Fox fork set up advice?

boz64

Hello all

I've had a look on the tech FAQ etc and searched the forums but could really come up with the advice/answers I needed. I'm sure this question may have already been asked before so please bear with me.

I'm something of a newcomer to air-sprung forks, having fairly recently bought a Trek EX8 (09 model) fitted with a set of Fox Float 32RL 130mm travel forks. Through a combination of laziness and certain amount of naivety, I simply assumed that fork would be set up in such a manner that it might suit a cross-section of riders. Daft I know! I have just discovered that the forks were pumped up to around 150psi... I think I may need half this!

Anyway, my question is this... can anyone give me some air pressure and rebound figures as a starting point to setting up my forks correctly. I seem to get different answers to this question depending where I look on the internet. The Fox manual I got with the bike even appears to contradict the Trek advice.

I understand that suspension set up is ultimately a highly personal thing depending on rider characteristics, type of riding, terrain and just plain old like and dislike. But as I say I'm just after a starting point.

I ride, currently, mainly at trail centres, and I weigh around 10 stone. I would describe myself as an intermediate rider in terms of skill/experience.

Many thanks.

just set your sag to 20-25% of the travel while in the attack position.

the pressure needed is what every you need. and then tweek on the trails from there.

Hi

Thanks for the quick reply!

So for my 130mm forks that would be around 30mm. I'll give it a try as a starting point. By the attack postion I assume you mean weight slightly forward, arms bent, back flat-ish? Any tips on a starting point for rebound adjustment?

Just as a matter of interest, would i be right in thinking travel is measured from the top of the dust seals to the point where the fork leg meets the crown? :?

Cheers!

Put a zip tie around the stanchion. Push it right down, then get on the bike in the 'attack' position, standing up, with a fair bit of weight on the bars. Then get off and measure how much the ziptie was pushed up, that's the sag.

Step 1 select your fork from the list.

Step 2 watch relevant video/videos

just had a quick scan through and it is easy to get and shown well.

and now easy to find.

I especially like the bit where they show the different riding styles and how it effects things. (sag)

+1 Nick very clear and easy to understand. The bit about bracketing is good I'm just not to sure why Fox have chose to hide it away in the bottom right hand corner of their site. Even though I knew it was on there, it still took me a good 20 mins to find it again. Bloody Wood for Trees etc. :roll:

just watched that.

mmm very hard to get the answer.

but just like we do with the race cars but we have an additional input the log files from the telemetry recorders. Was fun working out what the driver really meant.
