Bottom Bracket Drop
Bottom bracket drop is the vertical distance between the center of the bottom bracket and a horizontal line connecting the front and rear axles.

Bottom Bracket Height
Bottom bracket height is the vertical distance from the ground to the center of the bottom bracket.

Crank Length
Crank length is the distance from the center of the bottom bracket to the center of the pedal axle.

Fork Rake
Fork rake is the perpendicular distance from the steering axis to the center of the front hub.

Front Center
Front center is the horizontal distance from the center of the bottom bracket to the center of the front axle.

Handlebar Drop
Handlebar drop is the vertical distance between the top of the handlebar and the lowest point of the drops on a drop bar.
READ RECORD → - REF: #008-D TS: 26.04.26 definition geometry
Handlebar Reach
Handlebar reach is the horizontal distance between the center of the handlebar clamp and the furthest forward point of the bar.
READ RECORD → - REF: #009-D TS: 26.04.26 definition geometry
Handlebar Width
Handlebar width is the horizontal width of the handlebars measured from end to end at the grips or hoods.

Head Tube Angle
The angle of the head tube in relation to the ground.
READ RECORD → - REF: #011-D TS: 26.04.26 definition geometry
Head Tube Length
Head tube length is the distance from the bottom of the head tube to the top of the head tube, measured along the tube. It accommodates the headset bearings and supports the fork's steerer tube.
READ RECORD → - REF: #012-D TS: 26.04.26 definition geometry
Reach
Reach is the horizontal distance between the center of the bottom bracket and the center of the top of the head tube. It is one of the two key sizing measurements (with stack) used to describe a frame's fit independent of seat tube length.

Rear Center
Rear center is the horizontal distance from the center of the bottom bracket to the center of the rear axle.
READ RECORD → - REF: #014-D TS: 26.04.26 definition geometry
Saddle Height
Saddle height is the distance from the center of the bottom bracket to the top of the saddle measured along the seat tube axis.
READ RECORD → - REF: #015-D TS: 26.04.26 definition geometry
Saddle Setback
Saddle setback is the horizontal distance behind the bottom bracket where the saddle's center rail clamp sits.
READ RECORD → - REF: #016-D TS: 26.04.27 definition geometry
Seat Post Length
Seat post length is the total length of the seatpost from the bottom of the insertion point to the top where the saddle clamp sits.
READ RECORD → - REF: #017-D TS: 26.04.26 definition geometry
Seat Tube Angle
Angle of the seat tube in relation to the ground.
READ RECORD → - REF: #018-D TS: 26.04.26 definition geometry
Seat Tube Length
Seat tube length is the distance from the center of the bottom bracket to the top of the seat tube where the seatpost is inserted. It was historically used as the primary frame-size descriptor.
READ RECORD → - REF: #019-D TS: 26.04.26 definition geometry
Stack
Stack is the vertical distance between the center of the bottom bracket and the center of the top of the head tube. Together with reach, it is the standard frame-only measurement used to describe a bike's fit.

Standover Height
Standover height is the vertical distance from the ground to the top of the top tube at the point where a rider would straddle the frame.
READ RECORD → - REF: #021-D TS: 26.04.26 definition geometry
Steerer Tube Length
Steerer tube length is the length of the fork's steerer tube that passes through the head tube and supports the stem.
READ RECORD → - REF: #022-D TS: 26.04.26 definition geometry
Stem Length
Stem length is the distance from the center of the steerer tube clamp to the center of the handlebar clamp on the stem.
READ RECORD → - REF: #023-D TS: 26.04.26 definition geometry
Top Tube Length
Top tube length is the distance from the center of the head tube to the center of the seat tube measured along the top tube. The effective top tube is the same measurement projected horizontally, regardless of whether the actual top tube slopes.

Trail
Trail is the horizontal distance between where the steering axis intersects the ground and the contact patch of the front tire.

Wheelbase
The horizontal distance between the front and rear axles.
