Did Rolf make a 7 speed wheel?

Hi,
I spotted a bike in our company newsletter that the seller says has 7
speed
Shimano components with Rolf wheels. I've never run across these but am a
relatively new gearhead. Did Rolf make a 7 speed wheel? Can they be
converted to the 8/9 speed?

I don't think Rolf was making wheels back in the 7-speed days, but any of
the 8/9-speed wheels can be adapted to 7-speed use using a spacer (so my
guess is that it has standard 8/9-speed wheels).
