The popular allrounder is now available with extra safe 3 mm GreenGuard puncture protection.
The insert of highly flexible natural rubber is 3 mm thick. Its inner values are also "green". A third of the GreenGuard is produced from recycled latex products.
Old products of natural rubber (such as gloves, inner tubes …) are shredded and, after several process stages, are again used as basic material in the puncture protection inserts.
