Gear Calculator by
Sheldon "Gain Ratio" Brown
The first preset shows my current road bike setup (compact double standard madone front ring; custom SRAM larger 10-gear rear cassette (ordered stock part that my bike store simply replaced the stock cassette with!) selected and charted below. You can click between my old bike (triple) and new bike (double) to see how similar my old and new bike ranges are. Yay -- a double that can climb so close to a triple!)
