Nice, balanced review, JKW. Interesting how, over the same terrain, *riding style* can affect what you get out of CushCore. Never thought of that. Good point.

[@bowsineath1856]

I was drawn to CushCore to help relieve pain in my hands that is a result of some nerve damage in my left hand. I read a few comments online that indicated other riders, with similar issues, felt some relief on sharp impacts after installing CC. What I ended up doing was only installing it in the front, which is very contrary to what most other riders I've met have done, where most of them just installed it in the back. I found it provided some relief to my hand pain, but much more significantly, I found the bike cornered a lot better. I was on the Light/High Grip Vigilante, running about 22psi as a 215lb rider (mostly riding Pisgah in WNC), but I found dropping 2 psi and installing CC provided a lot more support to the tire in corners and made the tire feel stiffer. I think I had been pushing the tire to fold a bit more than I had realized, the CC provided more support and the bike felt much better leaned over hard. I didn't feel much of an increase in rolling weight or resistance with it just in the front. In fact, I was on a pretty steep climb following some XC guys on much faster rolling, lighter setups, and I was able to push it to keep up and ended up PRing my climb by over 10% after adding 250gr of rotational weight. A few weeks ago, I installed it in the rear, as well, and the increase in drag/weight was pretty considerable, but I also didn't notice as much of an improvement in the bike's performance. Granted, I was running slower/heavier tires for a few park days, but I felt the benefit of running it in the rear was fairly small, whereas having it in the front, I felt I had the benefits of having it installed, without many downsides. I ended up removing it in the back and have left it in the front. There is one downside that I haven't really heard discussed. It seems like CushCore prevents sealant from distributing around the inside of the rim, so if there are any imperfections in your rim tape or valve seal, then it seems to make your tire more likely to leak air and not seal itself. It's somewhat compounded by the fact that installing and removing tires with CushCore seems prone to damaging the tape.

[@JeffKendallWeed]

Interesting feedback Bow! I was reading your comment thinking front only has gotta be a riding style related thing, but you bring up some fair points. Now I'm curious about a regular CC in front and an XC version in the rear!

[@bowsineath1856]

@@JeffKendallWeed That could definitely be the case, I am heavier and tend to ride fairly centered (or even slightly forward, more than I probably should), so there is probably a good amount more pressure on the front than with some other riders, which would compound the difference I felt in the front and minimize it in the rear. What installing it made me realize is that at my weight, the tire was folding or flexing more than I knew, likely due to a combination of my weigh and body position. The CushCore added that factor for me to consider for me when evaluating tire feel, but also helped me realize that the added support really helps control the bike. I didn't get that same effect with the CushCore installed in the rear, though. The change was more subtle. It's possible I'm not pushing into corners hard enough or am not in tune with the tire flex/fold in the rear as much as the front. It's not also completely an apples to apples comparison, since I had it on a DHR 2.4WT EXO/3C and my normal trail tire is a Trail Boss 2.4, so it could have also been an effect of the different tire. I ran it for a few weeks, though, and the difference wasn't significant enough for me to justify keeping it in the back. I'd have left it in if the difference was significant enough to provide improvement and the tradeoff was worth it. The CushCore XC in the rear seems like an interesting idea, though, I haven't considered that before. It seems like it'd work well since most rears I'm running are 2.4 and the weight decrease is ~100gr claimed. I might give that a shot and see how it works out.

[@hardtailparty]

I really dig cushcore, especially when charging on my hardtail. I look at it as a suspension product. I don't feel like it adds the feel of more travel, rather I feel like it makes my bike's suspension work less hard. The tire ends up eating that first 12% of the suspension, so I can tune my suspension for everything the tires don't.

[@JeffKendallWeed]

How much lower do you go on pressure when running it vs without?

[@hardtailparty]

@@JeffKendallWeed depends on the trail and depends on which bike I'm on. Cushcore makes it feel a lot more damped to me, with way less tire rebound. I'll go 3-7 psi lower if there aren't any big g-out turns. I've gone as low as 11 on my plus bike on 2.8s dhr2s (stiff sturdy sidewalls) on 40mm wide rims. Usually in around 14-18 in the rear with cushcore. If I can hear the cushcore squeaking on bumps then I know I've gone too low. Trails like hiline, slim shady, ahab, whole enchilada, dr park, etc really benefit from the extra damping in the tires. Trails like Galbraith or demo forest or oakridge or bike parks like duthie dont benefit much from cushcore in my experience. I'm experimenting with front and rear vs just rear. I feel like in Arizona, southern utah, and Colorado it makes a ton of sense to run it rront and rear.

[@WasabiWei]

@@hardtailparty Thanks for explaining the damping effect. New info to me.

[@-Ola-.]

Late add-in `funfact` to this topic, but anyway; i dialed my fox faxtory 36 and float x2, with shockwiz before installing Cushcore, and retested it afterward for comparison.. No changes detected on the shockwiz.. (2-3psi less tire pressure on CC) I feel the bike calmed down alittlebit though, but no suggested setting changes on Shockwiz. Not saying this proves or throws down anything, just mentioning an experience/observation :) Love the cushcore.

[@TheyForcedMyHandLE]

112% of zero is still zero :D

[@trailjunkie7302]

Broke 2 rims in 2 weeks. Put a beefier rim on with Cush core front and rear. I am running even lower pressures and smashing my rim into rocks and roots on downhill runs and have had no issues at all. I’m running this on a Rocky Mountain altitude and LOVE it. Would not run it on an xc setup but for enduro it rocks. I’m 150# so not a big rider. I love being able to descend fast technical trail and then clear sketchy techy climbs with low pressure in the same ride.

[@PedalingDave]

Really good review. I'll be all in if I start flatting a lot. As of now I rarely flat, despite riding some pretty rough trails here and there. I particularly like that you are transparent and don't push every little thing as the "biggest improvement ever"! A much better, honest/realistic approach, and for that I say Thank you sir!

[@JeffKendallWeed]

Thanks Dave! While I'm not going to run it in my Ripley all the time, if I need to make that bike more burly, I'll throw some CC in there!

[@rpiian]

I love cushcore, front and rear. I live for the downs, and since I’ve run them I haven’t had any issues with flats or rim dings. I also love the support they provide in fast berms and g-outs, it’s super confidence inspiring. At the Sugarbush ESC Enduro (which is endless gnarly rock gardens) I ran pressures below 20psi for excellent grip. This was in combo with Maxxis EXO DHF 27.5x2.5 & 2.35 on WTBi29 F&R (respectively). They might not be for everyone, but it allowed me to rage with confidence on my Process 134!

[@Illsamustache]

I'm just your average 50+ trail rider. But I can tell you that CushCore Pro in both tires on my hardtail is awesome. I have Maxxis Assguy 2.5 front @16psi, and Minion DHR 2.4 rear at 18psi. They're like glue to the trail in turns, and are super cushy over rocks, roots and landings.

[@daveesau8557]

Thanks for a well-done review. I am a heavy rider (over 240lbs with riding gear) and CushCore allows me to run lower pressure on our PNW trails for grip on roots and rocks with no tire squirm. I did not put it on my wife's bike because she would not get the benefit but would notice the weight when climbing up to Evolution. I have a YT Jeffsy 27 and I did notice that it feels like it has more suspension when going hard which was a nice gift. I agree that it is a great product for certain riders but not all. nice to see you healed and are rippin' hard again.

[@lukeburgess98]

I love my cushcore insert. I blew threw 3 spank rims last season and after putting in cushcore I have had zero issues

[@shannonwade9933]

Word from Michigan. I’m running cores (bought from Jenson) on my rigid stache. The 3” is a sizable weight penalty but the performance to the traction and the protection for the carbon rims make it great product for the rigid bike trail rider. Thanks JKW, keep up the great work!

[@JeffKendallWeed]

Right on man!!!

[@chumpmtb2554]

I wanted to soften my Bronson up a bit for bike park trips, but didn't want to add all of that weight for local rides. I compromised and ran the lighter CushCore XC front and rear. They don't recommend for tires larger than 2.4, but I'm running 2.4/2.5 and haven't had any issues. I love super low tire pressures, so these have been awesome! The bike is now has a plush "magic carpet ride" feel, without having to drop too much pressure from the suspension, maintaining that supportive feel in the fork and shock. I'm digging it :)

[@JeffKendallWeed]

Right on Bryan! It'd be cool to get some of those lighter, smaller CC and compare them to the full on version.

Hey Jeff, I’m 6’3” 205lbs, I ride a Norco Range and really haven’t had any issues with my tires. This year I started getting into racing and have had to replace my tire and rim now. I decided to try cushcore on my new asymmetrical rim build after your review and WOW I can actually ride and fell stuck to the ground now. Got to say installing the cushcore wasn’t as hard as everyone made it seem.

[@JeffKendallWeed]

Right on man, thats great to hear! I think install depends a lot on which rim you are using. Glad they are working so well for ya!

[@Lucabran9093]

the point about making shorter travel bikes feel burlier could not be more true. I installed cushcore on my evil following with 130 travel up front and 120 in the rear. Before the cushcore, I was kinda regretting not going with an offering so i could have a little more meat on the bones. Not saying it wasn't riding great, but i definitely felt i was pushing the travel range. With the cushcore my prayers have been answered and my following could literally not feel any better. The idea that i have 12 percent more travel could not be more true. It definitely feels like more of a 140/130 travel bike with the inserts and its crazy how much of a difference that is. suuuuuuper happy customer here, if you're happy with your bike but hoping to stack a solid travel upgrade, definitely check out cushcore.

[@roryveronda9933]

[@jonasbanta7017]

I’m 190 lbs and love cushcore on my yeti 5.5, haven’t flatted since I installed them. I think that the install is a bit easier than it gets credit for (can imagine how asym would make it harder) but the only real trouble is tire removal. I have a tough casing trailboss on the rear, and have decided to leave it on until it’s worn enough to justify cutting off because it has become virtually inseparable from my carbon rim

[@rossgooding7423]

[@chasefrillman4114]

Cush Core with the ibis rims where pretty difficult to install! It seem to help to put the tire bead that sit on the wider side on first, then force the other bead on to the rim. Pretty hard to put on but hopefully its worth it. Very excited to see how they work on these new wheels! Thanks Jeff

[@FWCaptain-kv6sm]

[@FlowmentumMTB]

Great review as always Jeff, Like yourself I had not bothered with Cushcore and honestly myself I have never liked the feel of tubeless as you lose a lot of sidewall support and I am a 240pound rider so my weight, my style and Tubeless clashed somewhat.. App 4 weeks ago I purchased a product called Tannus Armour, this is designed to be run with tubes and goes between the tyre and the tube and wraps 270degrees around, you have less chance of a flat than you would with Cushcore, I am running 13/14psi front and 17/18psi rear and I am loving it, no tyre roll or squirm and soo much suppleness on the top surface I swear the first 1” of travel on my bike is no longer being used. I HAVE DEFINITELY discovered the fastest, smoothest and most supported trail system ever...

[@JeffKendallWeed]

Thanks for the note man! I have only heard one ride report of the Tannus system and it was not positive at all. But if it's working for you, then rock on!

[@SimonLehnhoff]

[@yipyipyip]

Thanks for the vid, I would think you would want a lighter tire with cushcore. I ride an insert (Tyre Invader) and use a Maxxis Forkaster 2.4 with EXO casing. The tire is light and the insert helps when smeeshing rocks.

[@SaleenS351R]

Glad you’re liking the Cush! Learning from @philkmetz, it was easier to install(get over the rim) pushing the bead into the middle. You have brought a rim design I wasn’t even thinking about, to light. I hope I don’t run into those when installing a CushCore. Haha. For me, I think they will be on all my trail bikes, long or short. Rim protection being another benefit from them, has me sold. Recently saved my rear wheel from getting banged up good, after riding about a mile of local trail before noticing a sidewall puncture near the bead, got me. Great video and looking forward to the review on the pump track bike. Hope you heal up well and fast so you can get back up on that rear wheel!

[@Trenchdigger]

JKW is absolutely correct: CushCore is not for everyone. I ran the CC on my 26" 120mm trail bike for the last 15 months. Yes, the bike felt burlier, and I had more confidence to "let her run" at the bike park. Recently I took the CC out, and ran the same tires at the bike park and trails, and didn't notice any change in grip or performance... and the bike felt more lively without all that extra rolling mass. There may have been slightly less dampening, but negligible. It should be noted that I run my tires at more PSI than conventional "wisdom", within tire manufacturer recommended pressure: 25/30 f/r PSI, and I never have issues with rolling/burping/pinch flats, so there was no benefit there. For those that run low PSI and consistently have tire issues, CC might be an answer. Installation was relatively easy with my rim/tire combo, but removing them was very difficult. My narrow 22.25mm inner diameter rims are at the minimum spec for the CC, and tolerances were tight. I agree that the CC is probably best suited to racers, bigger bikes, and aggressive riders who like to run low PSI. For everyone else, I recommend passing on CushCore.

[@JeffKendallWeed]

Thomas, I wonder if the XC version of CushCore would have been easier to remove from the skinnier rim. But yeah, there are totally some very devout CushCore lovers, and for good reason. Seems like it's best for folks who are having issues with standard set ups, of which there are quite a few.

[@Trenchdigger]

@@JeffKendallWeed I had the same thought regarding the XC version, and may give it a try in the future ... I believe it was not available at the time I purchased my CushCore.

[@JeffKendallWeed]

Yeah it's a new product for them. They also released a gravel bike version, which should be a fantastic application for it! Those little 45c tires need all the help they can get!

[@brandydog47]

I ride the Colorado front range. It is very rocky and running Cushcore in the rear has saved my rim. I went through 2 rear wheels before adding Cushcore. It is a lot cheaper than wheels and very little weight penalty. Also, I haven’t burped a tire since I put it in and I’m running lower pressures that before.

[@JeffKendallWeed]

Right on Pat! It definitely works for many folks, like yourself. It's awesome on the gnarly, steep trails here, but on the mellower stuff, it's less of an advantage.

[@lucashuss640]

I just got some, I ride a lot in mt bachelor area/bend oregon (pretty much lava rock) so I will be using that extra protection

[@lastgentleman8099]

You should try running lighter casing tyres to offset the weight. I find singleply tyres with cushcore to give more grip while still maintaining the support of a dual ply tyre without cushcore.

[@rascal1234]

It might do well on a hard tail. Maybe only in the rear?

[@JeffKendallWeed]

I feel like if you're going to smash into that many things, an FS bike would be better. I like my hardtails light and more XC like, but then again, maybe the XC version of CushCore and some mid weight tires would be absolute awesome sauce on the hardtail.

[@hardtailparty]

I sure like it on my hardtails, especially when I'm on trails that are better for a full suspension.

[@hayeshegemier8091]

I ride it front and rear on an aggressive hardtail, it is makes a huge difference in the ride of the bike!

[@MTBGarage]

I'd argue that you want it more for a hardtail, you really feel the "suspension" effect with it, it wouldn't replace suspension, but it's a nice inbetween. Maybe not for a full on XC rig, but anything you plan to smash some chunk on, go for it!

[@ToshJucker]

I have been running Cushcore in my rear only for about 4 months now and it feels good on very hard strikes and big drops but, very sluggish on mild to all around terrain.

(P.S. im riding a 2020 Specialized S-Works Stumpjumper 29er)

[@imnotacrook5298]

I saw that no one had responded and figured I'd throw in my two cents, for what it's worth. I've never actually heard of someone getting a flat on a Cushcore setup, but I'm sure it's possible. My assumption would be, that you'd need to remove the insert for the repair, and maybe put it over your shoulder like a pack? Honestly, the risk of a flat without the insert is far higher than getting a flat with it, I've run Cushcore for a full year with 9 days at a DH Bike Park on a Yeti SB5 and I've never had a flat. Just a thought, safe riding out there!

[@willbros1499]

From a physics perspective, I don't see how the 12% suspension improvement is valid UNLESS you're running low enough pressures to allow the cushcore itself to absorb some of the energy. If you're running normal pressures, then the tire should still be supported by the air volume. I really didn't feel the ride was any "softer" until I got down around the 22-23 lb pressure point in the rear tire, and that just felt odd to me...like the tire profiled too flat at 180 lbs geared up, and the increased rolling resistance felt very noticeable to me as a result. It's great...UNTIL you have a slit sidewall on the trail and have to put a tube in. It's also virtually impossible to get the tire pushed off the bead to install a replacement without trashing the rim strip, which means cleaning and re-taping is just a given. So real world...what does it help with based on my experiences. 1. In an enduro race, you can potentially complete the stage, albeit slow...even with a full on flat. This coupled with the extra protection against rim/wheel damage is more than enough for a lot of people to run it...and I get that. 2. It will potentially prevent catastrophic damage to your wheel should you get a flat or have a drop in presssure without being aware of it....and hammer into a square edged rock in a rock garden BEFORE you knew you had lost pressure. 3. It will help cornering traction at the lower pressure, but...I also feel like depending on the tire, and finding the sweet spot...it can increase rolling resistance as you ride on the ENTIRE tread of the tire. 4. Not really buying the 12% suspension improvement unless you're a really low pressure, which I think profiles the tire too flat. I honestly didn't feel like my Ripmo felt any "softer" with it in, versus not having it. 5. With a 2.5 Aggressor, I truly felt like the way it pushed the sidewall out, it contributed to two sidewall slits. That could have just been bad luck, but hey...it happened. So.....in the end, I felt like the hassle of installation, virtual impossible task of dealing with it on the trail unless its just a small hole that can be plugged, and the increased weight...weren't worth what I felt like was the one thing that it was providing me, which was protection for my wheels should a series of events occur where I hammer into something with low pressure and crack a carbon rim. In the end...I'll take my chances with having to get a crash replacment rim.

Charles, I actually believe their 12% improvement fully. The insert is pretty big and reduces the volume of the tire quite a lot. In the video you can see my tire hitting the CushCore (I flashed an arrow up) and I have another slo mo example I didn't publish. On both of those instances, I'm landing on a rounded hump, not even a sharp edge like a root or a rock. And at 18 psi, the tire fully hit the CC. The rolling resistance thing isn't that big of a deal, the weight is way more noticeable. A 2.8 plus tire at 14 psi doesn't roll very slow, and it has way more contact patch than a 2.5 tire at 18 psi. I wonder if a wide rim exposed the Aggressor sidewall more than a narrow rim you'd been using previously? I'm 100% on Tough casing (very similar to Double Down) and haven't slashed a sidewall in years. Thanks for the note!!!

@@JeffKendallWeed ... My experience with it was odd. When I got down below 22 psi in the back tire, everything just felt sluggish to me. I rode the stock Aggressor with EXO that came on the Ripmo for a few rides, but swapped it for the DD version and put in CushCore. I definitely noticed the weight, and that could easily account for what I'm saying is rolling resistance...hard to discern those two. It also increased my rebound (lower air volume??). I decreased it a click with cushcore at my standard 27 psi in the rear tire. I played around a little to find the sweet spot for pressure, but having to replace the tire TWICE after that initial one definitely didn't help my attitude toward it, because it's just difficult to deal with. When I smash a rim...and I'm waiting for the replacement, and getting it laced back up, I'll remember giving this somewhat negative review. :-)

Hahaha we'll see! About to pick up the spokes to build those wheels, hope to test in a few weeks.

[@bradywhite520]

A lot of people run it just in the rear, do you think that could be more beneficial for some people or do you think you should run two because it is a system?

[@JeffKendallWeed]

Depends on an individual's riding style! I liked it front and rear. I distinctly remember burping the front Schwalbe tire on the DV9 on steep jump faces; yikes!!!

[@BobBob-fk4wo]

would it be good to run it just in the rear or would it feel strange having it in the rear and not the front??

[@JeffKendallWeed]

I haven't tried it in just one wheel, but I'd prefer to run it in both as my riding style will change slightly when I know it's in there.

[@leonardoolivar]

I been thinking about CC just in my rear, bc carbon fiber rims are 🤑 i don't do enduro or dh just tail raiding So don't mind to add a few grams....

Do you think cush core would help a hardtail?

[@JeffKendallWeed]

According to @hardtailparty, it helps the hardtails in a big way. I'm honestly not sure, I didn;t try that combo. I dont have a trail bike hardtail (yet!).

[@hardtailparty]

It depends on the terrain you ride and your riding style. For sharp edge rocks, and if your hardtail is your only bike, definitely give it a try.

[@davenicholson3491]

Sounds cool. I’m 6foot 2 and weigh 98 kg so any extra “plush “ is welcome. I have 32 mm internal carbon rims, will they work in my rims? Cheers awesome videos dude 🤙

[@JeffKendallWeed]

Yep, 32mm rims are fine, my own rims are 35mm inner width! Thanks Dave- I bet you'd like these!

[@wildearpsadventures4991]

Im about 104kg with 27mm carbon rims. They work great! Initially rear only then quickly did front too. As a heavier rider with carbon rims its definlty a must. Before heard the rim hitting a lot. Now I never do and the traction it provides is amazing. Also great when you do loose air. Happened recently on the rear, noticed it on the climb (had a small cut from a rock). Almost to the top so i kept going. Felt harder to pedal but was determined to get there. Aired back up and it seemed to stay full. Half way down I stopped to check pressure and it was really really low. I didn't notice when it went down except i sliped out on a burm just before.(not that im all that experienced). Couldn't even inagine what would have happend if I didnt have them installed.

[@davenicholson3491]

Wild Earps Adventures thanks man that answered just about all my questions. The only other question I have is can they be reused once your tire wears out? The sealants gets real sticky like glue. Will the cush core be glued to the old tyre? Thanks for your reply dude🤙

[@wildearpsadventures4991]

@@davenicholson3491 reusable for sure on 3rd tire. They do wear out supposedly but not sure how to tell.

Not currently- pelvis is too broken to get rad. BUT, I've got plans to get back on that bike soon!

If someone will install it for me and I won't have to climb hills with it , then sure, why not!

[@josedavalos1223]

I don't recommend cush core, too heavy, feels flat tire and poor speed rolling. I had terrible accident using it while jumping on a downhill track. My opinion use a good tire with tubeless. Or use Mr Tuffy band with regular tubes.

[@themtbguy9496]

Jeff, are you running it front and rear?

On the Ripmo, yes, was running it front and rear.
