Hi all!....wondering if anybody knows what were the dates that Brompton changed there front fork specifications and what exactly were they esp regards Steerer tube,offset, fork blade length or anything else I know they went from 1” to 11/8” early on but at what date and whether there where any other changes of any consequence. My Brompton is an early one from 2005 with a stretched to 100mm fork for the Nano motor.... need to narrow it down now to possibly install a SWYTCH kit of 75 mm across drop outs. Presume it’s best to go with another set of original sized forks?Looking to buy them used if possible. Any help appreciated. Thanks T
