Get priceSep 27, 2015 · When the gear ratio goes over 3, the bike's acceleration increases but the top speed decreases. The inverse is true; when the gear ratio is below 3, the bike loses on the acceleration but gains top speed. The reason for this is very simple. Due to the increase in the front sprocket or reduction in the rear sprocket teeth, the ratio decreases.

Oct 22, 2013 · It's All About The Gearing Ratio. Your gearing ratio is, simply put, the ratio of teeth between the front and rear sprockets. This ratio determines how engine RPM is translated into wheel speed by the bike. Changing sprocket sizes, front or rear, will change this ratio, and therefore change the way your bike puts power to the ground.
Get priceMay 21, 2011 · When you've identified your driver gear and your driven gear, you can find the gear ratio exactly as before. In our example, we would find the gear ratio by dividing the thirty teeth of the driven gear by the seven teeth of our new driver. 30/7 .
Comparing gear ratios. The first method is to relate the gear ratio to wheel size by plying the gear ratio by the diameter of the wheel (Figure 1A). In the case of a road wheel, 27 inches can be used for simplicity (although the true diameter of a 700c rim fitted with a 23mm tyre is more like 26.3 inches).
