never owned a Dahon. so there may be no alternatives.. Thor sells them he would be a better authority..


Just Brompton has a few different masts for their various bars and there, the mast tube is bent a few degrees forward .


I have a Bike Friday too .. tube bending is part of the builder's options .. loop stays Etc. and when Alan was making Tandem frames
with/for Burly .. there a top tube bent down to a mono-stay , and the seat tube pierced it for both F&R seat tubes..
