Yes, I do realize the irony of the name of this post, adding No Tubes to tubes. It never sounded that odd until I saw it written out.
Stan’s No Tubes liquid latex-based sealant is the best proactive way to avoid flat tires on any bike, including road bikes. At our Ladies Night last night, a 2 oz bottle of this liquid magic was included in each of the 100+ goody bags for those that came. Originally intended for tubeless tires, we have found this very effective in tubes.
- Make sure your presta valve has a removable core. All of the replacement tubes we sell have removable valves, but most of the bikes come with non-removable cores. Sealant can be added if you have a non-removable core although it is messy and difficult. I won’t explain how to do that today. Removable cores have flat sections that you can put a wrench on two sides, the threads are ground flat. In picture 1, this shows the flat sides.
- Remove the core from the valve using pliers, a wrench, or a valve core tools if you have one. I used a comically large adjustable wrench in the photo.
- After removing the valve core entirely, inspect that the valve stem is free from blockage.
- Add sealant to the tube. The mountain tube pictured gets 2 ounces of sealant per tube, a road tube takes 1 to 1 1/2 ounces.
- Reinstall the valve core and tighten sufficiently. Install the tube and pump up as usual. A tiny amount of sealant might leak out when you put a pump on it. Clean up any mess and it should be fine.
- Enjoy and celebrate your flat free experiences ahead! (Not pictured)
