Picture of How to fix a detached valve from the inner tube
For the begining, I am sory for my bad english. So, let's start the instructable.

One day I ride my  mountain bike in the middle of nowhere  where I made a flat tire. No problem I said, I have my pump, patches and glue, so I started fixing. When I opened the tire I saw that the valve was broken. Civilization had to be done about 25-30 km, the phone signal was missing so after a swearing series I started looking for solutions. After 15 minutes of thinking, bike and nature study for solutions, I foud to the following solution:

I took off two washers from the brake, I put glue on the end of the valve, put one washer on the valve and I stuffed the valve and the washer in the inner tube. I spread glue solution on the outside of the tube, I put the other washer over the tube, then I screwed the nut that holds the valve normally. I mounted the tube and the tire on the wheel. If you like this instructable, please vote! Now, let's see all steps.

Step 1:

AWESOME! And I loved "after my swearing series" because I too have those:-) I am currently working on a huge tractor inner-tube so this may work for me. Thanks

Great instructable! Look on youtube for the user: Leendert Pot entitled "solution". They show how to repair a tire with just a piece of string!

Interesting. I drilled all my rims for Shraeder valves. I can use Presta or Shraeder tubes.

For race bikes I don't find Shraeder valve tubes. Of course, Shrader valves are better, but and I don't want to change the valves for every new race tube.
If the rims are drilled for Shrader (slightly larger), Presta tubes can work fine in them, especially with rubber grommets, or small spacers made from bic pen tubes. It opens the range of tubes that can be used, especially in a breakdown situation.

I agree. But not for all kind of bikes you can find Shrader valve tubes, so it's useless to drill the rims.
Interesting. What size rims and tires are you using? If it's 700c, economical schrader replacements are easily available by nominal 27"x1 tubes, with long threaded valves for aero rims, and standard valves for box rims.

maybe you screw the nut too tight and the washer slipped.

Awesome job! And your english was understandable...so thank you very much for contributing! I hadn't of thought of this, but had this happen to me! (Un)Fortunately, there's a cellular signal everywhere I ride. Great for tricky valve fixes...bad for getting away!
