It has become apparent in the last few months that the black and gold in the 340mm length shock has been discontinued. This has been replaced by a black and silver model in that length (pictured).
On multiple occasions I have been told that 340mm lengths units in black and gold would be delivered to me only to receive 320mm units. As a result, I am discontinuing sales of the black and gold units in this length. Obviously, this is a shame as it continued to be a popular color combination, but I have little control over the manufacture of the shocks.
The black and gold unit remains available in both the 375mm and 320mm length units.
