The [[Bicycle handlebar|handlebars]] connect to the [[Stem (bike)|stem]] that connects to the fork that connects to the front wheel, and the whole assembly connects to the bike and rotates about the steering axis via the [[Headset (bicycle part)|headset]] bearings. Three styles of handlebar are common. ''Upright handlebars'', the norm in Europe and elsewhere until the 1970s, curve gently back toward the rider, offering a natural grip and comfortable upright position. ''Drop handlebars'' "drop" as they curve forward and down, offering the cyclist best braking power from a more aerodynamic "crouched" position, as well as more upright positions in which the hands grip the brake lever mounts, the forward curves, or the upper flat sections for increasingly upright postures. Mountain bikes generally feature a 'straight handlebar' or 'riser bar' with varying degrees of sweep backward and centimeters rise upwards, as well as wider widths which can provide better handling due to increased leverage against the wheel.
