Clint.....thanks so much. I am 64, retired Navy....my wife “allowed me” something I had wanted for a long long time....a custom dedicated bikepacking rig.....to get me into backcountry fly fishing locations. So I built up a titanium Chumba Stella. All of my research didn’t prepare me for how the “technology” of bicycling has changed. And my Fox 32 fork is a perfect example....I picked it based on a short test drive on a friend’s mountain bike. Your videos on this fork are outstanding.....Bravo-Zulu on an educational and timely (for me!!) video!

It has taken me such a long time to get my head around this topic. I have the fox 36 and Float x2. Both have HSC and LSC and understanding how this works has been a bit of a mystery until this video. I may have misunderstood but I think I heard you say something to the effect of rebound being a bit of a "set and forget" scenario. That makes this a way easier process if I don't have to adjust rebound every time I adjust compression damping. You have helped me understand what LSC and HSC do and I have set my shocks and forks accordingly. Can't wait to feel it out on the trail. Thanks for a great video

For most people, rebound settings are indeed set for your weight and pressure and then forget it. However for people who do Enduro and downhill racing, they may speed up or slow down the rebound depending on the type of course. But for the every day rider after you get it set you’re pretty much done.

Hi Clint, have you ever found yourself adding some air pressure to the fork without any impact on its SAG? I'm testing a couple of NEW forks and dampers and it looks like the SAG doesn't always change so quickly with the air pressure increasing. I have the suspension fully opened. Would you say the models I have can just be sticky as new and never ridden?

+ShaiBike the fork seals on new bikes need to be broken in. That's why I recommend cycling the fork a few times before setting the O-ring to check your sag. That's probably what is happening. The fork seals are just sticky.

Clint, I just rebuilt my lowers on Fox 34 FIT4. I also have a newer Fox 34 Grip. The problem I’m having is getting the sag set up without using more then the recommended air per rider weight. Fox recommends only 120 psi max, I’m 180ish pounds and the amount of air I put in is 118 psi. The real issue is w/o riding and during my mounting the fork used 90% of the travel full open or mode way, can you explain, UGH!!

I wonder if those volume spacers fit the older Fox CTD forks? I have a 2014 32mm 120mm travel factory FIT CTD fork and actually added some float fluid into the air chamber to make it more progressive, those spacers seem like a smarter option but nowhere do I see them listed for my fork, do you know possibly offhand if there is a solution for the old Fox 32 mm stanchion forks? Also another thing to note for readers is at least on my fork the 2nd adjustment affects the middle position (trail) on the older forks and not the fully open setting. I checked out the trails too at Croom you reviewed awhile back, tons of fun, just wish the entire thing was like the challenging sections. Interesting theme they have going with liquor and underwear along the trails. I would avoid that though again after a rain, those mining pit sections were very very slick today.

Hey Clint, is achieving full travel the ultimate goal if one rides the same trails all of the time learning to and or first setting up the suspension? I have the same fork as in the video, what's a good reference point to start in when messing with the compression dial? Fully open, mid or firmest setting? As with rebound, Fox's recommended rebound setting is from fully closed contrary to your previous guide on how to set up the suspension (and i'd agree with you btw) so wondering what's worked best for you when dialing in the compression dial. Cheers on another great video!

@ClintGibbs
@ClintGibbs Жыл бұрын
Air pressure determines how much the suspension can move. The blue knob is a compression lever which determines the forces it takes to get the suspension to start moving. I know that may not sound super clear, but my recommendation is to get the SAG right and then fine-tune the feel with the blue knob. Proper sag also Helps with the negative travel. That is, helping the wheels stay connected to the ground, when there are divots or G-outs in the ground.

But bringing another dimension into this; if I adjust air pressure to get correct sag but I feel the suspension is too soft and bottoms our, should I then use the lever to make it more firm or add a volume spacer? My own guess would be if it is too soft but not bottom out = use lever. If too soft and bottom out = volume spacer and perhaps lever too if still too plush. 🤔

the fit4 in medium setting is actually the open setting in the 22 clicks. I usually ride the medium or the open setting in the 12 clicks. The fox 34 is not a DH fork, but i find it more good on the medium setting, so you don't bottom out the fork, even with the big volume spacer (i have the one from Push Industries, because my fork is a 34 from 2012 with the fit4 upgrade, and push industries volume spacers)

For XC type ridiing I leave my compression settings in the middle. Riding in the mountains I will leave it in the middle for climbing and then open them up for descending. It's really not a big deal to just reach down and flip the lever on your shock and then on your fork before you start your descent.

@Oh_Sully23
@Oh_Sully23 4 жыл бұрын
Lyrik Select + has low speed compression adjustment via the dial on the top of the right fork leg. If it's like the RC2 damper there will be 18 clicks. You can think of low speed compression damping being used to control the compression of the fork due to input from the rider, such as weight transfer when under brakes, or climbing a steep hill, even pushing into the bike in corners and pumping in flowy terrain. The more damping you add, the more force is needed to compress the fork. There is no bypass as such so the low speed compression will have some effect on high speed hits but it will be most noticeable on smaller bumps and slower shock speeds.
@yvonjasser
@yvonjasser 5 жыл бұрын
Low speed adjustment should be called initial adjustment . Every times a shock or fork go into high speed, it has to pass thru what they call the low speed. Furthermore the low speed adjustments do affect the high speed dampening quite a bit. Try it, crank the low speed compression to the max and you will see your forks will feel stiffer everywhere.
@piciu256
@piciu256 5 жыл бұрын
Actually it's the other way round, the low speed does offset damping a bit, but it's the high speed compression that limits its range, see the high speed as a valve that opens when enough force is applied and the low speed as a bypass around that valve, which varies in size.

WHAT??? You ADD compression for harder hits? I have found the exact opposite. Maybe if the fork psi is low, yes, you don't want to bottom out and so I guess you could add compression to avoid too much travel. The compression on my XC bike is extremely sensitive, and I often ride it completely locked out. I've even added 15 more psi for my weight to 65 total to lessen the travel so I can actually use the max compression setting before lockout. It's actually too squishy even for light trail riding, so I often keep it locked. I usually don't set the compression below max, or one click away from lockout. Only if the trail is steep and chunky do I lower the compression down, and it's rarely completely open. I guess it really is subjective. But it does for sure feel better more compressed and my downhill times are in general faster if it's more compressed. Downhill being a 'normal' trail or technical XC usually between a 3-8% decline, 9%+ would be more a more open setting. After using a Suntour fork (with no compression option) for a couple of years, I have found compression with my Manitou Machete and Mattoc to be by far the most useful variable on a hardtail besides tire choice, even if the compression is usually not 'varied' if you get my point.
