Ashima Airotor 160mm installed on rear with Avid BB5 disc caliper

I installed the Ashima Airotor on the Crystalyte HS3540 motor last night. You can't really see the gold center portion very well and it looks a bit undersized for the job. I think I'm going to purchase a 200-203mm rotor to see if that fits the motor a bit better. I will need an adapter for the Avid BB5 so that it will fit with the larger rotor.

here is the Avid BB5 installed without the rotor on the motor.

Here's the rotor and Avid BB5 mounted.

I needed a larger rotor for the Crystalyte motor so I ordered these on eBay. The gold toned one is the 160mm. Sorry about the fuzzy picture. The silver toned one is the 180mm. They were the most striking rotors I have seen in a while. I'll post more photos when I get some time.
