Drop Handlebar A drop handlebar is one in which the middle of the bar is the highest point, or nearly.
Dropout A type of forkend that allows the rear wheel to be removed without derailing the chain first. Rear dropouts come in two styles: Dropout spacing varies among different styles of bicycles. See my Home Made Drop Bolts article. For longer rides, the ability to change positions is very desirable. These grooves are totally unnecessary. Vertical dropouts have a vertical notch for the axle to go up into, and the axle's position is not adjustable.
Drops The lower parts of a drop handlebar, the area below the brake levers. The draisine walking enhancer, permitting the user to cover more ground dynamo slot each stride, and to coast down hills.

The drivetrain area of a frame consists of those parts of the frame that are directly stressed by the drive train parts, specifically the chainstaysdown tubeand seat tube.
This dimension is often preferred to the bottom-bracket height dimension, because it is the same whatever tires are installed on the bicycle.
A bicycle with a shorter drop higher bottom bracket will be less at risk of striking a pedal on the ground during high-speed cornering or obstacle jumping. Driver The part of an internal-geared hub or coaster brake that the sprocket attaches to, either by threads or splines. Opinions and value judgments are our own, unless otherwise noted -- Sheldon d.
A few single-speed or internal-hub gear bikes use vertical dropouts with an eccentric dynamo slot bracket to permit chain tension adjustment. Vertical dropouts are generally intended for use with derailer gearingand do not permit any adjustment of the position of the rear wheel, so there's no way to regulate chain tension if you don't have a derailer or pulley type dynamo slot tensioner.
