    Have the same fork. Run 70psi. weight 80kg. Use fully open mode 80% of time with 4 clicks of rebound.
    The fox website pressures are way out. I took a token out for similar reasons as your describing.

    I have the 150mm version and was surprised how low I had to set my pressure to get full travel compared to my old rockshox.

    Good info, thanks. I had the rebound 7 from slowest,5 from fastest. Will let a little more air out and try it at 65/70, cheers.

    The token made a big(psychological?) difference and was super easy to do. I’d start with lower pressures first. Great fork, set up right mine has great small bump, even at speed and is great through the mid stroke. My o ring tells me I bottom out a fair bit but it ramps up so nicely towards the end that I don’t think Ive ever noticed.

    18mm sag seems very little for a 120 fork. 24-30mm would be 20-25%.

    Fox recommend 15% 18mm for “firm” and 20% 24mm for “plush” I have runs with 20% and used the middle damping setting adjusting to full open for downhills but that required too much concentration and I was getting the best small bump performance ever with 15% sag so stuck with that.

    18mm/15% is fox ‘firm’ recommended sag setting, 24mm/20% ‘plush’.

    I’ve got some 2016 fit4 32’s, and im running them at around 18mm, i found them divey on the plush setting. Different fork i know, maybe i should play around with tokens…but i always like to leave some travel for when i inevitably over cook something.

    :too slow 😆

    Pahoehoe – yeah, that’s what I was following too, but given advice, and your pressures at a similar weight, I’ll drop mine to 70 and try tomorrow, then maybe 65. I also tend to pop it fully open on decent descents. My 12.5 stone is in riding kit…

    Have one of these on my Anthem, it’s this one :

    Fork: Fox 34 Float Performance Elite, 120mm Travel, FIT4 Damper, 15×100 KaBolt, Tapered

    Works well but struggling to use more than 90-100mm of its 120mm travel. I am 12.5 stone and had it set up initially at 85 psi giving around 15-18mm of sag. Dropped it the other day to 75 and seems a bit better. Curious as to other rider weights/air pressures with same fork.

    settled on 60 psi and it seems ideal now, getting almost all the travel most rides, cheers all.

    Like you all I had to set the pressures lower on both sets compared to suggested, to get the correct sag (mine are 150mm Travel 34’s).

    Thinking of taking a token out on both sets (factory setting is with 2 i believe) as we never get much into the travel due to rider weights, except for one day at BPW where we were up to 140mm-ish.

    interesting, wonder what target rider weight they use in factory when setting up…

    I have the same issue. Might be worth checking the volume of oil in the shock. Mine came from the factory with 27ml in. They’re supposed to come with 5ml. Even after that I run them at 95psi (I weigh a huge 105kg) and rarely get near full travel (admittedly, I’m not that ‘gnar’ a rider). I’ve tried taking a token out and didn’t feel much difference. It’s the mid-stroke I’d like a bit more support on. If I run at lower pressures, I get closer to full travel but the fork dives on descents, even with low speed compression cranked up.

    Thanks, mine work well mid travel and now I have dropped the air to 60 they are great, and are getting over 100mm of the 120mm all the time. Haven’t bottomed them yet mind you.

    Did anyone else find the “stick” before traveling??

    This.

    I just ignored the pressure guide and set mine to 25% sag and 4- clicks from fast rebound. On “trail” setting 2 clicks down from firm.

    I’m 190lbs and struggled to get the pressure right to get max travel without being too harsh or too soft, until I fitted a MRP ramp control. This enabled me to drop the pressure, I currently run 70 psi, which gives a plush feel but I can tune the ramp control, variable token control, to prevent too much dive under pressure. Works for me. Slightly amazed that the ramp control functionality isn’t standard on all forks. I change the setting depending on what I am riding on.

    I have 34 performance elite on my trance 1, I have noticed I’m not quite bottoming out, I’m 11st wet so need to drop the pressure a little.

    Awesome fork , would go as far and say they are better than the pike rct3 I had on a trance 27.5 that I bough brand new and the pike solo air on my reign which was also new and I regularly bottomed them out when riding (with 2 tokens) big jumps and drops

    The fox 34 just seems a lot more subtle and plush in every situation and firm enough when needed!
