GEARING Questions

Just trying to get an idea what gearing outputs what speed in the real world as the charts don't seem to add-up..
Cheers
That is a million dollar question and depends on how much power someone puts through the pedals, and/or how fast they can pedal, there are still some people who can ride a 25mile TT under the hour on a 72" gear averaging around 118rpm Cheers

Look on here at the gear charts for the size of gear with Chainwheel/Sprocket combinations then below that a speed chart at various Gear size/pedal RPM combinations

or another useful site where you can type it in yourself.

24mph isn't that fast though unless we're talking hours on end...
