How to Determine Mountain Bike Size?

Frame Size: Frame Size refers to the length of the seat tube. Most often it is measured from the base to the top (Center-to-top (C-T) frame size). Note that some bike manufacturers (most often European) use a Center-to-center (C-C) frame size reference. Then the lenght of the seat tube is measured from crank center and up to center where seat tube meets the top tube. NOTE: In the size chart below, Center-to-top frame size is used!
