A bicycle stern has a steering tube clamp with a bore for receiving a steer tube and a pair of parallel spaced arms each having an elongate slot at a distal end. An extension has a proximal end, receivable between the clamp arms, and a bore extending transversely through its proximal end. A pin, extends through the elongate slot in each arm and through the bore in the extension for securing the extension to the steering rube clamp. The pin slots and bore are in non-rotational engagement to prevent rotation of the extension relative to the clamp, and the pin is selectively movable longitudinally within the slots for adjusting reach of the extension. |
