Also because the Vitesse has a nexus hub, do I get the "GP1 Rohloff®/Nexus® compatible"? Or is the one to get the "Gripshift® compatible"? Or just the regular?
The difference is that only the right hand grip is shortened on the Rohloff/Nexus-compatible version, whereas both right and left are shortened on the Gripshift-compatible version and neither are shortened on the regular version.
