Self sealing tubes
Used for 3 to 6 months
Bought these for a CX Sportive (I didn’t want any punctures).
Easy to fit but make your wheels quite heavy.
One of the tubes after inflation sealed its valve, so I cant pump it up anymore. But it doesn’t seem to have lost any pressure (so I guess less of a problem than I first thought). Bought a spare tube to replace that one when it eventually deflates.
