Why choose this inner tube and not something cheaper from another manufacturer?

Because not all inner tubes are the same - you can feel the thickness and quality in the Schwalbe tube.

Schwalbe test all tubes (twice), including inflation for 24 hours to ensure they don't lose air pressure. 

Better retention of air means less time inflating and more time for you, whether it's riding, in bed before work or at the office.
