Fox CTD Remote 2014-2015

In the process of removing the Climb, Trail, Descend (CTD) remote level from Shelley's bike, I am fairly sure that I have worked out why it did not work very well. For the avoidance of doubt, this is for the remote used for Fox Evolution forks and rear shocks for model years around 2014 to 2015. That remote has long since been superseded.

Shelley did not use the remote and it was getting in the way on her handlebars. It would have been removed, even if it had worked reliably.

The otherwise good instructions for setting up the cables are not clear about some essential requirements.
The main bit, that needs better clarification, is that the CTD shock control knob and the forks topcap, need to be pre-loaded. By that, I mean that the knob needs to be rotated so that the cable is tightened up with the spring tension pulling on the cable.

On both the forks and the shock, this means the pale blue topcap and control knob have to be rotated nearly a quarter turn before the spring tension is felt. It is that tension that returns the remote lever to it's open position.

The above is easy, when you know how. Unfortunately, in my opinion, there is a design flaw with the remote operation when the remote is used for the dual setup of forks and rear shock. The through cable goes to the rear shock but the red rebound control, on the rear shock, tightens the blue CTD control knob so that the spring tension is reduced or completely locked out.

If too much rebound control is applied, deliberately or accidentally, the remote lever will never return to the open position, so both the rear shock and forks do not return to their open positions!

The photo from the instructions, shown above, makes it obvious where Fox expect the cables to go. I have not tried it but in my opinion, the remote might work better if the through cable, clamped with the grub screw, went to the front forks. The opposite of what is shown in that photo.
