Duragrouch , nicely done! I own a similar Dahon that I've modified several different times. It is currently set-up with drop bars and Shimano 105 gear. But my plan after the new year for a redux is to use these items I just ordered from Velo Orange.

I also ordered matching brake cables.

The microSHIFT Advent set will be paired with my SRAM DualDrive 3-speed IGH rear wheel and a dynamo front. I plan to keep it as a "Zero Bike" at my daughter's home in Knoxville and use it for rides in the Smokies foothills.
