How do bike manufacturers measure frame size?
Most manufacturers now measure the frame from the centre of the crank axle, to the top of the seat tube. Most road bikes are measured in centimetres (cm), whereas mountain bikes are generally measured using inches (in). Kids’ bikes are measured by wheel size rather than frame size.
What are standard bike frame sizes?

What size is a 700c bike frame?
29″ / 700c (ISO 622 mm) The standard modern road bike wheel has an ISO diameter of 622 mm and is referred to as 700c (makes sense, right? /s).
What is the frame model of a bike?
Most bicycles have a frame number stamped into the metal under the bottom bracket. If it’s a carbon frame, the number will be etched into the surface or displayed on a sticker. Occasionally, the frame number will be on the inside of the chain stay or on the down tube or top tube.
What are the different components required for design of bicycle?
The main triangle consists of the top tube, the seat tube, and the down tube. The rear triangle consists of the seat tube, chain stays, and seat stays. The seat post and saddle fit on top of the seat tube. The bottom bracket holds the spindle and the cranks.
How are bicycle sizes measured?
Bicycles are measured by the length of the seat tube, from the centre of the bottom bracket to the seat tube. However, this might vary slightly from one manufacturer to another as some frames are measured from the middle of the top tube.
Is 29 inch the same as 700C?
29″ (ISO size 622) is actually the same rim diameter as 700C, although most 29″ tires will not fit 700C road rims because they’re too wide.
What does the C in 700C mean?
At one point in time, “700c” was a standard tire/rim size, where “c” indicated the bead seat diameter and “700” was the diameter, in millimeters, when the tire was installed and inflated. That “700c” tire size has a 622 millimeter bead seat diameter.
How do I know my bikes model?
The majority of serial numbers are located under the bottom bracket where the two pedal cranks meet. Turn your bike upside down and record the number. If there is no serial number near the cranks, you should check other common places including the front headset or rear stays.
What does Lowstep mean?
A step-through frame (also known as open frame, drop frame, or low-step frame) is a type of bicycle frame, often used for utility bicycles, with a low or absent top tube or cross-bar.
How is a bicycle design?
The most common design is the traditional diamond frame, which is formed by two triangles of tubing. The main triangle consists of the top tube, the seat tube, and the down tube. The rear triangle consists of the seat tube, chain stays, and seat stays. The seat post and saddle fit on top of the seat tube.
What frame size means?
The numbers beneath the frames reflect the SIZE MEASUREMENTS in millimeters (mm). THE FIRST NUMBER (ex.54) = the width of the lenses. THE SECOND NUMBER (ex.15) = the distance between the lenses. THE THIRD NUMBER (ex.140) = the length of the temple arm including the portion going behind the ear. The TOTAL WIDTH (ex.
How is frame width measured?
If you already have a pair of eyeglasses that fits you well, you’re ahead of the game. All you have to do is use a millimeter ruler to measure the frame width– the measurement of the entire front of the frame, from the point that sticks out farthest on the left, to the point that sticks out farthest on the right.
What does frame size refer to?
Frame size generally refers to frame height, the length of the seat tube from the bottom bracket (crank bearing) to the top tube.
What is the width of a cycle?
Any cycle has tree-width 2. The complete graph Kn has tree-width n − 1. A graph H is a minor of a graph G (H ≤m G) if H is obtained from G by removing vertices and edges and by contracting edges.
