Hated the Float CTD Evo that came on my Bantam. Took it apart, this is what I found:
![]()
Damper assembled, pulled from damper body. In this picture, the damper would be in descend mode.
![]()
No high speed rebound, just a plunger with a .5mm thick shim/washer that covers the HSC ports from the bottom. This is what the CTD lever controls(controls how close to the piston face the shim is)
![]()
Piston removed. All shims and check valve installed still.
![]()
Piston/check valve pulled apart. LSC shim stack would be the larger shims only and main ports along the outside of the piston flow to them. These are the ports the CTD valve covers. The smaller shims are the HSC shims They sit under the LSC shims, so both shim stacks are part of the HSC shim stack.. When the LSC ports are covers, the HSC ports are still open allowing the oil to flow, but both stacks need to flex to allow Flow.
![]()
Close up of the shim side of the piston. HSC shims fit down in the inner circle. LSC shims go on top and cover the rest of the piton. Like I said earlier, the shim stacks run in series, so HSC oil flow must flow through the LSC stack as well.
![]()
Bottom of the piston. The ports along the outside are what the CTD washer covers. The ports on the inside are recessed to allow oil flow to them when the LSC ports are covered. This is what gives the lock out its blow off.
Overall, I'm not surprised that the shock performs so poorly. No HSR circuit is ridiculous for rear shock, especially one from Fox. The in series shim stacks are also a questionable at best design. I would say I expect better from fox, Unfortunately I don't.
