About "glueless" patches: Some cyclists prefer to carry "glueless" patches for on-the-trail repairs. These come without a tube of glue, so applying it and waiting for it to dry are unnecessary. Instead, the patches carry a strong adhesive. To fix a puncture, buff the tube lightly with the sandpaper included in the kit, brush off the dust, peel off its backing and affix the patch. Careful! Don't trap any air beneath it.
