True, mine does as well, but other brands like Fox and Rockshox use them as positive air chamber spacers. I think they are the only brand out there that allows for customization of the negative air spring.
Thanks for posting that. I'm 4 days/rides in with my DH38s and having a nightmare with braking bumps and square edge hits (high speed compression sort of stuff) I just can't get them tolerable over high speed chatter. Sending them in for a tune so will ask them to remove the spacer. My RXF38s are tuned and feel amazing.
@@NICADV It's weird because once you disassemble the ttx cartridge, then to assemble it you must have the information of when to put oil. Thank you so much for replying, I'll keep looking
