Body measurement for bike. You no doubt already know your height but the inseam measurement you need for bike sizing is not the same as the one you use when buying jeans which will be at least two inches shorter than your actual inside leg length. To measure your bikes frame size take a measuring tape and place the tape in the center bolt of your bikes cranks. Stand with your feet 6 inches apart then measure from the inside of your foot up to your crotch where your leg meets your waist. To find inseam length for cycle fitting purposes remove your shoes and any baggy trousers. Itll make the whole process easier and youll be set up for success right from the beginning. We need 8 core pieces of information in order to calculate your optimum frame size and initial position.
Ideally youll know your bike size before you buy. To calculate your bike frame size take your inseam in centimeters and multiply it by 0575 for mountain bikes 0665 for road bikes and 0645 for trekking bikes. When you reach the end of the seat tube you have your frame size. If it is just the frame this will be the center point in the bottom bracket shell. Now run the measuring tape up your seat tube. Think of the seam on the inside of a pair of jeans.
If you need to convert your measurements to inches divide them by 254. Listen to your body. You can have two bikes with the same frame size but differing stand over height.
