Berthoud Decaleur - Vertical 121 longer extension

Berthoud Decaleur - Vertical 121 longer extension extension. This model places the bag farther forward than the 91 shorter version. If you have a stem where the stem binder bolt is vertical, then this is the Berthoud Decaleur to use. The supplied bolt may or may not work, depending on what stem you have, so you may need to visit your local hardware store if necessary.
