“The Catena 20 chain guard impresses with its design qualities, as well as its practical and long-lasting usability,” said the jury. Thanks to its individually moving lamellae, the chain guard is flexible, making it compatible with almost all chainring sizes. The clip-on trouser guard can be easily mounted for reliable safety and the rear extension is adaptable to most wheelbases. The chain guard can also be effortlessly removed and attached to another bike. The Catena 20 is packaged in its straight form and accordingly requires much less shelf space in bicycle shops than conventional rigid chain guards.
