ProsLight, holds pressure
Using on my Moulton, running at 115psi. I blew a hole in one coming down a steep 15% descent ... but because I was over braking to stay with a cautious friend. However it took about 10 seconds to go flat allowing me to stop safely.

ConsOne valve wasn't screwed in tightly enough hopefully just a one-off.
ProsWell made, stylish clear dust cap
This is the tube that I normally use in my 100psi Moulton. It copes well even if I use it in a Schraeder hole. I did get a new one where the valve wasn't screwed properly in and it went flat in a couple of days. A quick touch of the pliers made the tube usable, so nothing lost except an hour of my time tracking it down.

Do these tubes have removable valve cores - for valve extenders please?
Hi there,

Unfortunately these do not have removable valve cores I'm afraid.
