Tear-aid patches come in two varieties which can work wonders for touring cyclists. They are airtight, watertight, won’t fall off over time, have immediate bonding with the surface, and can be cut with a simple leather-man scissor tool.
According to the Tear-Aid website:
Type A patched adhere to canvas, rubber, sunbrella, plastic, nylon, fiberglass, aluminum, stainless steel, polyethylene, polypropylene, polyurethane, Gor-Tex, deacon, polyester, and hypalon.
Type B patches can stick to vinyl and vinyl (PVC) coated products. These can also be applied underwater.
I used Tear-Aid Type A patches hundreds of times throughout my cycling… commuting, racing, and touring. They have worked wonders and have easily replaced patch kits; I used them for 4000 miles during a summer 2011 tour. I also would throw some on my tires when the Kevlar began to peek through to extend its life; they have saved me when I was quite far from the nearest bike shop. I have used them successfully on rain gear, tent, sleeping bag, my Gor-Tex gear, my Nashbar waterproof panniers, Bob trailer bag, and other clothing which developed holes in them.
I haven’t used Type B patches, but have heard from several other cyclists they will work on PVC coated fabrics; Type A will not. This will help with most waterproof panniers (with the exception of Ortieb).
The only gear I have found these patches not to be a viable option is when trying to extend the life out of some lycra shorts, and my cycling jerseys. It will stick to the material, but not for an extended period.
The only complaint I have with these patches is due to my negligence of care for them; these patches must be kept dry. I tend to keep 3 ziplock bags with a couple of them in various places in my bags. If the patch gets wet it becomes useless, because they begin to stick to the wax paper you peel them off of.
I don’t really consider this one a bad thing, but some people might. The patches are extremely adhesive; if you were to accidentally stick it on the wrong spot it’s nearly impossible to take off again – practice is recommended.
I would highly recommend these patches. If you don’t want to make them your only patch during a cycling trip – okay – I would still recommend putting a few in your emergency kit.
