Some manufacturers measure this from the center of the bottom bracket to the top of the seat tube. Others may take it from the center of the bottom bracket to the center of the top tube. Generally, this measurement indicates frame size. A 17 inch bike will have a 17 inch seat tube and a 56cm bike will have a 56cm seat tube.
B: Effective Top Tube
The length the top tube would measure if it ran horizontally from the top of the head tube to the seat post. Arguably the most important frame measurement for determining a proper bike fit. It tells you how stretched out or upright you will be while on the bike. This can be “adjusted” slightly with different handlebar types and stem lengths.
Stack is the vertical distance from the center of the bottom bracket to the top of the headtubes vertical plane. Stack and reach when looked at together, can accurately identify how “long” a bike frame is and offer a clearer picture of how two important contact points, pedals and handlebars, relate to each other.

E: BB Height
Bottom Bracket Height - Distance from the ground to the center of the bottom bracket. Bikes ridden offroad benefit from the extra clearance offered by a taller bottom bracket height.
F: BB Drop
The measurement from a bicycle’s wheel center, to the center of the bottom bracket. A deep bottom bracket drop puts the rider's weight at a lower center of gravity and a feeling of being “in” the bike, rather than on top of it, as some tall bottom brackets can provide.
G: Head Tube Length
The length of the head tube from bottom to top. Shorter top tubes are generally stiffer than longer ones, but longer head tubes are usually necessary for larger bike frames.
H: Head Tube Angle
Head tube angles can range from about 66 degrees to 74 degrees. Generally, a bike with a steeper head tube angle will steer more sharply while a bike with a slacker head tube angle will be more inclined to travel in a straight line.
I: Seat Tube Angle
These can range from around 70 to 75 degrees. A steeper angle moves the saddle forward of the rear wheel and bottom bracket. A shallower angle moves it back. Steep is fine for racers and aggressive riding positions but not so good for a more relaxed style. Saddle position and seatposts can be used to “adjust” this dimension.
J: Standover Height
Distance from the ground to the top of the top tube.
K: Chainstay Length
Distance from the center of the bottom bracket to the center of the rear axle. Longer chainstays contribute to a more comfortable ride and increased climbing traction. Shorter chainstay improve cornering ability and power transfer.
Wheelbase is the distance between the front and rear wheel axles. Shorter wheelbases can make the bike feel more lively while a longer wheel base improves stability and comfort.
