I finally had the opportunity to get a little saddle time on my 2011 fox 180mm float Rc2 and noticed I never get full travel. Today I decided to measure the length of my stanchions out of curiosity. To my surprise, my stanchions came out to a whopping 194mm's in length. I measured from the top of the dust seal to the end of the stanchion. Has anyone else had this issue? Any pertinent information would be greatly appreciated.

so you're gettting 3mm short of full travel? and you have 14mm of stanchion more than listed travel? what the problem is?

 

[Dwdrums00]

Jon, to be honest I haven't accurately measured the forks max travel. I just noticed the O-ring wasn't getting anywhere near the crowns so I started to play with HSC and air pressure.

UPDATE: I decided to air down the fork and bottom it out. The fork is getting 187mm of travel and has 7mm of stanchion left until the seals hit the crowns.

you don't want the o-ring to max out at the crowns. you always want some space between the crowns/arch when bottomed out.

I understand that. Especially since there is a bottom out bumper and you need tire/crown clearance. That still doesn't explain why I am getting 187mm travel and not even hitting the bottom bumper very hard.

i dont get it. are you trolling?

187mm form a 180mm marketed fork sounds good to me. i would have expected the marketing to over sell.

 

[frango]

What about axle-to-crown length? Is the fork higher, too?

 

[MmmBones]

If you had a shorter ruler you wouldn't have this problem.

Fox forks by design have few milimeters longer space between seals and crown. When you bottomed out hard, you just compressed bottom-out bumper which is there to save your fork from serious damage. It's OK to use 160mm of travel and have the last 20mm for some unexpected hit.

I have a 180mm fork with 194mm of stanchion showing. My axle to crown is approximately 578mm when it should be 565mm. Tell me, how is that trolling?

My axle to crown is approximately 578mm.

i understand your concern - i'd call fox and ask them about it.

The advertised numbers are rounded out to make it easy to remember/say/sell/whatever. I know that back in the day my Marz forks never had quite as much travel as advertised.

When? I bottom my 66 RC2x 2007 (180 mm) at 175 mm. And a 2007 Drop Off Triple at 165 (advertised 170).

The forks I am talking about were pre 2000 crazy huh? I'm just making the point that the measurements listed in the manufacturer specs are consistently wrong.

 

[kidwoo]

That's normal on all fox single crowns. Bottom out is not seal against crown.

True, but axle-crown is 13mm more than it should be. And that fork is long to begin with (@ 565mm).

Unless Fox's listed specs are all BS.

Fox air forks are a little frustrating in that there's a top out spring you need to be aware of that most certainly changes its resting point with air pressure. I've put 3 30mm travel reducers on a float once, cranked the air pressure to ungodly levels and ended up with a for that extends 110mm when it should have been 90.

How much pressure you running in that thing? You may have the top out spring maxed or close to it.

I just spent 2 minutes watching a dude in a canoe.
Damn you woo!

Only two minutes? You missed the best part!

 

[Dwdrums00]

I am running around 82psi in the 180mm travel setting.

 

[Jeremy R]

I just measured my 180mm Vanilla for you.
The stanchions measure 185.5 mm, and axle to crown is 565mm.
I have pushed the o-ring almost to very top on a couple of really hard hits, so it looks like I am getting full travel as well.

That was pretty impressive.

that's what keeping you from the podium in sport class?
