Featuring patented Fusion technology, Dahon's forks integrate seamlessly with the frame and handlepost. Integrated forks use a patented coupling system to connect to the handlepost, resulting in 30% additional stiffness of the handlebar assembly. The “shoulder” on their integrated forks butts against and is supported by the wider headset when encountering directional forces. Curved and finely tapered legs add a touch of flex for increased comfort. 20" wheel bikes only of the type described with 87mm headstock. Blue Supplied. The handlepost used must be the Aluminium Radius or Radius V (not the earlier steel fixed height handlepost as these require a slightly longer fork steerer tube) Note: Does NOT Include Magnetix plate
