What's your top speed?

Nudged 37.8 mph in the first floor of a pub courtesy of Rollapaluza. SS - not sure, probably only about 25-27 mph on the flat. Geared, top speed currently 52 mph (courtesy of the Cambrian Mountains).

On a regular run in Kent there are some great sections, just a little downhill gradient, where one can barrel along (geared) quite happily around 40 mph+ mark.

Sorry but that is quite slow on the rollers. A time of about 30seconds. Should be about 45 to 50.
