These extremely high quality tubes fit a 26" (559) tire from 25mm to 40mm or 1.0 to 1.5. The SV12A tube is a presta valve.
Punctures become obsolete with the MARATHON PLUS! The SmartGuard layer made from a flexible, special rubber offers particular resistance to shards of glass and flints. Even a thumbtack cannot penetrate this protective layer. The SmartGuard belt does not increase rolling resistance. The MARATHON PLUS rolls as easily as a tire without protection.
