Tell use what model Dahon, please, and what mods.

If you replace the fork, hopefully it has similar geometry in trail and rake, and is internally threaded for the headset preload bolt on the folding handlepost base. Note: Not all Dahon forks have the same length steer tube, older is longer, so since I was using an older steel handlepost, I needed to retain the older fork, when I replaced the frame with a newer one when the old frame cracked.

Mine is circa 2004 Speed and I've modded it for 2X crank and front derailleur, mid-cage (GS) rear derailleur, front and rear racks able to hold full-size panniers, aero handlebars, and an improvised Deltech cable.
