One of the most common [url=http://www.icarbonsports.com/products/wheels-rims/road-wheels/]bicycle carbon wheels[/url] bicycle repairs. I personally recommend replacing a tube when you get a leak, but that is not always possible. If done properly, a patch will work just fine. Here¡¯s how it¡¯s done.
Required Tools
inspect the outer surface of the tire to make sure there are no sharp objects like a thumb-tack or thorn stuck in the tread.
Remove Tire
Remove the valve cap and fully deflate [url=http://www.icarbonsports.com/products/wheels-rims/]carbon bicycle wheel[/url]the tube by depressing the valve stem with the hooked end of your tire lever. There are two main types of valve stems, a schrader valve and a presta valve. This tutorial is based on a schrader valve, but I will be covering the different valve types in another tutorial.
Now it¡¯s time to remove your tire, one side at a time. Choose a section of tire that is away from the valve and hook one of the tire levers under the bead, directly in line with one of your spokes. Pry one side of the tire bead over the edge of the rim, and then hook the end of the tire lever to the nearest spoke. Insert another tire lever two spokes away from the first, and a third another two spokes away. Now the middle lever should fall out, and you can continue the process. When the tire is loose enough you can just run a tire lever around the rest of the rim to pull the whole side over.
After you have removed one side of the tire, the ICAbike01 other side should come off very easily.
Now remove the tube from the tire, and try [url=http://www.icarbonsports.com/products/carbon-bike-frame-fork/]carbon fiber bicycle frame[/url]to keep track of where it was positioned in relation to the tire. Inflate the tube to approximately twice its original size. This will expand the hole making it easier to find.
Listen carefully to the entire circumference of the tube; you should hear a hissing sound that will indicate where the leak is. As a last resort you can submerge the tube in water and watch for bubbles, but you¡¯ll want to avoid doing this as you¡¯ll need the tube to be completely dry in order for the patch glue to work.
Once you¡¯ve found the leak, take note of [url=http://www.icarbonsports.com/]zipp 404[/url]whether it is on the inner or outer side of the tube.
If the hole was on the outer side of the tube, inspect the inner surface of the tire in that spot to make sure the object that caused the puncture is not still stuck in the tire. Double check the entire inner side of the tire by running your fingers along the entire surface, feeling for obstacles along the way. |
