Specifically an 04-05 model
What axle to crown is the Moment geometry based on?

From the web site: Moment--------------5" to 6" (125-150mm)*--<600mm (less than 23.6")
I guess your answer would be "less than 600mm", but that's not too precise. I think Ellsworth works with Fox a lot, so my guess is that they based many designs on Fox products. But there was no 150mm Fox fork when the Moment was designed. Three years ago, the only 6" forks were either dual crown, like a Boxxer or some form of Marzocchi or Manitou.
What fork are you thinking about?

Same question I asked Ellsworth.
Asked that same question - Am looking at buying a Moment frame and was wondering what Axle to Crown measurement gives the bike a 69 degree head angle.
The answer was "The measurement was taken with a Fox Talas 130. I do not have their tech bulletin handy. Does that help?"
I think the A to C on a 130 Fox is 500.9 (from Fox website).
Hope this helps.

Currently have a Firefly +. Pro's - it doesn't dive, works great when your haulin' oats & its easy to work on. Con's - not so good on the little stuff & not very adjustable.
I want to replace my Firefly + with a coil fork that is about the same height, weights about the same, more supple on small hits, low & high speed dampening, very adjustable & easy to work on. I think my only two choices are the Pike 426 or maybe the 36 Vanilla. Wishing the pike had another 10mm of travel and was a smidge taller and I'm afraid the Vanilla might be to tall making for a tuff climber in addition to the deep cup headset issue re. warranty.
Anyone go from a taller fork to a Pike?
I'm assuming a Pike with a shorter a/c will climb better but what's it gonna be like at speed through steep, gnarly, rocky terrain? Will I miss my Firefly +?

Z1 Fr 1 (2005)
Am running a Z1 FR1 (2005) on my Moment, it's OK on the climbs when in full travel (A2C is 538 I think), but with ETA it's great, much less front wheel wandering.
I couldn't be happier with the Z1 other than perhaps the Z1 Light (2006). I am led to believe that the head angle of the Moment is low 68s with the Z1.
Have ridden a Pike on other bikes but not the Moment, given that a few of the more respected Turner Homers ride the 6 Pack with a Pike, I am sure it would be fine for your application.

What about Marzocchi Z series forks?
I know of one guy who went from a 36 to a Pike on his 6 Pack. He loves the Pike as it is, but after 6 months or so, he's looking for something taller. Not making it a full 150mm fork I think was a mistake in the long run. As it is, Rock Shox has some weird ranges in their products, but with the elimination of the 115mm Reba, they're getting straight.
I'm not sure of the A to C on the 36 Van, but 160mm may be too tall. Plus, you have the headset issues, though you can probably get a cheaper HS than the King.
Marzocchi forks are famous for their taller A to C lengths. You might look at some version of the Z1 that has Travel Adjust in order to tailor the height to your needs. ETA gives you good options on climbing, too.

Response from Ellsworth...
....69 ° with a Fox Talas 130...next year,
it's 69° with the fox 36.....
Just heard back from Ellsworth. Got the answer to my original question.
I am going to wake up in the morning and pull the trigger on a Pike!
Thanks everyone for your input!

Sorry for the confusion. I dont know who you spoke with but the information you posted is wrong.
The Moment 04-05 & 06, as well, has a 69deg HT angle with a 5"(495mm a2c) Talas fork. A Fox 36 (520mm a2c) fork slackens the HT angle to 68deg.
There is no geometry change for 06
Hope that clears it up

I posted this a long time ago but here it is again for reference.
Measurements taken from my 2004 Moment (unsagged) w/ 2.35 Nevegal tires on XM321 rims, Fox Vanilla RLC 125 fork & 7.875x2.25 DHX shock.
BB height Ground to middle of BB = 14"
HA = 68.5 degrees
SA = 72 degrees
Effective TT = 22.25"
Standover = 31.25" at pedal spindle with horizontal crank
Weight - small Frame, seat collar, DHX w/ 600lb spring = 7.95lbs

I emailed ellsworth a few weeks ago asking them about the printed head angle they had in their 06 catalog. I also asked them what the head angle would be with a 19 inch frame and 06 z1 150mm fork. They responded that with a 125mm fork the head angle is 69 degrees and with a 150mm fork it would be 67.8 degrees (Z1 specifically).
