How do you measure a drop bar on a road bike?

The bar’s drop is measured from the center of the flat top section to the center of the bar at the deepest point of the drop. A shallow drop (125mm or less) means your body position changes less drastically from hood to drop than it would with a deep drop of 130mm or more.

How is road bike drop measured?

Drop: The vertical distance from the center of the bar top to the center of the deepest part of the bend. A drop of 125mm or less is considered shallow; 125-128mm is medium; more than that is deep. Drops: Straight portion of the bar that extends back toward the rider.

How do I know what size my handlebars are?

Just wrap around the bar at the point you want to attach the Oi to get the circumference size and then divide by pi (…. mmm) to get your diameter e.g. 99.9mm / = 31.8mm. If you have no tape, then use a piece of paper (or string).

How much do handlebars drop?

While some pros run very extreme handlebar drop; the typical range for road bikes is 10–15cm measured from a horizontal line at the saddle height dropped down to the handlebar.
