Also, the rear axle is effectively a suspension pivot that the wheel rotates ever so slightly around as the swingarm moves up and down and the wheelbase changes (bounce up and down with one or both brakes locked and you'll feel it). Depending on the design, the use of the rear brake restricts the free motion of this pivot to a greater or lesser degree which can account for that slightly harsher feeling even when the suspension is sitting high in the softest part of its travel. I personally always liked the feeling this sort of feedback provided, and back in the day had an Orange with and without a floating brake. Stability felt pretty much the same on both but it was the lack of braking feedback with the floater that eventually made me go back to the standard setup.

I think there's a place for timing, particularly for DH racers, but I'd also hesitate to put too much stock in that alone, or really at all on a trail/enduro bike. For non-racers time might not be a factor at all if the goal is a more comfortable, controlled, balanced feeling setup. And for enduro racers I can speak from my own experience last year using a DAQ system to optimize the setup on my 2 minutes bike park tracks. Sure, I shaved a bunch of time and the bike felt great on a hot lap but the challenge comes in trying to ride that same setup on a 6-12 minute enduro stage, semi-blind, at the end of a 5 hour day. Even the settings published in this article are more firm than what I raced on a few weeks later which is why I specifically used the MIQ system to find a softer setup for racing. On the clock going full gas at the bike park it might have been a bit slower, but no doubt over the course of several long stages of racing it would be faster and far less fatiguing.

If anyone's curious how that differs from the slightly firmer setup:
Fork 80psi, 1.5 spacers, 11 LSC, 7 HSC, 9 LSR, 8 HSR
Shock 162 psi, 2 spacer, 16 LSC, 8 HSC, 16 LSR, 8 HSR

It might not have been clear from the video, but this was never intended to be a play-by-play account of the first 4 weeks testing with Motion IQ and the various changes we ran through. I'm sure there is an audience for that out there somewhere, but it's likely to be quite small. With the volume of data this system produces we decided it best to focus on a few of the key features of the system, how to read the respective data, and how we translated this into adjustments on the bike. Because this is a product review first and foremost, we tried to present it as such which comes at the expense of condensing the other half of the story.

'Just to make sure I have this right, it showed you to open up the chamber of your fork and speed your rebound out back, right?'

No, not at all. That's one particular data point from one or two runs at a bike park after a few weeks getting a base setting on my home trails. Much the same as you would do when using any DAQ for racing to fine tune settings from one venue to the next. I'm sure you've watched some of the 'Dialed' series and this is what most of the head scratching is about; small adjustments to address specific handling characteristics due to changes in terrain, speed, temperature, weather, confidence, etc.

'Hell, I could attach a gopro and watch my suspension and learn many of the same things you learned here...'

Having done just that for quite a few years, yes it's helpful if things are way out of wack enough to see them visually, but if I showed you the GoPro clips from these sessions and told you to line each up with it's respective data set you wouldn't be able to discern any visual difference. In part, that's because there's a point where we may just be splitting hairs but I'd argue that's exactly for what (and for whom) this sort of technology is intended.

If you're more interested in the depth and breadth of Motion IQ beyond what we go into here, I'd highly recommend the 40 minute 'deep dive' video from MI that's linked in the article. https://www.youtube.com/watch?v=KUrhA3kS3eU

If I had to guess, I'd say he's reinstalling the damper cartridge and filling the leg oil from the top rather than the bottoms so he doesn't have to take the bike out of the stand and flip it over.

Soon enough. Thats actually what we were filming for but ended up with enough riding footage to slap together a quick edit.

Sound like the new X2 has a tighter range of adjustment or slightly bigger steps between them. 8H/16L on rebound and 10H/18L compression give or take a click or two. The current X2 is 23 or 24 for everything. Neat.

Some paint stripper gel from the hardware store and some scraping to get most of the original finish off, a rotary sander to remove the rest and give it a bit of a rough shine, but not so far as to polish it. The back side of the arch is actually painted silver to match rather than trying to get all the red paint out of the honeycomb sections. Finished off with a few layers of urethane clear coat.

Bingo. Turning a bike upside down is good idea too, but can take a while or not really flow too well past the bushings especially if its cold. Notice in the video no oil comes out when I purposely lifted the seal past the stanchion? That's not because there isn't any in there, this fork is maybe 5 rides in to a rebuild, it just hasn't made in that far even after being upside down for about 10 minutes while shooting.

Don't care for it, have your own routine, prefer to leave service to your shop, don't regularly clean/lube the lowers already, then feel free to disregard this. But, I should add I learned it from a suspension tech who will remain nameless back in the early years of the EWS when sites were remote and race support, service, and supplies were far more limited than they are now. When you have to work several weeks out of a suitcase in tiny european hotel rooms or the back of a rental car in field somewhere, you have to get creative sometimes.

And then for an encore I touched the brake rotor with my bare hand and laid the bike down on the drive side. The horror!

Same, but I don't usually travel with fork oil and some people still find that part daunting, messy, and/or time consuming. Also, that might not qualify as being lazy enough. The point is not to replace or avoid service, but to keeping them feeling as fresh as possible in between. I've found it works a bit better and lasts a bit longer than simply holding the bike upside down for 30 seconds.

You don't need to if you are just removing the lower legs. But you would definitely need to release the air if you were going to unthread the top of the airspring.

Imagine your own fork, then drop 6-10 psi. It's not just corner and brake dive that suffers but also chassis stability (particularly at the handlebars) and an imbalance with the rear shock. I was able to tune out the dive, increase the dynamic ride height, and bring back a degree of stability with a combination of preload and compression damping but it was to a point where the fork lost its sensitivity and was overy harsh (approximately 8 clicks/halfway on the preload dial and well past halfway on compression with the lever at about the 4-5 o'clock position for lack of a better reference point).

Of course how much dive you feel would depend on how much you are willing to tolerate in the first place and your particular pace and riding style. I ride with a number of people who at the same weight would have had no issues with the medium spring. For reference I weigh between 155-160 pounds in riding gear and usually run a 170mm Lyrik with a single token up to 80 psi and two tokens as low as 75 psi. The medium spring on the Z1 felt similar to dropping the pressure about 8-10psi.

A challenge with reviewing suspension, and coil suspension in particular, is that it relies so much on the individual testers preferences. I rode the fork as if I was planning to race an EWS with it (albeit in Masters, but still at a fairly competitive pace) and used that as my benchmark. Could I feel comfortable riding it at that pace? No, but that very likely makes me an outlier as far as setup goes.

It’s not sealed on the damper side, unlike a Yari which is.

Spring rate is spring rate regardless of what else you do. I remember using this same trick on older DH air forks, where we'd compress them an inch or so with the foot bolt loose and get a slight vacuum effect and a bit more sensitivity. Doing that in this case 1) might also introduce preload and 2) not change the spring rate which was overall too stiff. To tune just the bottom out feel you could +/- a few cc of oil to alter the volume. Marzocchi says not to, most likely because the the window is a couple cc's either way without putting too much pressure on the seals and ending up with a customer service issue they'd rightfully prefer to avoid. My issue was the overall rate, not just the resistance at the end of the stroke.

The best fix would be a better selection of spring rates.

It's a one-off custom color, a tip of the hat to the original Team Yeti ARC frames I drooled over as a kid.
