Mountain bikers should also gear for the hardest climbs. Mountain bikes typically have 9-11 cogs in the back and 1-3 chainrings in front, indicated by 1x9, 1x10, 2x10, 1x11, etc. Mountain bikes have traditionally come with two or three chainrings to provide a variety of easy gears for climbing. However, mountain bikes with single chainrings are now very popular.
