Compare to this page from their 2023-2024 catalog. Several differences--no logos, no polish finish, a different mix of existing rings, and available in one more size. Kind of lower spec, similar function.
They also have a five-arm crank with the same pattern of similarities.
Test fit the other night w/ an olde Shimano 600 bb. 113mm spindle, 130mm old rear looks good. The crank bolts had the black snap-on dust caps w/ the brass autex-style rings were included separately. They look good though.
I have a pair of those VeloOrange TA-clone cranks, and the arms are dead straight. Makes it a pain to set up a front derailer such that it doesn't rub the backside of the DS arm. That's with an olde flat outer plate fd. These cranks flare out subtly, it's a huge qol improvement.
The other thing with those VO cranks--the DS crank shipped assembled, but I could perceive relative movement, so I tightened the chainring bolts... and deformed half of them. 4mm hex on both sides, some oddball size. Quite soft, looks like some kind of stainless.
The kicker is these new cranks cost less.
Someone else (BikeForums? RBW Owners Bunch?) speculated that these aren't sold in the US, because a German in Seattle who sells an incompatible but aesthetically similar crank is... very aggressive, in a legal sense.
