Replacement integrated saddle and seatpost for Rothan. "Scoop shaped" saddle is different to a pedal cycle saddle and better supports the child while they scoot, preventing them from pushing themselves off the front of the saddle. 25.4mm diameter. Seatpost is 240mm long, which is longer than the one supplied as standard with Rothans. Choose if your child needs the saddle to go higher than the current seatpost will allow.
