How to glue an Ori tube

Make sure the tyres are always inflated (before and after gluing). The tubular will lose pressure, so inflate it regularly – also after gluing the tubulars. Make sure that the tubular is never without pressure.

 

(Tip: hang the wheels at the wall so that they are not standing on the ground.)

The sealant that you find with your order is more than enough to prepare the tubulars after gluing and for the first use. You can always buy new sealant, but you have to make sure that you are always using Joe’s Super Sealant. If you use different sealant, there is a risk that the tubular will be destroyed.

1) Ensure that the rim has sufficient glue.

2) Mount the tubular without any air. Ensure that the valve is completely straight in the valve hole and that the base of the valve rests on the rim.

3) Pour 30ml of sealant into the tubular.

4) Pump the tubular until +/- 0.5 bar and ensure that it stays on the rim. Mount the tubular using the base tape so that it sits evenly over the whole rim. 

5) Pump the tubular until +/- 3 bar.

6) Roll the wheel in both a forwards and sideways movement so that the sealant is evenly distributed inside the tubular.

7) Leave the tubular on the rim for a minimum time of 2 hours. The longer you wait the easier it will be to glue.

8) Before removing the tubular from the rim pump some extra air into it to ensure there is no sealant blocking the valve.

9) Remove the tubular from the rim and let the air out until a pressure of +/- 0.5 bar.

10) Glue the base tape thickly two times directly after one another. As you reach the end of the tubular (where you started) it should not be dried. If this is the case apply another thin layer of glue. 

11 Apply a thick layer of glue to the rim. Ensure that you wait no longer than 15 minutes between applying the glue to the base tape and mounting the tubular on the rim.

12) Mount the tubular with minimal pressure in the tyre onto the rim. Again check that the valve is completly straight in the valve hole and that the base of the valve is resting on the rim. Otherwise you risk the chance of breaking or bending the valve.

13) Pump the tube until +/- 1 bar. Mount the tubular straight on the rim using the base tape as a guide. Finally to make the tyre roll as straight as possible use your hands to move the tubular and the profile as a guide.

14) Pump the tubular until +/- 3 bar and leave to dry overnight.

15) Once the glue is dried go for an easy 15 min ride on the wheels or on the rollers to ensure that the sealant is distributed evenly over the inside of the tubular.

Insert Sealant instruction: 

1. Shake well.
2. Remove valve core and bottle’s cap.
3. Insert spout in to the valve at eight o’clock position:
4. Squeeze bottle to fill in desired amount of sealant, you need 30 ml (1/2 bottle) for each tyre.
5. Close the valve core tightly and inflate till 2 bar.
6. Rotate wheel while shaking side ways to spread the sealant.
7. Wait for 24 hours.
8. Ride with the tyres for min. 15 minutes with a   pressure of min. 2 – 7,5 bar.
9. You will always lose 10-20% of the tyre pressure after the first ride. After this you will lose about 0,5 bar each 8 hours.
10. If necessary you can start again from step 1 if you have lost sealant.

To check sealant levels at a later date: 

1) Position the wheel with the valve at the lowest point.

2) Remove the inside of the valve.

3) Insert a metal pin (e.g. a small allen key) inside the valve and push carefully until you touch the wall of the tubular and continue until it has approximately the same diameter as

it would have whilst pumped up.

4) Remove the pin. If there is approximately 8mm of liquid on the pin then there is sufficient sealant in the tubular. If there is less that 8mm more sealand shoud be added.
