The picture shows two shields, but it doesn't really matter. Perhaps they are only shown in front and behind. In fact, two shields came with one order. Ordered two, looked for two, got four. It is in order. The magic number of protectors needed is usually three. I have MP-0357 wheel protectors (with attached rope). They are somewhat bulky and often a bit difficult to work with, especially with cast wheels. They are noticeably thinner, although NOT as thin as I had hoped. They are 5 inches wide. Big! I have four bikes. I changed several tires. They will do their job perfectly. Make them nest inside each other and that will reduce the backpack space a bit.
