sorry to bump an older-ish thread , but im realy chasing a bit of help regarding my pikes , they are Pike 454 U-turn Air.
what is the maximum pressure i can run in them safely?
do i have to run air in the negative spring chamber ? ( i found that when i put in 170psi + chamber , they are solid as , but when i add the equal psi in the negative chamber they become very plush , what does the negative chamber actually do?)
will riding park/dirt with the compression on full lock damage the fork? same goes for floodgate?
Fork is lowered (75mm-110mm) , will be used for dirt/park/street style riding etc.
It basically causes an opposing force to the positive chamber. I used to know about what you could run in it ect but don't any more. You can run full lock with a high set floodgate as ultimately it has a blowout. But if you run a rock front end just to rigid, and if you go rigid get a bmx. Run them firm and learn to use the sus

cheers!
The air chambers are designed to both be used together, I ran mine with positive chamber slightly higher than the negative chamber. A larger difference between the chambers (positive higher) sets the fork up firmer, smaller difference makes the fork better for small bumps (as it seems you've found out). As for the lockout, I ran mine locked out by accident for the 1st section of the Fort William WC cup track. No damage, except my wrists.
cheers guys , much appreciated! I'm Running 170psi + / 50psi- rode it today on about 3/4 compression with floodgate about half on... was probably the best combination I found i ran
what i found was it wasnt too active in the initial travel ( e.g when you're pedalling hard or small bumps in the bowl or run up to trails)but still absorbed sharp small hits, but i still got about 60-70% travel when compressing hard (going up a quarter pipe/hitting an upramp etc)... dont think I bottomed out at all today , but from what I felt it would reach full travel if i needed it.
seemed to be pretty awesome , not too active initial travel , but still active when needed.
running it with no compression and no floodgate was also quite fine , but i prefer the feel of the compression on as it kind of has a initial step then a big hit step
just my
edit : this was at 100mm of travel , not that that makes a difference haha
Its kinda interesting, are you suggesting that negative chamber should be equal or a little bit lower than positive chamber. Mine is 454 DA 140mm I am currently use 100+ / 80- I am mostly use for xc/am.
I put compression in lowest and flood gate kinda middle.
I like this set up, but after read above explanation, will it better to put equal pressure in both negative and positive then crank the compression a little bit??
Got a question that isn't really worth opening a new thread for, so I figured I'd just post it here I'm in the market for a new fork to replace the Manitou Tower Pro 120mm currently in my 2Souls Quarterhorse. I want a fork that is sturdier and has more travel so it matches my riding style a bit better. I've decided I want a Pike, but I now see that the 2016 are already available...
What is the difference between the 2015 and the 2016 Pike (other than the decals)? Is it worth spending an extra 170 euro's to get the 2016 version? I already find 679 euro's a crazy amount of money, let alone 849 euro's, but if the the new one is that much better than the 'old' one..... well, then I might think about it. What are the chances of the price (2015 version) dropping when the 2016 comes out?
OK, so a little bit of afternoon research today - has anyone retuned the high speed (HS) shim stack in the Charger damper on their Pike?
I notice the latest release of the Pike service manual (revision D on 2015) shows how to retune the HS rebound.
However the Pike service manual doesn't have anything about reshimming the HS compression (only HS rebound).
I looked at the Boxxer service manual (Charger Damper) also and surprise they show how to do both the HS rebound and HS compression.
A comparison of the HS rebound shim stack on both Charger dampers on the Pike and Boxxer show them to be identical.
Now the point here,
1. Has any one seen this before? 2. Is the HS compression stack on the Pike the same as that on the Boxxer, and 2, Has any one played with the HS compression stack on their Pike?
I ask as my Pike feels really wooden on fast chundery runs and my LS compression dial is all the way off (all the way counter clockwise), thus I am thinking I may go to a lower (ie softer) HS shim stack for compression.
The service manual recommends if you are within 2 clicks full open or 2 clicks full closed on either the low speed compression or low speed rebound (on either fork), then to move down (if within 2 clicks from full open) or up (if within 2 clicks full closed) on the tune on the respective HS circuit.
The only difference it seems to move to the soft HS compression tune (from the stock medium) is to move one shim up the order to reduce its effect, thus making the stack softer.
