Foss innertubes

I have brought two of these inner tubes, while I have to pump them up every morning before I ride the most crappy thing about them the valve stem has come apart about 10mm up from the innertube itself! Anybody had this trouble?

Ahhh yes, I had that same issue, small hole near the bottom on the valve stem where it rests on the tube. I chucked it out in the bin :(

It needs to be reinforced with extra layer around the base of the valve, I think its a weak point as it does split, shame really as I start to like em despite having to pump em every time as I have noticed when fully inflated at max 120 PSI ( depends on tyre PSI settings ) the tube seem to leak slowly down to 60-80 PSI the next day

For money's worth- I don't think they are worth $20, I would be happy to bulk buy normal 700x23 tubes i.e. 6 tubes for $26

hmmmmm sounds like it might be a design fault!  Will have to let the LBS know so they can pass the word.

Yes, have sometimes seen that on rubber inners, ie the rubber of the inner, separating, from the brass of the valve. Only occasionally; and only on years old tubes. I don't know any way to fix it.

Had the same problem as RD6. I paid $16 but this is too much when they have a design fault. One think in their favor is they won't burst and wil leak slowly. Had a thorn in one and was able to ride quite a few Kms.

Same here - broke away at valve/tube joint - bike was leaning against clothes line at the time it went.

Also - leaked as RD6 has mentioned - put the 9 month old rubber tube back in - happy again, cant really see me ever using them again.

I have 6 and no problems other then they do lose a bit of pressure.  Every third day I pump them up. What pressures are people running them at. I never run higher then 100psi on the back and 90/95 front. Same when I used to race.

110-120 PSI as per tyre recommendations, FOSS tubes should be able to withstand that
