    "Aufgrund von Engpässen und Verzögerungen in den weltweiten Lieferketten kann es vorkommen, dass der Hersteller vereinzelt Komponenten der Originalspezifikationen durch mindestens gleichwertige oder sogar höherwertige Bauteile ersetzt hat. Das gelieferte Fahrrad kann in Einzelfällen von den Abbildungen abweichen.",
    "Da das Daily Grinder 1 der Familie der Gravel Bikes entstammt, kann es weit mehr, als nur auf dem Asphalt fahren. Bestückt mit den 40 Millimeter breiten Reifen von Schwalbe, kann es das Bike auch locker mit gröberem Gelände aufnehmen. Wer das Daily Grinder 1 oft nutzt, freut sich zudem über die robuste Shimano Claris Schaltgruppe, die absolut verlässlich arbeitet."
