Speedub:
I can only find photographic evidence for a 210mm:

Smaller one is 210mm. Other one is a custom 231mm. Hope will make a custom rotor for a very reasonable fee (was $65 ea earlier in '08).
Not sure if they will make a custom carrier for Rohloff...but it wouldn't hurt to ask...they might even make it in lime green for you...
