ER 1400 SPLINE® 21

Nowadays road riding is much more than riding on a road. Gravel, bad choppy roads, fenders, lights, disc brakes and even racks have broadened our horizon. The ER 1400 SPLINE 21 is your premium aluminum choice if you continued reading after the word rack. Coming with a 20 mm wide, super light and resilient rim as well as a hub based on the well-proven 240s, it is just what you need when your rides lead into the unknown but there are still the occasional bragging rights to be defended.
