We have been working of the new steering arm for the Borealis for a while. It will allow us to implement the central steering using the existing bearings on the trike. The way we had done this previously was to use much smaller bearings and a sleeve that clamped around them which also stuck up far enough so the mast pivot could also be fastened. Here is a picture of the first batch being made. The mast pivot and the steering arm are now one part. A much more elegant solution.
Along with the steering arm we have developed a carbon fiber mast and handlebar. The first one should be assembled in a couple of days. Once its together I'll post a couple of pictures.
