Schwalbe MARATHON PLUS 24x1.75 47 - 507 940g Smart Guard Reflex
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.
