SchwalbeAerothan 700c Tube(Return to Product Page)

I haven't had to use this tube yet as it is a spare for my tubeless wheel but it looks nice and I am hopeful it will be a lightweight option that works well when needed.

Really light tubes, however they don't hold air as well as butyl tubes. Better than latex though.

Extralite and packs small so is the perfect extra tube - once installed the rolling resistance is minimized and the feel of the bike is improved too!

With the weight savings and being able to reduce tire pressure, the ride feels like tubulars.

Highly recommend these!

I bought this tube based on a friend's recommendation to replace a latex emergency tube for gravel racing. I haven't had to use it yet but it is super light and more durable then the latex.

There is no denying that this product, be it the batch or whatever has a serious and dangerous design flaw. Upon inflating the seated tubes for the first time to 30psi just to get the tyre seated evenly and to check it over before inflating to 85psi the valve core simple blows out. It is inevitable that a plastic valve barrel won�t provide enough hold strength over the valve core. Shocking oversite.

After a lot of indecision, splurged and bought two of the Race 700 x 23/28 version. Disappointed to find that both weighed nearly 46g (45.7 and 45.9g to be precise). Substantially more than the 41g listed both in the specs and prominently on the box. Hoped that the scale was off. Fresh batteries, re-calibrated. Nope, not the scale.

Schwalbe tech rep says that lower weight is less important than reduced rolling resistance and greater puncture resistance. CyclingTips' posted data shows that Aerothans have slightly more rolling resistance than latex and slightly less than Conti Supersonic. As for puncture resistance, it's always seemed like that should be in the tires rather than the tubes (though resistance to tearing while mounting is always welcome).

Still, one expects that a product which is (a) made in Germany and (b) so expensive would be closer to spec. If that's impossible, a weight range should be given.

They're still in the box, so my one star rating doesn't mean much. Haven't decided whether to use them or return for credit.

Pros: lightweight, packs small, holds air very well, perfect for seat-pack spares

Cons: Cannot be permanently patched with any patch material currently on the market. I've tried Tubolito, slime, and Park patches. Nothing works. Schwalbe says you must use their patch kit, but I've never tried it because these are not available anywhere. Until Schwalbe makes their patch kits as widely available as the tubes, these can only used as a seat-pack spare (unless you want to throw away a $30 tube with each puncture). Note: Tubolito patches work great for a while, but after a few months they eventually fail.

Been using these instead of tubeless on my road bikes. One flat in 3 years and 15k miles. NUFF said. If you don�t want to mess w tubeless but want great ride quality, light weight, puncture resistance without the hassle of tubeless, this is it!

Same experience as Aaron below. These are light but not reliable. My valve blew out after pumping it about 80 psi and thread ruined and not able to hold air literally after 2 rides. Won't be buying this again.

I will never use a "normal" tube again! It is a phenomenal improvement. It frees up so much space in your Jersey or bag, and they really are puncture resistant. The also prefer them to their orange competition. Cannot recommend enough!

Lighter than latex, and it holds air better than butyl, with virtually no pressure loss between rides. Some reviewers have said they're hard to repair, but in my experience punctures are easily repaired using either the Schwalbe or Tubilito patch kits that are specifically made for thermoplastic tubes. They are great to carry in the flat kit since they are light weight and take up much less space than butyl or latex.

I bought this to use as a spare on my tubeless gravel bike. However, the paperwork that comes with it says not to get it in contact with sealant. So, it is useless for my purposes. I bought lightweight tubes from another company that do not have this issue.
