Who makes TT/Tri Basebars that can be flipped for a positive rise?

[teichs42]

Trying to create a list of what companies offer a tt/tri basebar with a flippable positive rise.

Winow makes one, but they have previously told me that wouldn't sell just the bar. This one seems to be available from TanTan/Seraph, but not sure if they'll sell individually.

I'm hoping to buy the Velobuild TT023 but would like to have a basebar with a rise to offset some of the lower stack height.
