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.
29er off-road version
Have you considered adding a 700x50 or 700x55 version of this tire? This looks like the perfect trekking tire for gravel-road tours on a 29er.
Thanks.
