A high-quality metal lock is firmly integrated into the red button and reliably secures the release mechanism. With this security, the shopping basket can also be left on the bike. Even with heavy accessories, the adapter remains absolutely twist-proof and securely attached to the handlebars thanks to the patented cable tensioning system. The adapter can be adjusted to different conditions on the bike. Various spacers, mounting bases, and clamp sizes allow for installation on almost all bikes. For Ø 22-26 mm.
