Front Derailleur Braze-On Adapter Shimano SM-AD11 31.8mm
The Shimano SM-AD11 is a high-quality braze-on adapter designed to mount a braze-on front derailleur to a frame that does not have a built-in braze-on tab. It is an ideal solution for frames that require a clamp-style mounting option.
The adapter fits around a 31.8 mm seat tube diameter and provides a secure and stable base for braze-on type front derailleurs. Precise fit and Shimano quality ensure reliable shifting performance and straightforward installation on road, hybrid and mountain bikes.
Lightweight yet durable, the construction adds minimal weight while maintaining a clean look on the frame. The Shimano SM-AD11 is a practical and professional solution for riders who want to use a braze-on front derailleur without a dedicated frame mount.
