Doggy Tourer Webber B Coupling System

Clutch B, BO

Bicycles with a trailer need a solid stand, especially when loading or unloading. The coupling B was developed by Weber for this purpose.
The B-coupling is the most commonly used rear-mounted clutch with integrated stand for bicycles with a wheel size of 26" and 28".
The BO coupling is the special version of the B coupling without the integrated side stand.

Featuring secure tensioning tape mounting, this product is perfect for everyday life and touring. The sturdy, adjustable stand has an extra-wide base for stable support on any type of ground. The clamping straps can accommodate pipes with diameters ranging from 12 to max 25 mm.
