PoiZoNouZ Posted April 17, 2014 Share I have a mate that just got a 2008 Gary Fisher HIFI Pro 26". It has Fox front and rear suspension, what air pressure should I use in the fork and the shock? The Trek website does not go back that far with the suspension calculator. He weighs around 70kg with all the kit. Link to comment Share on other sites More sharing options...
Mojoman Posted April 17, 2014 Share I set mine up according to sag and the way I ride and where I ride.I am 90-94kg with a backpack and have about 70-80 psi in the front and about 250psi on the rear. Best bet is to take a shock pump and go for a ride and play about. Be careful of not enough pressure in the front as the fork tends to dive when you brake hard. After a few rides you will see where the o ring (or if it hasnt got one where the dust settles on the stanchions) generally is and adjust it from there.

BigToe Posted April 17, 2014 Share I had a 2009 HiPro carbon and you can run 170Psi on the shock and 80Psi on the fork at his weight. Link to comment Share on other sites More sharing options...

Run mine at 160 psi and 93kg with kit. Link to comment Share on other sites More sharing options...
BigToe Posted April 17, 2014 Share Yes 250psi is hectic. I'm 95kg and run my Spark at 180Psi Link to comment Share on other sites More sharing options...
Captain Fastbastard Mayhem Posted April 17, 2014 Share Are you sure about the 250psi on the rear? Run mine at 160 psi and 93kg with kit. Lol. I run my dhx at 300. Max. And I still bottom out with 200 psi in the piggyback! Link to comment Share on other sites More sharing options...

PoiZoNouZ Posted April 17, 2014 Share The app only does 2013 and up Fox. Got it dialed 75 front 160 rear lets try. Link to comment Share on other sites More sharing options...
Mojoman Posted April 18, 2014 Share Are you sure about the 250psi on the rear? Run mine at 160 psi and 93kg with kit.I prefer it stiffer as i still ride around a fair bit on dirt roads. on the rough stuff it still uses most of its travel though.

MarcL Posted October 16, 2015 Share Good starting point for meYour weight in kg is your pressure in psi for fork and 2x for shock. Eg - 80kg = 80psi for fork and 160psi for shock. Then add or subtract at 5 psi increments to achieve desired sag Hope at helps Link to comment Share on other sites More sharing options...
Eddy Gordo Posted October 16, 2015 Share I had the same issue. I opted for a volume space. Seems to be working so far Link to comment Share on other sites More sharing options...
JXV Posted October 17, 2015 Share Make sure any lockout/damping adjustment is full open. Then set pressures to get about 20% to 25% sag front and rear when just sitting normally in riding position. Then fine tune to personal preferences from there. Link to comment Share on other sites More sharing options...
