Furthermore, they undergo a 24-hour pressure test to confirm their durability.

These tubes offer flexibility and are well-suited for a range of bikes, including mountain bikes, CX bikes, gravel bikes, and more.

  • Valve: Presta (with removable inner core), 40mm length

These tubes are highly versatile and compatible with a wide range of tyres. You can confidently purchase these tubes if your tyre size falls within any of the following specifications:

  • 27.5″: Fits tyres from 27.5 x 2.00 to 27.5 x 2.40 (also known as “650b”).
  • 28″: Fits tyres from 28 x 1.50 to 28 x 2.40 (including 28 x 1-1/2).

These tubes work with all tyre brands.

Airtightness: Schwalbe tubes retain air pressure considerably longer. The quality and the material purity of the rubber mixture directly effects the quality of the tube. Each Schwalbe tube is individually inflated and inserted into a mould. This ensures the even wall thickness and excellent air retention.

Reliability: Consistent quality control brings with it the security of use: Each tube is inflated at the factory and stored under pressure for 24 hours in order to test the air retention.

Retains pressure longer! In comparative tests against other tubes (including named brands, own-label brands and no name products). The result was clear. Over a period of 30 days the other tubes lost nearly twice as much pressure than Schwalbe tubes. Possible reasons: Less butyl content, or lower quality of butyl. Schwalbe is uncompromising in its standards, despite ever increasing world market prices of butyl.
