More often than not they seem to work. I have had a few give out over time or need to place a second over the edge of the first where it didnt seem to seal.
The small size cant be beat. They fit anywhere which is really nice when I can carry next to nothing on my bike.
Had been dealing with the typical patch/glue method and experiencing a hit or miss as far as effectiveness until a fellow cyclist recommended this Park Tool GP-2 Glueless Super Patch. Again, have no regrets as these are easy to use, no mess, no fuss, and sealed up a hole without difficulty. Would certainly recommended these as they are easy to put in the bike sack to have in a pinch.
For most of us flats are an inevitable part of cycling and we only carry one spare tube. There have been a few occasions where I have needed this product and it did get me home. Not hard to use if you take your time and find the correct spot to apply the patch. Remember to carefully inspect the tire internally and externally or you start all over again very shortly. Make sure to use the sandpaper that is included so the patch will adhere better. All of this takes patience and time . Hopefully along with this kit you brought both!
I haven't used glue patches in years. These work really well. I clean the tube and scruff it slightly w sandpaper given and place one side the smear it out well from the center to edges.. racing on a 6 mo old patch today
Punctures happen for those of us who still use tires with tubes. These patches work. They don't come undone after a few miles or a few days etc.. And, no more tubes of glue that don't have any glue in them! Bonus.
I keep these in my saddle bag for use in the rare instance I experience more than 1 flat on a ride (I carry 1 spare tube, plus these instant patches). Provides great peace of mind knowing I am self sufficient and can always get home.
I loved these patches till last week when for no apparent reason and no warning, one just let go over night. I came out to go to work and discovered I was going to be late. Again, the tire was perfect pressure coming home the evening before, I had no indication of failure. Mind you it held fine for a year or more, but I hate this kind of surprise. Back to patch and glue for me, can't be late to work.
I still prefer the old school patches. These seem to leak after some time. Been using glue patches for years. Ttryed these because of the positive reviews. They work ok. But stick with the old patch.
After trying four times in 100 degree heat to patch a buddy's tire with traditional patches, I decided never again. After switching to these my time off the bike repairing a flat has dropped, and my time in the saddle increased. What more could you ask for?
I always carry two extra tubes AND carry the Super Patch just in case. I know, call me paranoid but better safe than sorry. On a recent ride, this patch saved the day for a newbie rider who was stranded on the road with a flat and no tube. She'd have been riding for 6 months without a spare tube and of course her luck finally ran out. Just be sure to keep the area to be patched clean and scuff it up good and carefully apply the patch smoothly without any folds and burnish it down and it's good to go.
Had to use one of these on a ride not too long ago and it got me home great. Usually I'd swap out the tube for a new one, but this time I forgot and surprised to see this patch lasted all the months of daily use. Furthermore, I find the kits with a tube of glue pretty useless after the first repair because the little glue tube tends to harden up too easily. This is a simple peel and stick method!
