Aerothan TPU tubes: what they are and their advantages
Aerothan is a thermoplastic polyurethane (TPU) material Schwalbe developed as a high-end alternative to a standard butyl tube. Rather than incrementally improving butyl, it's a different tube material altogether, aimed at riders who want the lowest possible weight and rolling resistance without giving up puncture resistance. Key advantages: About 40% lighter than a compaFew readersAerothan tubes: installation, repair, and care
Installation basics Aerothan tubes install just like a standard tube — the material's dimensional stability actually makes it easier, since it doesn't shift or get pinched as readily. One important limit: When pre-inflating prior to installation, only inflate an Aerothan tube until it's round and free of folds — that's roughly 0.3 bar (4.5 PSI) at most. Don't inflate it further while it's off the wheel, otherwise the tube could explode. Once mounted properly inside a tire, normal operaFew readers
