As a child I had solid rubber inner tubes in my bike. They were a pain to get on but after I never had a flat again!
Now I've recently started biking again and have had two flats in two days, each resulting in a three-mile walk back home. I've been searching for solid rubber tubes for a few hours now, but have only found them at wal*mart, and they don't have the correct size? (700x38c)
Why have they disappeared? I thought they were a fantastic product . . .
