Weber ER coupling – cargo trailer coupling up to 80 kg

To attach a trailer with a WEBER drawbar connection to your bike, you need a suitable WEBER coupling. It is mounted to the rear wheel axle using the patented polygon mounting system, preventing rotation. Please ensure you have the correct version for your bike.

The ER coupling is mounted on bikes with adjustable Rohloff dropouts.

Thicker special polygons are rarely required for quick-release axles and hub gears, or the X12 replacement thru-axle.
