Anyone else sad the 36" foss tubes are gone?

I noticed on UDC they weren’t available. They’re not making them anymore. I contacted FOSS and they indeed stopped making them. Btw, I always thought it was John Foss who created these tubes but it wasn’t. At first, I thought these tubes were kind of weird, but really grew to like them. I had one last over a year and over 2000 miles. The only reason it failed was because once again my rim strip failed.

I have a few regular 36 tubes now but you can immediately feel the weight difference. I have 1 FOSS tube left though…

You snooze, you truly lose… I was going to order 10 of these 2 years ago but said to myself they’ll be right here on UDC…nope.

Do you think 36" FOSS tubes were light? Then, you’ll love the 36" TPU tube from 36pollici:

If you’re not keen on spending €65 for 2 tubes, you may use a cheap €5 29" Butyl tube. They can be extended to fit a 36" wheel, while being lighter than FOSS tubes.


Wow. This is why I love this forum, thank you. That is not bad for 2, the fosstubes were like $42 each. I am definitely ordering some of these.

My electric pump is sad it will have nothing to do every week.


At your own risk, but TPU tubes can stretch a bit. I’d try a large 29+ type off AliExpress and see if you can get it to fit as well.

Yes it is.
