New, redesigned Tern Luggage Truss
The new design allows for routing cables through the truss itself, allowing a cleaner look and no inteference with attached luggage. Load limit remains 7kg. $34 in my locality. Includes mouting bolts, a velcro strap (purpose unspecified), and two keys.

Out of curiosity, on Dahon/Tern bikes, why aren't cables close to the stem like on the Brompton, which would make it possible to have a compact carrier block that can carry more weight (10kg vs. 7kg) and be more stable (because of the truss, bags wobble more on a Dahon/Tern) ?

I like your idea, but I think it's because the angle of the B's levers are close to vertical so the cables are too. Other folding bike ergonomics and regular mtb levers force the lower degree cable angle. The Tern above has very flat levers, weird. I prefer my levers closer to 45 degrees but the cables definitely stick out more than a regular B.
I think the new truss looks sweet.

The result is that the required cable slack ends up at yhe front of the bike as it should not be at the rear with chains and cranks all turning fast enough.
I find that I can flatten yhe slack along the Handlebar post. Perhaps shortening the cable tubes coukd work on externally routed cables ala Brompton.
Ine if the reasons a Speed Uno is so popular is that it is nearly clean of cables.

In detail you can see it on this page https://www.velowerk.ch/werx.html (search for the term "cablerouting"). The text seems to be available in German only. He states there as well that Tern might use this routing as a standard in future.
You can find a picture of the cable routing on his homepage: willkommen im velowerk! (scroll down almost to the bottom, green bike on the left side). As he seems to be a bit anal about copyright I won't embed the picture here.

A simple solution would be to add V brake elbows at the levers so the cables go down.
I suppose a more elaborate solution would be a lever with a roller wheel that can adjust its angle instead of a straight cable pull like current levers. For a minute I thought about developing this idea but with hydraulic brakes being so cheap now, I think the days of cable brakes is fading.

Brompton has brake levers made for them , designed to aim the cable downward.. from the lever
Tern uses levers from general parts sources around them, made for use by all kinds of TW based bike companies..

...Might come in handy with the FSIR, though.

Will soon test the limiting factors...
...for i (re-)purchased the truss with a tour in mind. Stay tuned for real-world, field testing...

Hi Abu.
Sorry for not being specific. It is the lower part of the red plastic part where it latches onto the luggage. Image here.
Busted the KLICKfix handlebar adapter 2nd time, anyone find a solution to this?

I've seen that breakage reported elsewhere too. Odd because that part should not see a lot of stress. This is what that part looks like on the new item:
Btw, Gen II is 35g lighter than Gen I.

I just checked another Klickfix caddy of mine, and noticed that the region of the part in question has a pretuberance, that is, it is thicker. I no es longer have my Tern Luggage Truss v.1 to compare, regrettably.
