When it comes to choosing the right gears for your mountain bike, it can be a bit challenging. To help you out, Anna Cipullo explains the maths behind gear ratio and range, to give you a better understanding of how the range and ratio differ between a 10-speed and 12-speed drivetrain. Now if you would like to do more research on this subject for yourself, including going into all of the variables such as wheel size, tyre size, crank length and more, we recommend heading to the Sheldon Brown Gear Calculator Website, which has got to be the top resource for working this kind of thing out.
