X-Lab RT9 Handlebar

The Branta integrated handlebar and stem is listed by X-LAB for the RT9. The bar and stem form a single cockpit, so choosing the right size means matching both the bar width and the listed cockpit length to your bike and riding position.

From a mechanic's perspective, start with the size markings or part number on your existing cockpit. Width affects how far apart your hands sit; cockpit length affects where the controls sit relative to you. With an integrated design, changing one dimension means choosing another complete cockpit size.
