2017 Fox Rhythm 34 started life @ 130mm and I dropped to 110mm when new. Decided to try a DSD Runt but was told minimum 120mm for proper functionality. Assembled w/ 120mm air shaft & DSD Runt. Inflated to recommended 2:1 pressures and the fork felt really firm - no sag. Hit the trails and ended up running a lot less pressure and still firm. Removed the Runt and went back to OE air cap & original pressures - still firm.

I have noticed I can compress the fork then hold the wheel down and pull up on the bars and extend the fork 7mm. Also w/ the air cap off if I compress the fork it returns up about 3/4 of the way. Air in lowers? Thanks.

Air in lowers? Thanks.

Seems like an easy thing to diagnose.

Flip the fork, break the shafts free, then reattach the foot nuts.

Did your air shaft slip in the vise when you switched it? Or did you replace the spring with an entire assembly?
