The Park Tool bicycle repair kit replaces the old troublesome patch of bicycle tubes perfectly. No fret about dried glue and stubborn patches. A hole in the inner tube is repaired in no time. The most complex it remains zoom only on the hose to come. Then patching it, press and wait a few seconds - ready. I have never been so quickly mended a bicycle inner tube. Those things are also true for small holes in Pool Plan and even the rubber sleeve of our washing machine did I get so already tight as a small hole was there. The small patch I can in any case highly recommend.
