The largest sprocket on a road bike cassette is generally smaller than those on mountain bikes providing smaller jumps between gears. Road bike cassettes will have smaller sprockets with a smaller jump between the teeth sizes when compared to mountain bike cassettes. For example a 53 28t crankset combined with a 7 speed 11 19t cassette will provide the same number of discrete ratios as a standard crankset paired with an 11 speed 11 27t cassette as shown in. Attempting to push pro level gearing can be a recipe for disaster if your bike.
