    Axle to Crown measurements on new 29er PIKEs ?

    Has anyone seen AC numbers for the new PIKEs?

    Am interested in the 150mm 29er versions. Would like to know if they are taller than the F34 29er OE 150mm forks.

    Thanks

    Thanks chpfly - are these measurements listed on the Rockshox pages anywhere?

    Interesting that the AC measurements are correspondingly lower than the F34 equivalents ( that I have anyway)

    My 2013 F34 CTD 150mm Floats OEs are approx 568mm
    My 2013 F34 CTD 140mm Floats are approx 561mm
    My 2012 F34 RLC 140mm Floats (ex TALAS) are approx 567mm

    I might be wrong, but I thought the Fox 34 140 was 552.8 mm?

    I will say that my 150mm Pike is shorter A-C than my 2013 Fox 34 140mm.

    So either Fox's or Rockshox's numbers are wrong.

    In reality the Pike is shorter.

    If I replace my Fox 140mm, should I get the 150mm Pike? Do you think the A to C distances would be comparable?

    I can tell you that my 150mm Pike is approximately 7mm shorter than my 2013 Fox 34 Float 140mm. So you can definitely up the travel with the Pike without raising the front end at all vs. using the Fox. The Pike is also about a 1/2 lb lighter.

    Pike 29er 120-150mm Dual Position has 565mm A-C in 150mm mode. Measured mine.

    If the like is 565 at 150 then it would be 555 at 140. How would this be lower than foxs 552.8 at 140? Even more drastic, how would 565 be lower than 552? Is fox really higher or is SRAM lower?

    Pic explains it all- Pike 150mm vs. Fox float 140 RLC (both 29 of course).

    Exactly, the Pike Solo 150mm is shorter A-C than then Fox 34 140mm. I can't speak of the dual air version 150/120mm.

    I wish we could get to the bottom of why the published numbers seem to be wrong.

    Got my Pike 150mm Solo Air last night. So impressed with the build quality of this fork. For people who may be put off by the price, I was surprised to see that it comes with a shock pump, a star nut, a full rebuild kit, and two of the tokens that let you tune the air spring volume. So far, a premium experience. Compressing it with my hands, it felt very smooth. It also looks burly and feels light. The install will happen Friday night.

    I believe the Fox forks have some dead space in the stanchions.

    Re: Axle to Crown measurements on new 29er PIKEs ?

    Measured a 2013 fox float 34 140 and a pike 140 51 last night. The pike was as advertised at ~551 and the float was ~7mm taller.
    Oh and there was a 12g difference between the two. Weighed without axles and crown races; starnut was installed in the fox, and both steer tubes were cut to ~7".

    Pike 150mm Solo Air 29. Measurement from top of crown prior to crown race installation, down a line parallel to the steerer tube: 560.5mm. I've had two beers.

    Edit: the same procedure on the Float 34 140mm gave a number of 551mm, which is pretty close to states as well. I have a picture that clearly shows the 150mm Pike has a larger A to C than the Float 140mm. Colin, are you sure your Float isn't 150mm. Another difference is the top out behavior of each fork. The Pike has an air negative spring and the Float has a coil negative spring. As a result, the unweighted equilibrium position of the Float can still be extended by pulling the crown and axle apart, even at 100 psi. The unweighted Pike is at full extension.

    Also, If you look at where the stanchions enter the lowers, the rockshox stanchions enter at a lower point than the fox... basically the lowers are a tiny bit shorter on the Pike, and the crown sits down a bit further onto the stanchions as well. And yes, from other threads the fox 34 is capable of being set at 150 (at least the 2013 was) without changing the stanchion length, so the Pike and fox look the same. My buddy has a fox 36 160mm and can never get the o-ring all the way to the top, even with no air in it, which makes us think the stanchions are the same as the 180mm fox 36.

    well 12 grams even with the starnut sure isn't the half of pound difference that there is on paper. c-wal - do you remember the weights? was fox less or pike more?

    My Fox has more exposed stanchion than the Pike 150mm. Who knows? It was supposed to be a 140mm. I never measured it or realized it was long until I got the bike. No wonder my Ripley handled odd with it...

    I do get that "top out clunk" when I pull up on the fork crown while holding the wheel down, a separation effect as you described.

    My Pike 150mm weighed approximately .4 lbs less than the Fox. That was with a full length steerer on the Pike and a trimmed one on the Fox. Axles and crown races on both.

    I think my Pike as 4.3 lbs straight out of the box if I remember correctly.

    Sounds right. Mine is right at 4.3 lbs out of the box. Weighed with uncut steerer and maxle, but no star nut.

    So let me sum it up for everybody since there is too many confusing data on this thread.

    140mm Pike is EXACTLY same height A/C as Fox 140mm. Right?

    Pike is not longer or shorter but is EXACTLY the same as Fox at 551mm? Correct?

    Because I need to know for sure before ordering Pike with 140 or 150 mm to replace my current 2013 crappy Talas.

    Please let me know if I got it right.

    But we are pretty sure your Fox 140 was not actually a Fox 140, right?

    Well. I am looking for advice. I have 140mm Talas 2013 that is trying to kill me. As long as I enjoy long steep climbs and Talas option I was recently climbing without dropping height just to see If I can make it without this function. Yes I can. I use Tals option sometimes and sometimes I forget even about it. So I guess dropping my fork height is not crucial but is nice.

    Now. I want to order either Pike solo 140mm or Pike 150mm Dual (to still have dropping option). At the begining of this post people said that 150mm Pike is same or even lower that 140mm Fox. Later you say they are the same. So I am just trying to get facts straight. However maybe you can recommend 150mm Pike instead of solo for some rason. I just don't want to screw up my bike's geometry (but extra 10mm could be nice).

    Any opinions?

    I would personally stay at 140mm. I went from 140 to 150 on my Tallboy LTc, and while it rides fine, I don't think I'm benefitting from the extra 10mm of travel, and it does very slightly hurt the climbing performance on really steep, technical pitches.

    So why not lovering it down to 120mm on climbs. That's the point of Dual.

    Because the stuff I'm talking about doesn't necessarily come in the midst of a sustained climb, but in the flow of riding. I'm just not a fan of travel adjust forks.

    Well that might be right. Sometimes I forget to switch back my Talas to full. Sometimes I forget to lower it. That is why I am leaning towards simplicity of 140mm version.

    I don't think you'll regret it. The Pike is a great fork. I leave mine open 100% of the time and just ride.

    Still Talas helps on steep technical climbs. But, oh well... I think I keep it simple.

    Thanks for advice.

    So how do you compensate for sag when comparing the two forks? Presumably sag amounts could differ for the two different forks which would change your effective ATC measurement.

    You don't... you measure the A-to-C unsagged, since it is the only meaningful comparison. You might find the Pike works best at 30% while the Fox requires 22% to work... there's no way to actually e-bike about the resulting effects in the way the bike rides without just trying both yourself.

    Exactly my point. So all this hand wringing over the ATC on these two forks is pointless given the effective ATC (including sag) is the only meaningful measurement and the ideal amount of sag for each fork is an unknown variable. The only way to make a real comparison is to ride both forks and see which you prefer. Just my 2 cents.

    What you are describing is fairy dust and magic. There are so many variables that I won't even finish this comment...

    Simply saying... this is over the top. We use maths form real numbers. There must be a border of sanity somewhere. With your point of view there is no no way to measure anything. What if winds blow while you're biking will sag change? Of course.

    I hope you see my point...

    Unfortunately your point is incorrect. There is a way to get a much more realistic comparison which involves using effective ATC including sag (no fairy dust or magic needed). I have done several conversions of front suspension forks to rigid forks and to determine the correct ATC for the rigid fork the key is to measure the effective ATC you are running on your current suspension fork. This is a simple and straightforward process with the sag measurement process outlined in either your Fox or Rock Shox owners manual. Assuming you are have the sag properly set on your suspension fork simply go through the sag setting procedure (e.g. gently mount your bike with your kit on and hydration pack if you wear one and then gently dismount) and then measure the distance from the O ring to the top of the stanchion. Then look up the listed ATC for your fork from Fox or Rock Shox and subtract the sag measurement you just calculated and bingo you have your effective ATC. That is "math (no s) with real numbers". Cheers

    I am putting together an LTc and wanted to run the 150 Pike. Should I run a headset with an internal lower race to drop the front down? Do you think the crown will hit the down tube with this set up?
