Schwalbe Tubes for 650B and 26″ Tires

Schwalbe Tubes for 650B and 26″ Tires


Quality tubes can be hard to find, and we have had problems with split seams and valves coming loose on ‘no-name’ tubes. Schwalbe’s tubes have been very reliable.

Presta valve.

Sizing advice: Where two sizes overlap, we recommend the smaller size. Quality tubes can stretch, but a tube that is too large will be difficult to fit into the tire.

SV11A (96 g) is for:

  • Elk Pass 26″ x 1.25″ (30 mm)


SV12 Standard (149 g) is for:

  • 650B x 32-42 mm
  • 26″ x 1.5″ – 1.8″ (35 – 44 mm)


SV13 Standard (183 g) is for:

  • Switchback Hill 650B x 48 mm
  • Rat Trap Pass 26″ x 2.3″ (54 mm)


SV14 Extralight (60 mm valve, 130 g) and SV14A Superlight (40 mm valve, 108 g) are for:

  • 650B x 37-48 mm
  • 26″ x 1.5″ – 2.3″ (35 – 54 mm)


Made in Indonesia or Vietnam.

Note: Currently, there is a tube shortage. Please limit your order to a maximum of 6 tubes (all models). We’re all in this together. Thank you for understanding!

  • Presta valve
  • Removable valve cores
  • Note: The packaging on some tubes is marked 26" and the SV14A may not note compatibility with 650B (ISO 584). Don't worry: These tubes are compatible with our 650B tires. (The diameter of a 650B tire is only 4% larger than 26" tire, and tubes easily stretch that much.) The SV14A is what we use in our own 650B x 42 tires.
