of our bicycles mountain, commuter, and road.
It's a tire patch kit which supplies you with six patches and plenty of vulcanizing goo. The patches are all the same size in this kit, Park Tool tire patch kits supply a variety of patches, but less goo. For normal road riding, these are probably just fine. I prefer Park for off-road riding. Only thing to worry about (and this applies to all patch kits), the goo can dry out leaving you stranded.
