We had a bike in today with a puncture .

Nothing strange with that except it had a tube in a tubeless tyre and wheel.

As you know a tube has a metal valve, a tubeless one has a rubber one. This bike had a special nut that fitted that went over the valve as normal but it had a lip that went in to the rim stopping the valve from moving about.

Anyone know where I can get some of these gadgets? They used to be sold back in the eighties but not seen them until today.

never seen one got any pics pls

no but you know the round nut that you tighten up to hold the valve against the rim its that but it has a hrrl that fills the gap around the valve and rim

My innova has a tubeless tyre but it must have a tube because of the spokes.

this device is so you can fit a tube to a tubules wheel
