2021 FOX 34 Grip 2

[WC Bikes]

Hi Guys, would like to hear how everyone has setup their grip 2 dampers on the new fox 34.

I am 86kg and have started with the following setup:
PSI - 85psi ( for just over 20% sag )
LSR - 7 clicks from closed ( 2 clicks faster than fox base settings)
HSR - 4 clicks from closed ( same as fox base settings)
HSC - Fully open ( full anticlockwise )
LSC - 5 clicks from open

I ride a lot of fast rocky terrain around cape town and am finding fork qetting harsh when things get too fast. What would suggestions be from my above settings ?

harshness is often attributed to your rebound setting in particular high speed rebound and it could be that the shock is not getting time to come back up... too much rebound dampening since your hsc is fully open it is not that your settings is too hard and 20% sag seems plenty to also ensure the fork stay plush.

 

We often complain about shock or fork harshness but we tune out all the plushness with compression and rebound dampening.

so what I am saying is that fully open you are using as much of the travel as your pressure allow and that has to go hand in hand with a bit less rebound dampening to make sure the shock returns properly and does not bog down. I would speed up the rebound or alternatively run less sag at higher pressure.

I'd get the spring curve right first. The right amounf of ramp up via tokens and air pressure then tune in the required rebound damping.

 

Your air pressure seems a bit high. How many tokens are in the air chamber?

remember that as the fork travels up and down it gets hot which means the base pressure in the air spring is going to increase. Have you tried it with 25% sag and 30% sag? 20% seems awfully XC oriented for the plushness you seek?

Fox recommends 15% to 20% sag, so the OP is borderline soft as it is. Going softer will only make the problem worse by dropping the OP deep into the mid stroke and having very little left for when it is needed. Forks have a lot more surface area than shocks and do not build up heat and pressure like a shock would, so I do not think that is the cause of the harshness. Though maybe the old "zip tie down the inside of the seal" trick could release some pressure build up in the lowers. Pressure, tokens, rebound and compression (set in that order) should get the settings close. Failing that it may well be the fork has tight bushings which need to be resized
