With regard to "Glueless patches" :
I flatted the other day, had a spare tube and some glueless patches. I had a little time, so I decided to try the glueless patch. It was a warm day and the patch seemed to bond nicely to the tube. I completed my ride (about 20 mi and made it home). Once home I showered, eat, blah, blah, blah, went outside about 2 hr. after I got home and tire was completly flat.
Moral of the story is it got me home (good)! It was super easy to fix on the road.
Later in the day, I peeled the glueless patch off and put a "glued" patch on.
My new packing protocol is to add 4-5 glueless patches to my seatbags. I figure worse case scenario with flatting 3 tubes (1 on bike and 2 spares), I will at least be able to get home.
