A growing number of bikes use an internal-gear hub, which typically eliminates the need for derailleurs, cassettes and multiple chainrings. While the range of gears on hubs may be limited, they have the advantage of needing less maintenance, being simpler to use and have the ability to shift...

Some gravel bikes come with a 2x drivetrain, which provides a broader range of high and low gears for climbing and descending. This comes at the expense of additional weight and complication in gear choice. When choosing a gravel bike, it's important to consider the type of terrain you’ll...
