Bars are available in a range of widths and when a choice is available the majority of cyclists choose a width that is equal to the width of their shoulder line (the distance between the shoulder joints). A wider bar opens the chest for better breathing and greater leverage whereas a narrower bar is more aerodynamic.
As a general rule you should consider the following size guide. It should be noted however that over 85% of experienced male cyclists choose bars with a width of 44cm and the majority of lady cyclists select a 38cm or 40cm bar.

We recommend the following stem lengths for Ribble Bikes (for a cyclist with an average reach).
