<p>A return spring biases a transfer element. A derailleur housing (5) has attachment points for the primary and secondary parallelogram arms, a clamp hinge, and a support extension (19) extending in a support direction along the bicycle frame beyond the region of clamp hinge of a tubular clamp. The support extension has at least one pivot point (8) for receiving a swing element and a pivot pin running parallel to the pivot point for receiving the transfer element. The clamp hinge is adapted to hinge and connect the tubular clamp to derailleur housing.</p> |
