Aerothan 29inch — the High-End Alternative to the Basic Bicycle Tube

The Schwalbe Aerothan is a material that completely redefines bicycle tubes: extremely light, with maximum puncture protection, and designed for minimum rolling resistance.

Aerothan tubes consist of 100% thermoplastic polyurethane (TPU), including the valve, and are therefore fully recyclable. This next generation of bike tubes sets an impressive standard for weight, puncture protection, ride feel, effortless installation, and the dimensions of packaging.

Specifically made for road bikes, MTBs, and all-round purposes, Schwalbe's innovative high-end 29 inch mountain bike tube tube combines seemingly opposing features — the lowest weight with the high level of puncture protection.

The Aerothan is the result of the Schwalbe innovation hub redesigning material compositions and construction principles, to make entirely new products. Developed in cooperation with BASF and with experts from the German plastic manufacturing industry, the Aerothan tube emerged to not only meet all the requirements of a high-end bicycle tube but to exceed them.

Features of the Wonder Material — Aerothan:

  • Fully light-weight, right to the valve - about 40% less weight than a comparable Schwalbe extra light tube
  • Puncture protection newly defined - the material itself prevents sudden air loss
  • Minimal rolling resistance - maximum riding dynamics
  • Extremely heat resistant - certified for rim brakes
  • A stable ride - even with low air pressures
  • Easy installation - without slipping or pinching
  • Made in Germany
  • 100% recyclable
  • Aerothan is compatible with the Schwalbe Glueless Patch Kit only

  • Note: While these tubes are the latest in technology, there is still no guarantee against puncture or failure. Aerothan products do not qualify for a refund or replacement.

    Lightweight and no flats

    I have several bikes and don't ride any one of them often enough to want to use sealant and go tubeless. Especially over the winter, when they sit idle for 4-5 months. The sealant will dry up and I'll have to dig it out to add some fresh sealant more often than I want to deal with. These tubes are expensive, but might be cheaper than refreshing sealant in the long run. They are light, they hold air pretty well, have decent rolling resistance, you can move them from wheelset to wheelset, and I haven't flatted yet.

    Stay Away

    Bought 6 tubes for 2 bikes. None are now useable as the Schwalbe patch kits due not work in hot conditions. Cooler conditions, everything seemed good, but when the weather got hot the patches failed. The patch developed a spider web series of air channels that leaked air. Several very carefully applied patches all failed and so did the new Park super glue patches. Vulcanizing patches not recommended by Schwalbe. My earlier review before punctures now cancelled. Shame on Schwalbe, obviously released when not properly tested.

    Top Notch Tubes

    I'm old fashioned and still prefer to run tubes. I've tried the messy tubeless stuff and it judt didn't work for me, always having to add sealer when it dried up and they never seem to hokd air. So back to tubes I went. I've been using the Maxxis Ultralight tubes and they were just okay. They weigh around 157 grams fir the small 29" tubes. They've worked well but also seem to lose air rather quickly. I decided to try a set of the Schawlbe AEROTHAN tubes and couldn't be more impressed!!! I run the smaller 29" ones and all have weighted in at around 90 to 97 grams, which is a great weight savings over my ultralight Maxxis tubes. After I installed the AEROTHAN tube I aired them uo and have noticed that they hold air better than anything I've ever used. They are on the expensive side fir tubes, but from what I've got out of them, they are worth ever penny!! I know have sets in both my mountain bikes and a few extra for spares.

    Aerothan tubes

    I was so excited to try out the Schwalbe Aerothan tubes after reading about them and watching the information on them available on the Schwalbe website. That excitement deflated as quickly as both of these tubes - that is within minutes. I cannot, repeat, cannot recommend these. I am no novice at tubes/tires and I carefully followed the instructions, but these tubes won't hold air. It is just as ridiculously simple and ridiculously expensive as that.

    Seem to be a little bit small for a 29"tube

    I had to really work these tubes to get them to stretch around my rims. I'm not looking forward to getting a flat out on the trail and having to put a new tube in. Once the tube is inflated it seems to work out ok.

    better than buytl

    These tubes are lighter and hold air better than butyl. This will allow me to carry .25 cups of extra water because of the weight savings. 2 wheels plus spare tube and you can carry .75 cups extra water for $90 bucks. Weight weenies rejoice.

    nice alternative to tubeless

    Wintertime in new england, changing tires often, no need to mess with sealant, I forgot how easy tubes are and these are super-light and reasonably tough, you can use glueless patches too, they are a little strange to install as you have to stretch them a bit, but you'll get used to it.

    In development for more than 5 years, Schwalbe's Aerothan inner tube promises to turn conventional thinking on its head with an all-plastic construction that dramatically lowers weight without sacrificing durability or puncture protection. Does the Aerothan live up to the advanced billing 14 and price? That is the subject of this month's product review at the BikeTiresDirect Strava page.
