20 inch inner tube for narrow diameter tyres
Why choose this inner tube?
Because not all inner tubes are the same.
Schwalbe test all tubes (twice), including inflation for 24 hours to ensure they don't lose air pressure.
Less lost air means less time inflating and more time for you, whether it's riding, in bed before work or at the office.
Manufacturers code: SV7A
