Can a dual position rock shox fork (Pike/Revelation) be lowered?

[mrx78u]

Hi RBers,

Was wondering is a dual position rock shox fork can be lowered, eg: 160mm dual position pike to 150mm in it's extended position.

Cheers.

I know my 180mm dual position air LYRICS can be and have been lowered to 160mm.

Yeh, just flick the switch on the top there and they should lower :bounce:

Pretty sure recent Rockshox air-sprung forks cannot be lowered from their original travel (or positions in the case of dual position adjust) without changing the air shaft itself to the travel you desire (140mm,150mm,130mm etc).

In the old days it was a matter of putting spacers on the shaft. Now they have a new air spring system in which a dimple is recessed into the stanchion, which regulates the pressure in the negative spring as the fork cycles. If you use spacers on the same travel air spring, it will bugger up this system and the fork won't ride properly (so I'm told)

EDIT: not sure if this hold true on the boxxers/totems/lyriks. Pretty sure it only applied to forks that used to have dual air springs like Sid/Reba/Revelation etc...

I faintly remember something about 'cutting' your air shaft somewhere. I dont think it will be long before custom ones are on offer though...

there seem to be a whole lot of air shaft changing going on in this thread...

yeppp, has been done, think NoSkidMarks was the first on here to do it.... however im pretty sure it only applies to solo airs.....

and theres only a certain amount you can cut... as the thread on it runs out and you wont be able screw the bolt back on.

These custom ones you are talking about..... You can buy from sram and they have a part number too!!! This is for solo air only and takes about 15minutes to install
For eg: 11.4018.022.005 revelation 100mm air shaft.

Get part number for the air shaft in the travel length/wheel size you want, go to LBS, get order done, install air shaft, done Check p47 for the pike. Dual position airs have 4 possible air shafts.
