Schwalbe SV17 Inner Tube - 700c
Schwalbe SV17 700 x 28-45mm Presta Tube - 40mm Valve
Extremely airtight! The Butyl rubber compound prevents pressure loss and fewer occassions to inflate. Extremely reliable! Quality control for safer cycling: Each tube is checked twice at the factory to ensure safer cycling. Having the correct pressure means fewer punctures and reduced rolling resistance
VINCE I like Schwalbe inner tubes, but just sometimes the valve becomes loose (a drop of locktite sorts that); just carry that spare.....
Mr Watson I purchased these tubes for gravel bike tyres. They accommodate a wide range of tyre widths and are reasonably priced
Hugh Good quality, no punctures so far!
Phil The Hill good reliable inner tube
W412ren Does the job, easy to install and so far more reliable than the Impac versions that Schwalbe also have a hand in.
Phil The Hill Good quality inner tube
Mr Millgate Schwalbe inners do the job and are unlikely to let you down.
Andrew Good quality inner tube that holds the pressure (unlike the cheaper types).
Dave Best tubes out there, and this was by far the best price I could find.
