For Road and Triathlon bikes it’s more common that the frame size is given in cm however occasionally the XXS to XXL notation is used so I have listed both.
For mountain bikes the XXS to XXL is more or less the standard now however some manufactures use inches as well but usually in addition.
Some manufacturers also list bike size my your inseam length, however unless your have unusually short or long legs the height reflects your inseam.
