The data sheet lists the number of ppr and rpm as :
Max RPM Resolutions
7500 RPM 2048, 1000, 800, 384 (plus res. from 15k and 30k RPM)
15000RPM 1024, 500, 400, 192 (plus res. from 30k RPM)
30000RPM 512, 250, 200, 96; 256,125, 100, 48
Although I have to wonder how those plastic hubs stand up to 30000 RPM.
