• Hi there,
    Pretty sure it was 110mm or slightly wider like 112mm.
    Goes really fast too!

    I'm really curious now, as building the Grubb as a 3/4 speed would ace.

    Do you have any more pics of this on flickr or anywhere ?

    And with regards to the sturmey archer hub, did it have a particular model number ?

    Cheers,
    James
