Why We Like The S-Tubo Road Tube
Tubes are the first step in having a fun and safe ride, so we take our tubes seriously and install the Tubolito S-Tubo Road in our fast road wheels. The S-Tubo is only 23g, or about 75% lighter than our regular rubber tubes, and rolls much smoother. This tube is the closest we're getting to tubeless without the need for messy sealant and tubeless specific tires.

Lightweight, compact, and great
- Familiarity:
- I've used it several times
I carry two in my saddle bag and they take up less room than one butyl tube. Blow into the stem b4 installing to give it some shape to install without twists or wrinkles. Lightweight, compact, and great tubes. Used them when damage to tire was in excess of sealant ability.

Garbage
I went to pump it up after I installed it and it popped right near the valve close to the seam where the plastic was thin. I want my money back.

Much better options
- Familiarity:
- I've used it once or twice and have initial impressions
I have used vittoria and ridenow TPU tubes. These seem to be more difficult to install and don’t retain air at all. Put a pair on my bike. One held air for 24 hours the other went flat in 3 days. Bad product. Vittoria and ridenow are great and ridenow is very reasonably priced!!

S-Tubo Road tube 42mm valve, pair review
- Familiarity:
- I've used it several times
Hmm, Guess I should have read better. The MTB S-Tubo apparently have removable stems, the "road" version clearly states it does not on the "tech details". I missed that, I run 404's that require a valve extender. I did actually unscrew the valve stem and use a extender, but I'm 100% I voided any warranty etc. in doing so. MY BAD. Having said that, I blew air in with my mouth, mounted everything and it was "easy", no problems. They seem to actually hold air better than my previous lightweight racing butyl tubes, so that's a positive. I haven't had a puncture, but that was never an issue for me, so I'm not a good judge of puncture protection. I'm not supposed to mount to "rim brakes" and ride hills, but per my infrared thermometer and testing, I haven't demonstrated any temperatures of concern for myself. I certainly cannot endorse, nor recommend, but I'm simply stating, I measured mine in my local area with a infrared thermometer after riding hills. I wasn't concerned with the data my thermometer provided to me, so I'll continue using. They are soft and the ride is nice in conti'5000's on zipp 404's with a standard carbon road bike. Happy riding, may your PR's seem easy and your chamois comfortable.
