Dahon Boardwalk Ultegra Di2

From the humble Dahon Boardwalk D7 to the current fully-modified Dahon Boardwalk Ultegra Di2, there has been a lot of changes! Along they way, the speeds were changed from 7 to 8, 8 to 9, and recently a front derailleur was added, doubling the number of speeds to 18. And just to top it off, the drivetrain has again been upgraded to an electronic Shimano 2X10 speeds, making the current bike a 20 speed folding bike with Ultegra Di2!

From flat handlebars to bullhorn bars, and then to dropbars, the changes have been well documented. The wheelset has been changed from the stock Dahon D7 wheels, to Kinetix Comp, to PZ Racing and currently Wheelsport wheels!

There are many many more components that were upgraded, read all about it and enjoy all the pictures at the links below!
