First question

The Blackwell 100 and the Planet X 101 (both tubs), same carbon rim? Hubs, different?
Same “angel hair” “marble” pattern on the wheel? How about “inner nose” shape. Basically what is the difference between these wheels? Only thing i can see is hub, and perhaps spokes, and a 50g weight difference.
More questions to follow based on the answers.

They are admitted to be different wheels, I can’t tell you any more than that.

Here John and Planet X kind of go back and forth…

I have not seen either in person but I definately understand the need for a refined nose, and if the PX is indeed a V shape I would opt for the BR.
