Replacing tube from sheldon brown: Tube Replacement
To replace the entire tube, open the tire on one side of the stem, the side that seems to be easier to re-sew after the repair. Open about eight to ten cm the usual way, so that the old tube can be pulled out by the stem. Cut the tube and attach a strong cord to the loose end of the tube to be pulled through the casing by the old tube as you pull it out. Cut the "new" latex tube about 8-10 cm away from the stem, tie the cord onto the loose end and pull it gently into the casing. Dumping some talc into the casing and putting talc onto the tube help get the tube into place. With the tube in place, pull enough of it out by stretching it, to splice the ends together. Splicing the Tube This procedure works only with latex tubes. Overlap the tube ends so the free end goes about one cm inside the end with the stem. With the tube overlapped, use a toothpick to wipe Pastali rim cement into the interface. The reason this MUST be done in place is that the solvent will curl the rubber into an unmanageable mess if you try this in free space. Carefully glue the entire circumference and press the joint together by pressing the tube flat in opposing directions. Wait a minute and then gently inflate to check the results. More glue can be inserted if necessary if you do not wait too long. Bill S -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
