Green Bike Store is a reseller of SuperTeam wheels (which you can buy on Amazon, Aliexpress, or direct on their website). Those ones are the unlabeled version of the Superteam from my understanding. I own 2 sets from SuperTeam wheels both 50mm deep and 25mm outer width with U shaped profile (not their 23mm V-shaped). One set in tubeless (when they first released it a 5 years back) and one clincher. Both sets has been fine for me and I am a 79kg rider. Their 50mm x 25mm are UCI approved if that matters

Only down side is the weight, they are heavier than the more modern 50mm deep carbon wheels but they are solid.
The "factory direct" ones I think you might not get to customize and just get the blank rims with standard build up. My custom ones all had to be shipped from China.
