Foss tubes

vorsprung

I've put some Foss tubes on my best bike.

These are kind of "super" inner tubes

Anyone else tried them?

I use Conti Supersonic tubes, cost about £10 and at 50g about half the weight of the Foss tubes.

Foss tubes *claim* that you can stick huge sharps into the tyre and they do not deflate. As I am doing, um, over long rides this is quite an interesting claim. The lower weight is a bonus. It's lower weight + reliability that I'm hoping for

Good tip on the supersonic tubes though, could put some in the time trial wheels

Yes I found that with a google but they are (not unreasonably, it's weightweenies!) simply interested in the weight.

Remember, I weighed my current tubes and the new ones and hurray I was a winner. For me the weight question is answered.

I'd be interested to know if anyone has run over sweepings from a nail factory or how the tube responds to heat of heavy braking and anything else! I have them on the bike so I will answer the reliability question myself in the fullness of time

They're DOG SLOW, like noticeable rolling resistance reduction.

On my commuter for the extra puncture resistance I've seen nothing better than a regular tube (with Conti Sport Contact tyres)

really? actually there are also posts about them failing at the seams, but also citations for being reliable

given the cost and likely small market, ww is probably the best source of info

personally i'd stick with conti race lights

No one has mentioned Latex inner tubes. I wouldn't swap them for anything.

Latex everytime, so smooth, light, and fast rolling and do seem to help with reducing flats

Update after a couple of months use. I haven't run over any huge wood screws so I can't say if the tubes advertised ability to seal punctures works. One downside I've noticed is that they tend to loose pressure faster than standard butyl tubes

Iĺl stick with my latex tubes then thanks.

Using Foss inner tubes on my 36er bike have had no problems from them at all. Weight of the inner tube 224 gram (36inch 1.75-2.25) with Nimbus Nightrider tyres (36 X 2.25). The weight of the tubes was the attraction.
Seen comment deflates quicker not found this myself.
Ride over rough ground even thorns without any punctures so inner tubes seems very durable and comparable to latex inner tubes. Not tried riding over screws or nails tend to avoid while riding as most sensible riders would!
