Present day choices if one wants a 40mm setback seatpost

Hello. On account of varied circumstances I am caught with my present bike for some time. It occurs to be measurement smaller than wanted, so I endure quite a bit whereas looking for a correct place I can comfortably use for a lot of hours (I am lengthy distance rider). I am now sure that my saddle must go manner again for this to occur. My present seatpost has setback of 25mm – and I would like a minimum of 40mm for it to be a strong answer.
I’ve regarded up comparable discussions, however options prompt there both discontinued way back and/or prohibitively costly (a whole bunch of US $).
I’ve solely discovered two viable options to this point:

  • Ergotec Vario Futura – which appears to supply as much as 50mm of setback; the one drawback is that it weights half a kilo, so ideally I would favor one thing less complicated with no adjustability and only a 40mm mounted setback
  • Some fishy Chinese language 40mm setback carbon seatposts underneath 30$ from Aliexpress – I am actually suspicious of those ones, they do not look strong in any respect

Anyone seen one thing that may very well be higher than these two these days?
