I had a ’13 CTD Pushed…. I am 95Kg in my kit.
Before Pushing I tried the volume spacers, they have an effect but never came close to compensating for the inherent flaws.
The Push tune had a transforming effect, I asked for sensitivity around the sag point to give good traction over wet roots of which we have plenty, control through the mid stroke and a moderately firm ramp up at the end, I like to use full travel but I like it controlled.
I wanted the suspension to remain active when climbing as grip is important to me over outright efficiently.
I got all of the above, performance is now very good.
It is not as good as the CCDBAcs I have on my bigger bike which is excellent.
I also had ’13 Fox 34 forks that were quite frankly dangerous…. couldn’t trust them at all, bit the bullet and had the full Push on them, CTD gone and high low compression adjustment back in plus tokens etc…. wow… fantastic fork now, so good that the frame is going and the shock is going on my sons bike and the fork has just had a HT frame bought for it just to give it a home as it is now so good.
Regarding CCDB Inline there was an issue re weight of rider, not sure if that is sorted now.
