Not really. The easy options to save weight are already done. Maybe another 100 g or even slightly more with a new seat even lighter than the current one. Maybe a few grams by using ultra light pedals, and maybe a few grams by more lightweight and thinner steering rods. The remaining option with the largest potential - replacing the central aluminum frame by a stiffer and less heavy one from carbon fibre is expensive and fully out of my reach. And pretty ridiculous for that vehicle except to replace a broken frame (which hopefully will never happen).
But anyway - there is potential in a significantly more leightweight tailbox, and even in one with better aerodynamic performance. But before doing something like that i need to
a) learn and
b) improve the flow in the front parts of the velomobile.
c) retire (which i will at the end of the year)
Overall the performance of that velomobile has already improved quite a lot, and i am acutually quite satisfied by that.
