How to fix a flat.

that is...

“How to replace the inner tube”.

In this day and age, most people simply replace the inner tube.

me...I often patch tubes.

this vid is about just simply replacing the tube.

quick and easy

some pointers.

Tools:

1. Pump

2. Tire levers (hopefully not)

3. Patch kit (hopefully we are just changing the tube)

How to:

1. Shift gears into “Little/Little”. Little cog, little chainring

2. Open brake.

a. Campy, push brake stop pin to “Open” position in brake/shifter lever

b. Shimano, rotate brake stop lever (on the caliper) to the open position.

3. Open quick release (QR)

4. Tap rear wheel out of rear dropouts.

5. Remove valve stem cap/valve stem nut.

6. Open presta valve (if applicable)

7. let out any remaining air.

8. Face cogset away from you

9. Place wheel on the ground in front of you, with cogset facing away, valve stem at the bottom of the wheel.

10. Peel non drive side of tire bead away from rim at bead seat hook.

11. continue all the way around

12. pull out tube, starting 180 degrees opposite of valve stem.

13. At the valve stem, push the valve stem/tube out of rim.

14. Remove tube.

Replace tube:

1. Partially inflate tube. (enough to give it shape. that is all.)

2. Place valve stem in thru the valve stem hole in rim.

3. Lay/feed tube into tyre along the diameter of the rim.

4. Place the non drive side of the tyre bead onto the rim, starting at the valve stem. Be mindful to ensure that the bead of the tyre is actually below the bead seat hook of the rim.

a. Push stem up to help get inner tube into the tyre. (if needed)

5. Work into place the remainder of the tyre bead.

a. make sure the tyre bead is in the rim and that no inner tube is protruding.

6. Inflate to specs. In this case 8.5bar

7. Close presta valve, and install valve stem nut and cap.

8. Place rear wheel in frame.

a. We know the bike is shifted into “Little/Little”, so we place the chain on the small cog when we place the rear wheel into the rear dropouts.

9. Place bike on ground, and readjust QR/rearwheel/axle in dropouts if needed.

a. Make sure the wheel is in the frame correctly.

10. Hold bike up and shift the chain into about the middle of the cogset.

11. Ready to roll....done.

peace...d
