Thanks for this soundwave. I have just put my order in. I have never had tubeless tyres as a couple of things were putting me off. One was the cost of these types of pumps (so that's now sorted).
The second thing that has prevented me from getting some is as follows.
A friend of mine has had some and took them off fairly quickly as he found the following problem.
He said they seemed to loose pressure very quickly when left for a couple of days. So unlike normal tyres he found he had to put air in his tyres before virtually every time he went out on his bike.
Have you found the same thing, and is this a common problem?
