Aerothan 27.5 inch — 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 27.5 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.

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.

I use these tubes in both of my bikes, as I decided to not run a tubeless tire setup. For my MTB, I will be changing the tires somewhat frequently to match where I am riding (Schwalbe Johnny Watts, Eddy Current, and Nobby Nic); the mess of dealing with a sealant for these changes is something I want to avoid. Paired with these tubes are Tannus Armour flat protection inserts, along with heavy casing tires. If I do experience a puncture, I can quickly patch and go, typically while leaving the wheel on my bike. For others, I definitely see the advantage of running a tubeless setup, which I did consider for myself. In the end, I prefer to have these tubes, Tannus, and tire combination.
For my SUB (Sport Utility Bike), I also use these tubes along with Tannus Armour inserts, and Schwalbe Pickup tires - tough, with great flat protection. I commute everywhere I need to go on this bike (sold my car last year), and I do not plan to change these tire often, as I do on my MTB. I simply like the idea of being able to patch a flat, in the remote case that happens, without cleaning up the mess of tubeless sealant. In the colder winter temperatures of North Carolina (US), this seams to be the better of the two setups for me. My fingers will still become quite cold when patching a flat, but they will not be cold [and wet] from tubeless sealant.
I have had a slow leak in my rear tube on my SUB, which I have not taken the time to patch yet - going on two months. This tube material does not tear/rip open like butyl rubber tubes do. I just anticipate that I will have a challenging time finding the hole, even using soapy water to hunt for bubbles from the air escaping through the hole. The valve could be the culprit, as I have had one defective tube with a bad valve - it had a bad valve movement - ;) . Because these tubes are relatively expensive, I would prefer to not just pull and replace it, but I will if needed. My experience with that one defective valve, and the price, are the only two negative aspects of using these tubes that I have experienced.
The weight is great! When I commute, I have a tool kit bag that I carry in a pannier; I have one of these tubes in it for myself, but patches and other items to help others if I see someone stranded. There are so many tire types and sizes on the bikes I see people on out on the road, that I could not carry enough tubes to help people. On my MTB, though, I carry one of these tubes in my size (smaller diameter of a 27.5" for the Tannus insert), and also one of these in a 29" size to have ready for someone else; that is the more popular size now from what I have seen. The weight penalty is so negligible, the benefit of being able to help someone else far 'outweighs' that.
Another characteristic that I like about these tubes is that they are better suited to recycling than rubber tubes. I have not found a company nearby where I can take these to be recycled, and Schwalbe does not provide specifics for this, but I will hold on to any used Aerothan tubes until the recycling pathways are established.
