More often than not track cyclist simply switch out their sprint bars for aero bars (or vis versa) without taking into account the height and fore-aft of their seat position. This is a big mistake! I guarantee that there will be a significant change is saddle height as well as fore-aft when switching bars. To get the very most out of this switch the rider must make the saddle changes that need to be made as well as the front end changes. These are two completely different fits, but good news! These two separate fits will most often work on the same bike.
