Got some tasty new/used parts which I will be adding within the next week.

20" Racktime Foldit rack. Just ordered so don't even have this item yet, but I'm excited for it's arrival:



I'm fairly certain the Dahon and Tern rear racks would also fit this frame, but I decided on the Foldit rack instead. I read it's manufactured by Tubus. Seems this rack will be easier to remove from the bike and fold flat to pack into a suitcase (if that's even necessary).

Gyes ST15 leather seat and a set of 20 X 1.35 Primo Comet tires.



Vintage Suntour friction thumb shifters



Shimano Alivio rear derailleur



Wellgo platform pedals



Koolstop Mountain Pads



Now onto the question:

The "derailleur tube" on this bike is approx. 41mm (I measure roughly 1.615" using calipers), so would a clamp-on front derailleur hanger for the Dahon MU (like the Litepro that ThorUSA sells) work on this bike? I think it will. If it will work, I will probably add a compact double to this bike.
