Rear shock removal

Too bad for him......

Thanks for that super fast shock removal tip. Easiest way yet!

Solid post dirtbird thanks. Did you fit a bladder to the Sachs ??

I run a FOX RC3 but why fit a bladder to a shock that already has a floating piston?

[Marty Moose]

Less drag, less leakage less friction

Marty, I think that especially regarding leakage its the opposite.
Most of the bladder shocks I have serviced are low on nitrogen pressure.
However I won't support 100% this as most of those shocks were serviced before by somebody else whose methods and skills are may be not known to me (or are questionable).

Still, I do believe that floating pistons are more reliable and require very little attention.

At the very least the geometry of the floating piston creates a very linear pressure rise.

Bladders are favored because they have no inherent friction to overcome, and perhaps more importantly (from a manufacturing point of view) the machining of the reservoir is almost non-existent and you don't have to pay for a piston, band, and o-ring. Gas does migrate across the rubber however.

What Steve said, plus the tuners that advocate the bladder likely do so with their own ease of service in mind. As far as less friction (a selling point), after all the math is done with the leverage ratio of the linkage and piston/shock shaft travel I would think the friction of that piston amounts to almost nothing at the rear wheel.

That was the one very cool thing about the KTM PDS. It was so easy to take off and put on...
