The Vector X27h never made it to the US. Please see the link above for the Verge X30.
If you’re used to using your bike’s gearing to get maximum efficiency when pedaling the Dahon Vector X27h is perfect for you. With a 27 speed SRAM Dual Drive drive train, you can easily power up hills and and speed down flats. The Vector X27 also makes a great commuter because you can use the internal hub gear to shift without pedaling and use the derailleur for more finite shifts while riding.
