Tyres and I don’t seem too well matched. Three days into owning the Merida, I tried to let a little air out. In the tubeless conversion process, CycleLab pumps them firm to about three bars to ensure they seat themselves properly. Steve Bowman had advised me to let them down after a couple of rides. I unscrewed the whole valve and the tyre farted out air and slime like a balloon. Tail between my legs, I returned to CycleLab where Steve very congenially reseated the tyre.
A few weeks on, I now know how to pump the tyres and let just a little air out. The next step is to fix a puncture in the field by inserting a tube. Bear in mind, you put a tube in only if, firstly, the slime already in your tubeless tyres won’t self-seal the hole, or secondly, if a plug doesn’t close the hole. Follow the pics to see how it’s done…
1. Remove flat tyre (in a race or even training situation, if the tyre doesn’t self-seal, you’ll put a tube in it to get home).
2. Pop tyre bead off rim using tyre levers (get the levers under the edge and then slide around).
3. Remove tubeless valve by unscrewing (stash the valve safely somewhere for future use).
4. Insert tube, starting with valve.
5. Work tube in under tyre, putting tyre back onto bead as you go. Work in a circle. You might need tyre levers to finish off.
6. Make sure tube and tyre is properly in place.
7. Screw bomb onto applicator.
8. Bomb valve.
Good to go!
