I am in the process of working out the gearing ratio for the Rohloff internal-hub, 700c 'dirt road' bike I am endeavoring to gather parts for. It's a 14-speed IGH, to be used with a single cog at the front.
Based on the 16t sprocket on the hub, and a 42t cog at the front, I used the Sheldon Brown Calculator (http://www.sheldonbrown.com/gears/internal.html) to come up with a range of gears from:
104 gear inches
to
19.8 gear inches
(My MTB has a range of 103 to 17.7 gear inches.)
This is the calculator for normal gears: http://www.sheldonbrown.com/gears/index.html
The 104<>198.8 range I would get using a 42t cog is the closest I could get to the ratio on my MTB, but I was wondering what the gear ratios are (in gear inches) of the TCC stalwarts' road bikes.
I cover similar terrain to you (but at a considerably slower pace), and I am curious about how my Rohloff equipped bike will compare to the gearing ration of your road bikes.
My addled brain gets befuddled when thinking about gears, and 'gear inches' is the only way I can conceptualize it.
