What is a versatile gearing range for a 3x9 drivetrain?
I'm asking just because i'm not sure where to start here.. I'm building up my first road-ish bike, and need to choose a cassette.
On the front, i have a 26-36-46 triple crank. I plan to use the bike as an 'all around' road bike. Mostly general road riding, not racing, perhaps some longer trips, and dirt road riding as well. I'm 27 and relatively fit.
I was looking at a 12-25 cassette, and plugged the numbers into Sheldon's gear calculator. Problem is, i don't know how to interpret the results, although my guess was that the mountain crank mated with the roadie cassette might give a good compromise gearing..
Attached is a screenshot of what i got. Does this gearing sound acceptable for my purposes?
For those averse to clicking, it ranges from 27.0 to 99.7 gear inches..
thanks!
