Chickadeehill AWK Air Spring - Review
@tremeer023: Glad to help! Yep for me that´s exactly what it sounds like. Tokens/ramp control affect the later portion of the travel, and with AWK you can tune the whole curve. I dont exactly know what the limits of the system are, if you pump of the secondary chamber extremely high in theory it should have a similar effect to a volume-reducer like tokens. Depending on the ratios of the pressure of both chambers you get a different looking curve. I wish the article had gone more in-depth on the physics behind this, maybe different graphs for different ratios, but oh well. I can guarantee that with this you can tinker a lot more than with the MRP though

Chickadeehill AWK Air Spring - Review
@uphill-blues: I´m glad to read your nose is okay after this mess. I set up my fork for the parts of a ride that interest me most, for me its the fast stuff. So relatively open LSC and more air pressure to counteract + 2 tokens for the bigger stuff. And yep on slower sections its not being used effectively, but I dont care if the fork doesn´t use 150mm of travel when going uphill, as it would probably slow me down while pedaling. In the end you have to find the compromise that works best for you and your trails. And I also heard that phrase not only from Gwin but also from a few other racers, but they´re riding on 10 levels above me so I take it with a grain of salt. If I were to put 150psi in my Pike I doubt that I´d be faster and more controlled, again I use what feels best for me (and sometimes I compare strava times, but as I´m progressing my skills I´m faster every time regardless of setup.. so objective testing is difficult). @acali: I only can write about theory or what other people wrote in the German forum where Chikadeehill is active, and your problem is exactly what the AWK is about. Low main pressure for good compliance and high second pressure against the mid-travel-diving and also a certain bottom out progression.

Chickadeehill AWK Air Spring - Review
@tremeer023: I´ll just copy my comment from below On the air spring curve you see in the beginning it is very steep, then flattens and then gets steeper again. This means: in the beginning you have a rather harsh feeling, meaning bad small bump compliance. This is why negative air springs are so popular, they "preload" the fork and thus help overcome this first bump. Bigger negative spring has a stronger effect, this is why Debonair, EVOL, Luftkappe and similar got popular (youtuber andrextr has a very good video on the effect of negative springs) When you put tokens in your fork (or the MRP ramp control, which is like a token that only gets activated if a certain movement speed in the fork is achieved), you just decrease the positive chambers volume. The last steep portion of the curve gets even steeper = more difficult to compress the later portion of the travel (end stroke progression). Also it starts to steepen a little earlier than without tokens, this is why many people (imho erroneously) say that "tokens increase mid stroke support". Since many people set the forks pressure so that they dont get hard bottom outs, when you put more tokens in you can get by using a lower pressure and thus have better small bump compliance. Increasing compression damping will result in a harsher ride. I personally would rather have more air pressure and less damping (My settings with a stock Pike RC are for my 90kg: 90psi, 2 tokens, about 1/3 clicks in). I´m also using the LSC to counteract the air spring, which is wrong in theory but works well enough. If the air spring was linear in the firstr 2/3 part of the stroke I could probably get by without compression daming, but hey the fork still feels very good and I´m no WC rider. Now the AWK has two positive air chambers, and depending on the pressures of each one its possible to tune both mid-stroke and also end stroke progression, which was kind of described too short in this article in my opinion. If you pump up the second chamber very high you also get the "token-effect" in the end (second chamber starts compressing when both chambers have an equal pressure), but it would start earlier in the stroke, depending on how many psi´s are in there. This makes it possible to set the main chamber with a relatively low pressure, having very good small bump compliance, without the diving caused by the flat mid part in the curve. And you get to keep the end progression for those bigger hits. Hope I helped and didnt make it worse :D

So yeah I´m seriously considering getting the AWK but the price and the reasoning in my head that the fork I´m using is still very good in a grand scheme of things put me off. Hope I helped and didnt make it worse :D

Chickadeehill AWK Air Spring - Review
I wouldnt say so, the charger is a good damper, and with this you get an amazing air spring. Compression damping should not be used to counteract a bad air spring, but on a solo-air you have to

@mollow: No, tokens only increase end-stroke ramp up (which if you add a lot of them will start affecting earlier parts of the travel) - but never fix the inherent mid-stroke wallow from any single air spring.

1 Question - What's Going on With 27.5+?
Really depends.. for me when theres lots of small bumps (roots or stones) and flat turns its amazing when dry, but in the wet or hardpacked berms its pretty shitty

What if You Could Design Your Dream Bike? - Pinkbike Poll
Longer = More stable at speed especially over bumps, adding to the overall wheelbase. Also like a longer reach it will diminish the effect of shifting your weight front to back, meaning if you stand on a slightly wrong weighted position over the pedals it wont matter as much. You will need more force to manual (I personally do notice 5mm difference), akin to using a longer stem. Shorter = the opposite, muh playfulness
