You’ll find both glue and glueless patch kits. Which one to use is a topic all by itself but I believe most people use the glue patch kits because of their durability. I’m not sure it really matters which kind you have as long as you have one. They take up very little room in your seat bag and you will need it at some point.

Spare Tube. Some of you may ask, saddle bag for road bike“Why carry a spare tube when I have a patch kit?” After hearing advice from other riders, and my experience back on Ride 21 and 1/3 I carry a spare tube now. I carry the spare tube because, if I do get a flat, it’s much easier to just put the new tube in rather than try and patch the old one. Especially if it’s dark outside. I carry the patch kit in the event my spare tube flats.hydration hiking backpack I also carry the spare tube so I can give it to another cyclist if they need it. I did this back on Ride 28. If you give your spare tube away you’ll need the patch kit if you get a flat.
