100 pcs.
100 sets would really set an attractive price point

The snowflake rotors have 10 buttons each, so that's 20 for a single bike.
Surely you can get 5 ppl to buy in.
I'm a tire kicker but if they were hard anodized, i probably would be far more inclined.
I might pull one of the chinesium rotors off and one off an old brembo to compare them. the ONLY downside of those chi rotors is the buttons, they are practically fixed mount.
