It is quite interesting to use Bike Calculator. Set the power to 0 watts and use negative numbers for the gradient. On the tops, and leaving everything else alone (11 stone rider, 20 pound bike, no wind etc.) a downhill slope of 6.5% yields a descending speed of about 30 mph.Is there any theoretical basis to the "around 30mph" limit, or are you summarising your experience?
I think that is about right. There are plenty of those hills round here and that is about the speed that I do in casual descent mode. If I get on the drops, pedal until I spin out and go aero then I get to 40+ mph.
