Just In – Foss Inner Tubes

Puncture resistant, lighter, eco friendly inner-tubes from Foss

by VecchioJo   November 19, 2012  

Everybody hates punctures, which is why newer better puncture-resistant inner-tubes are constantly being invented, and the gravelly side of the road is littered with their flaccid carcasses as for a variety of reasons they fail to beat the general all-round user-friendly convenience and cost of a normal inner-tube.

The latest tubes to step up to the challenge are these ones from Foss, who claim their tubes are not just puncture resistant but also lighter and more environmentally friendly than your normal inner-tube, quite the triple whammy. Each is a bold claim by itself, but as the Foss website proudly proclaims they’re “a unique, energetic, strong conqueror”. And who would dare argue with that?

First off, Foss tubes claim high puncture resistance because they’re made from a highly polymerized un-vulcanized rubber composite, which is special because if punctured the tube material forms an air-tight seal around the thorn, nail or puncture intent sliver of glass, retarding the speed of the leaking air. This means that you won’t know you’ve punctured as long as the offending item is still in the tyre, or at worst it will go down incredibly slowly, allowing you to get home. However should you get a hole you’ll need to fix it with one of the special self-adhesive patches that are available at £3.98 for six.

The Foss tubes are environmentally friendly because the modified thermoplastic elastomer compounds (TPE) they are constructed from means they can be recycled with other TPE products, thus minimizing waste & protecting the environment.

And if all that wasn’t enough Foss say their tubes weigh about 30% less than other tubes, and they have blue valves, which is cool.

Foss tubes cost £19.99, so they’ll need to be about 4 or 5 times better than a standard tube to be worth their while, which is not an insignificant challenge, even for a strong conqueror. The tubes come with their own special rim-tape which is designed to stop the tube slipping and pinching in the tyre and are available in 20x1.35-1.75, 20x20-25c, 26x1.35-1.75, 26x1.95-2.25, 29x1.95-2.25, 700x20-25c and 700x35-45c sizes.

These Foss inner-tubes come with incredibly specific instructions for fitting, which doesn’t help with the trepidation brought on by newer improved lighter better inner-tubes thanks to experiences with new improved lighter better inner-tubes in the past, swearing by the roadside in the cold and dark, and rain. But we’ve got some of these blue tubes for the road bike and some for the cyclo-cross bike to hopefully put those demons to rest.

Can I put Stan's sealant in them? Or more to the point, if I do put stan's sealant in them, will it still work???

I hope that's not a smooth valve stem that your pump blows off at about 80psi. Looks like it Sad

Un-vulcanized?? They have still to get Spock's approval then? Big Grin Big Grin

I'll get my coat and on the way I say, unless the are indestructible, £20 is a bit expensive

Oh my god... just read the instruction manual


The price is stupid, the fitting terrible, if you do not follow instructions they will blow up and you will be killed !

Nice. My stock of Air-Bs is finally starting to dwindle so these look a lovely replacement.

Am always happy with my Michelin A1's at £3.99 a pop Smile


I will pay >£20 for a tyre but never an inner tube.

A quick look round teh interwebs reveals that they can be had for a tenner. Still pricey though, but I do like that blue

I do hate how hard it seems to be to recycle normal tubes, but playing devils advocate, how much more environmentally friendly is an innertube shipped from Taiwan vs Michelin ones shipped from France?Thinking

Does anyone actually recycle tubes? Seems to me that most people throw them into trees for the fairies to remove.

Yes, its quite an interesting thing, but not recycling in its normal sense

I wouldn't dream of chucking one away while I'm out unless there is a litter bin. Messing up the countryside is a shitty thing to do.

In theory, there is no difference between theory and practice, but in practice...

I've never seen an inner tube discarded in the countryside, nor seen a fellow cyclist do anything but take a damaged item home with them

you'll be saying cyclists throw plastic bottles in hedges next

Feel free to order tubes from the shop here: http://tinyurl.com/fosstubes. They are wheelbuilders in Poland (www.facebook.com/kolarowerowe).

The best way would be to simply send email to sklep@daveo.pl and order directly desired amount. Guys speak perfect English there and are able to give you discounts for bigger purchases.

Available sizes:
* 26/1.95-2.25 - £10
* 26/1.35-1.75 - £10
* 29/1.95-2.25 - £10
* 26/2.0-2.5 [new size!] - £13
* 700/23C-25C - £10

Apart of the low prices each tube contains free rim tape. Shipping to UK shouldn't be more expensive than £20.

I looked at that installation manual. Crikey. That's a bit mental...

What's 'mental' about the instructions? A bit of massage at 0.5 psi and make sure the line is in front of the valve. Other than that, I do all the rest when installing a 'normal' tube

Maybe a minute longer by the side of the road as a result, but ... err ... you should be doing that less often if the technology works

More important than weight though is rolling resistance

More important even than that is Rule 8: the colour matches my frame (I'll know, that's what matters)

Need long valves - any ideas - I have tried a valve extender but it won't fit in the rim and I don't want to drill the hole.....
