There was an article in Bicycling magazine sometime last year about
them.  Basically, they felt that these rings were most suitable for
the tourist, whose RPMs are not likely to exceed 80-90.  In this case,
the rings seem to decrease the strain on the knee.  Most racers, however,
found them ackward for spinning.
