A tubeless tire must be completely sealed to the rim
Before inflating a tubeless tire, you must make sure that the connection between the rim and
tire is correct. This connection must be even more secure than that of the conventional tire. If
you are using tire levers, be careful not to damage the rim or the tire itself. If any of the surfaces
is scratched, installing the tire could cause leaking problems.
If the tires are well fit to the rim, the interior pressure of the tire is enough to maintain the seal.
You do not need a compressor to fill the tires. A good pump will suffice.
Installing the valve
- Align the holes of the rim and the rim tape for the valve.
- Align the valve head with the holes above and push the valve through the rim tape and rim.
- Screw the tubeless valve stem lock nut with your hand. There should be no space between the
rim and the valve.
- Check that the rim tape is properly in place.
Installing tubeless tires
- We recommend dampening the rim and tire with soap and water to facilitate installation.
- Starting with the area opposite the valve, insert one side of the tire inside the rim.
- Repeat this action with the other side of the tire.
Inflating tubeless tires
- Inflate the tires until the pressure reaches 4atm.
- Most tires have lines or markings just above the chafer.
- When the tire is properly positioned, these markings should be uniform around the rim.
- Once the tire is properly fit onto the rim, finish inflating it.
WARNING If tubeless tire pressure is low, you could lose control and fall. Do not use tires with
under 2atm of pressure.
Removing tubeless tires
The area of the rim where the tire rests is very thin. Therefore, you will need to rotate the tire to
remove it from the rim.
Allow all of the air to be released from the tire.
Spin the tire while removing one of the beads of the tire from the rim. Once it has come out
completely, remove the other bead, starting at the valve.
Installing an inner tube and tire
A standard tire can be used with an inner tube.
Make sure the rim tape is covering all spoke ends and nipples.
Install the inner tube and tire as you normally would.
Converting to a tubeless tire
- Remove the tire and inner tube.
- Make sure the rim tape is covering all spoke openings.
- Follow the instructions for installing a valve.
- Follow the instructions for installing a tubeless tire and inflate it.
Removing the rim tape
- If the rim tape is going to be used again, be careful not to damage it.
- Follow the instructions on how to uninstall a tubeless tire and the valve stem.
- Insert a screwdriver through the valve opening of the rim tape, between the rim tape and the
rim.
- Lift the rim tape with the screwdriver and insert a tire lever under the rim tape.
- Using the tire lever, lift and turn the rim tape upwards and outwards from the rim.
Installing rim tape
- There are two types of rim tape, one for symmetrical rims and one for asymmetrical rims. Con-
firm that you are installing the correct type of rim tape for your rim. If your rim is asymmetrical,
make sure it is well aligned.
- Check that the rim tape is in good condition, without scratches, holes or deformities.
- Align the opening of the rim tape with the hole in the rim for the valve.
- Insert the valve stem through the rim tape opening.
- Using your fingers, lift and stretch the rim tape so it is situated in the rim cavity.
- Complete the tire installation procedure.

INSTALLING THE TIRE

These instructions apply to standard wheel systems where the air inside the tire is retained by
an inner tube. Follow these instructions for repairing and replacing the inner tube or tire.
Removing the wheel
- Follow the instructions for opening the brake in the braking system section.
- Follow the instructions on how to remove the wheel in the wheels chapter.
