To ensure that even small passengers are safe and secure on the bicycle, Britax Römer has developed a large spoke guard for the Jockey child seat. The spoke guard, which is directly attached to the child seat, prevents children's feet from getting caught in the spokes, significantly reducing the risk of injury. The Römer Comfort is suitable for touring and sports bicycles. The seat post must be round. The Jockey Comfort features a multi-height adjustable headrest, allowing it to be optimally adjusted to the child's size without having to unthread the straps. The Römer Comfort is compatible with touring and sports bicycles of sizes 26’’ and 28’’ with a tube diameter of 28 to 40 mm and a rack width of up to 150 mm. The seat post must be round.
