Thanks, Udi!!No you can't install the stack in the pike, but basically - the speedstack is only detrimental to performance. A stock pike damper achieves the correct shape/range of compression damper curves because it has the compression adjuster and floodgate (nothing more). This thread was about bringing the boxxer team/wc to that state (removing speedstack) as well as the race (adding internal floodgate control).
As for the rebound piston, I'm not sure... I have both forks but can't be stuffed taking the pike rebound damper out to compare. From pics I've seen in the past though, I think they may be a little different - but don't quote me on that.
That cuts it for me.
