Is that for the "normal" or "lightweight" variant?

As I understand from the website, the lightweight, or "S" variant is ONLY intended for spare use...

I've got two Tubolito tubes in the 650b wheels for my gravel bike. So far no flats but... that doesn't really mean anything. No crr data either, sorry.

I also have two of the "tubo road" tubes for a spare for my TT bike and they are TINY and weigh nothing. That is, honestly probably the best use for it. Two tubes, a multi-tool, two CO2s, and inflator fit in the draft box of my Speed Concept with tons of room to spare. Thinking about making a foam cutout of some sort to organize all of it. Right now I just stuff a pair of socks in there to keep it all from rattling.

I just looked at the website and it now says "disc brake only"

yes, the S-version at 23gr is denoted "disc brake only"
the normal one (38 gr) is ok for rim brakes. i am using the latter since a year now and no issues so far. no flat yet. seems to hold air better then a light butyl
cannot comment on RR but does not "feel" different then a thin butyl.

From real world riding experience, they provide no better or worse puncture protection than normal butyl tubes. I don't use them personally, but guys in my riding / training group have punctured them on a few occasions. Both the small wire / glass type punctures and a pinch flat. Given their cost, no way I would buy them for their puncture resistance claims and regarding the rolling res. data that has come out which shows they are only marginally faster than butyl.

The only benefit I see in them, as others have said, is to have it in a flat kit due to their size. Race with latex.

From what I'm seeing, the S-tubo is very comparable to latex tubes, unless I'm missing something?

Thinking about ordering one myself.

I have 2 on my gravel bike. No complaints here and the room they save in my bag is great.

Also, someone mentioned the cores are removable, but on their website it says cores are glued in place and non removable. I have Zipp extenders, so I need to remove cores with them. Any one have further insight?

That's the first data I've seen. Kind of what I expected to be honest: rolling resistance similar to or slightly less than light butyl (when you compare apples to apples, the S-tubo is really only meant to be a spare)

I also did eventually test a regular Tubo Road myself a while back, and it had terrible CRR - an increase of about 0.001 over latex (~10 watts for 2 tires at 25mph). I can't really see a use for them myself, but I suppose they do let you carry two tubes in the space of one, so if you want to be able to change two flats and don't want to make more room then maybe? They *look* pretty fragile though, so not sure there's a real use case for them. They're also ridiculously expensive and AFAIK can't be patched.

There's a tubolito-specific patch kit that they sell. Honestly, the material itself seems pretty damn tough IMO. As you and others have said, the best application is saving space and weight in your flat kit.

I emailed them about the S-tubo being a spare only. This is what I got back, "thanks for approaching us and your interest in our tubes.
Basically you can also use S-Tubo-Road as your daily tube. While Tubo-Road is twice as robust against punctures as standard tubes, S-Tubo-Road is still as robust as standard tubes. To see how we test that you can watch following video:

I hope that answer helps.

Please do not hesitate to come back to me with any questions."

So seeing as the S-tubo can be used as an every day tube, and the rolling resistance, particularly at lower pressures, is in line with latex, does that change your opinion? From what I'm seeing, the cost is the only downside.

I'd like to see that puncture test with latex.

Where did you come across that data, if you don't mind me asking?



Seriously, don't take me too seriously.
