Introduction Spec

    Black version of the Sturmey Archer S-RF3 is here!

    The S-RF3 3 speed freewheel hub is equivalent in virtually all aspects to Brompton BSR hub originally equipped on the 3 speed Brompton. This kit is well suited for replacing the worn out BSR, as well as converting your Brompton into a 3 speed. 


    This kit includes the following:
    - S-RF3 freewheel hub, 28H, 111mm O.L.D.
    - Sturmey Archer SLS30 thumb shifter
    - Hub fitting kit (alxe nuts, guide nut, cable anchor, non-turn washers, indicator chain, and circlip)
    - Shifter fitting kit (gear cable, cable housing)
    - 3/32" sprocket, per selected size


    This kit is for those who cant build their own wheels. If you can't, no sweat! We can built it for you. Just see our custom built wheels section. 

    We have assembled the gear inches for various combinations of sprokets and chainrings here, which may help you select the right sprocket.
