Dahon Dash Altena

This is a thread dedicated to my Dahon Dash Altena build, and to Altenas of other members.

It all started with just the frame and fork...




Add and mix:
▪ Shimano 105 5800 groupset
▪ Wheelsport Super 451 wheels
▪ VO Porteur handlebar
▪ VO stem
▪ Ritchey Logic cork handlebar tape
▪ Crank Brothers Candy
▪ Cardiff Cornwall saddle
and the result was this:





L frame
Top tube: 55.5cm
Seat tube: 51cm
Chain stay: 42cm
Seat stay: 54cm
Head tube angle: 73
Bottom bracket height (on 23mm tires): 28cm
Wheelbase: 103cm

25-99 gear-inches

[the other, original thread will no longer be updated]

Beautiful Bike! Are the brake levers comfortable with that bar?

Thanks,
Yan

This came out beautifully. I luv the look of it,...a city classic. Around my area I'd be riding the king of folders if I built one of these babies up. Fantastic ride!!!

Really nice build! Good geometry as well. The folding frame makes a good case for a travel bike.

● Installed a light, polished kick-stand

Really nice build. How did you get a frameset? I'm in the USA, and the Altena's are not available here. I thought about ordering one off Rakuten or Amazon Japan, but wasn't sure how the shipping would work, import taxes (Rakuten & Amazon Japan both required a 3rd party shipper)--I took a pass. Too many "moving parts" to get a bike that should have been sold here in the USA. If you have any suggestions for how to get the Altena or just the frame, let me know.
Same situation applies to Hasa . . . they seem to make a lot of nice stuff, but their ti folder is not available in USA. Jurien helped me buy a TI Swift from Titan Product in China (check out the Titanium Swift thread--a picture of my bike is on one of the last pages).

Thanks. I struck a deal with the bike shop. Simple as that. They can be had in Bangkok too.



My only suggestion for getting one is to take a vacation in Thailand, and take one back home with you.

Thanks.

Really can't say that I have ever heard of Maxxis Torch before.
Its good to have one more option for wide 451 tires when I use my bikes for trips that may involve some light trails.
