You’re probably familiar with CushCore by now, so have a look at all the details over at Jenson USA here: bit.ly/CushCore2022jkw (affiliate link)
I’ve heard about CushCore for quite a while now, but my big, burly two ply WTB tires haven’t really left me wanting to try out any inserts. The hefty tires provide lots of support and do a great job of resisting flats on their own. CushCore was nice enough to hook me up with a few sets of their product, and I threw some into the Ibis 942 wheels on my Ripmo 29er.
I did notice the weight- like I just mentioned, I ride very burly tires at 1250 grams a piece. Adding the 250 gram CushCore and my rotational weight is now over 1500 grams. That’s more than some complete wheelsets! However, once I got used to that extra weight, I did find many situations where CushCore offered a very real benefit.
I am not going to put CushCore on all my bikes, but I will definitely run it on my long travel bikes, and I’m also going to expirement with it on my dirt jumper and trials bikes.
Big thanks to these guys for making this all possible! Any purchases from these links will directly help support this series as well:

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.
I ride a fully rigid 29er with Cushcore front and back. They make me smile. A lot :)
Right on, Robert!
Me2. Titanium frame & carbon fiber rigid fork city riding city streets tubeless & cushcore
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.
How much lower do you go on pressure when running it vs without?
@@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.
@@hardtailparty Thanks for explaining the damping effect. New info to me.
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.
112% of zero is still zero :D
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.
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!
@@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.
Best explanation I’ve heard yet!
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!
Glad you like them, awesome review with a spot on explanation.
Thanks Andrew!
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!
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!
Thanks for thoughts on CushCore and I agree it’s a good move for big riders
Thanks for the no bs review. I always wanted to give CushCore a shot.
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.
Been running cushcore for a month and my tennis elbow is going away.
Might sound dumb but what do you mean by tennis elbows
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!
just installed a set ,love them
Enjoyed the video! Get well soon!
Thanks Ivan!
Nice review and riding!👍🏻
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.
I have cushcore in my Bronson with Santa Cruz Reserve rims and absolutely love it.
Boom!!! Thanks Vin!
I love my cushcore insert. I blew threw 3 spank rims last season and after putting in cushcore I have had zero issues
Right on Luke!
Yo tough casing wtb tires are the bombbbbbb. Keep plugging them
Cush core on both my bikes. I love it.
Right on man!!!
dude wtf!!! that rock roll (rock huck???) at 4:55 is no joke! my first bellingham rock roll and i rode my brakes down the whole thing hahaha
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
Thanks for the review Jeff, I’m definitely feeling inspired! I’d love to hear more about your Cush core/pump track bike experiment 🤔 and also, considering IBIS doesn’t make a DJ, what exactly is your pump track/DJ rig? Keep up the good work and best luck with your recovery!
I noticed the difference on my Rocky mounting Powerplay when going down rock gardens, before it was a very stiff feeling and jolty, the first time with them in it felt so much smoother.
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
I like the wide rims too!
The wide rims are great for *most* tires. I'm a little concerned about how square the Ikon 2.2s will be on the Ibis 638 rims on my DJ bike, but hey, it's only an experiment away!
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!
Great initial explanation!!!! A lot of people don't get what cush core is really about/
Yeah we'll have more content coming out on CC's channel that better explain it, too! Thanks Thir!!!
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.
I'm going to try them with 2.6" rekon f and r. Much lighter tire to compensate for the cushcores. Those tires should work well for my local trails. Hopefully it works out, waiting on a broken femur to find out.
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
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.
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!
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.
Interesting never thought about the offset rim effect on inserts, especially CC. Glad I chose the Vittoria Airliner. Good review
Thanks legend, i haven't tried the Vittoria product but have heard good things!
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...
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!
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 :)
Right on Bryan! It'd be cool to get some of those lighter, smaller CC and compare them to the full on version.
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.
I run cushcore on the rear of my hard tail cuz I’m about 240lbs and need DH tires with thick sidewalls to avoid burping air. Seems to be working so far
Right on man!
Just put Cushcore on my HD5. Yes, it was a pain to put on. I did my front, but ended up damaging my rear wheel. It was may fault, though. Ibis replaced my rim for free. So, 👍to Ibis. Haven't taken it out on a ride yet. Hoping it helps with my RA.
You should put it into your Stylus chromag I found cushcore a beast when you are using hardtail and jump and do drop over 2.5 metres I found it really good
It might do well on a hard tail. Maybe only in the rear?
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.
I sure like it on my hardtails, especially when I'm on trails that are better for a full suspension.
I ride it front and rear on an aggressive hardtail, it is makes a huge difference in the ride of the bike!
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!
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.
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.
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.
The offset well on the ibis rim is not very deep need the far side. It gave me a lot of trouble too. The sc reserves were a breeze.
I love my cushcore, but I'm racing the downieville classic this weekend and I switched to narrower tires and no cushcore to save weight and it feels so much easier on the climbs now. But on the descents I miss the grip!
Yeah, for racing D-ville I'd say go as light as possible, except definitely run Tough casing tires!
Jeff - you mentioned a trials bike. Do you have any videos showing you riding the trials bike?
Does the cush core become soft and easy to rip apart after some long time miexed with Sealant ? Btw, just subscribed, keep up the awesome work !
I haven't heard of it having that issue. It was launched in 2017, I feel like if it fell apart we'd have heard of that by now! Thanks Nicky!
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.
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.
@@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.
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!
I think this would be nice on my Salsa Timberjack with 27.5+. I keep denting the rear rim.
These would work awesome on a plus size bike- especially if you are riding a lot of rocks!
@@JeffKendallWeed I am. Lower pressures on a hard tail make for great control and traction, but I'm ruining the rim...
What your opinion on using Cush Core for an aggressive hardtail with 130mm up front? Would it help just having the rear with the insert? Or both?
I really really need to get some being a big dude that tries to shred im constantly getting burp flats (is that a thing?) when I corner even though I pump through corners. I think a lot of that is due to my rim width on my trail bike but I think this may allow me to shred a bit harder without burp flatting.
Man, yeah, you'd likely benefit a ton from CC! Take a look at how many CC lovers there are here in the comments.
Is it compatible with tubes? Or would something like Tannus Armor be better in that case?
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....
I have an hardtail san Quentin 3 I love it but I'm also destroying every bloody rim. The sq3 is very capable do I feel like I can send anything and I do but my rear wheel is paying an hard price for it. I think cushcore could help on a hardtail?
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. The bike feels like it does not create forward momentum. Id say its an okay system for people riding gnarly more downhill trails not light to medium trails. (P.S. im riding a 2020 Specialized S-Works Stumpjumper 29er)
Yeah Gage, for super rocky trails it's awesome, and for super steep trails it's awesome, but for mellower, rolling terrain, I don't feel it's necessary.
Had a question and concern about the CushCore. I'm riding my Mojo 3 with 2.6 tires (Ibis Carbon rims), more of an intermediate rider at about 210 lbs. Would you advise me to run CushCore? big concern is getting a flat on a tire with the CushCore and trying to fix it, assuming it's not something I can plug.
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!
Interesting you'd address this today - just *yesterday* I was schooling myself on tire inserts and decided I'd try Huck Norris first due to their insignificant weight factor.
Interesting! I know nothing about the Huck Norris system but will have to try it one of these days!
@@JeffKendallWeed You mentioned you didn't want to ride any inserts on your other bike, what was it again, I can't recall, a tricycle maybe, anyway (lol) you might try them in that since they basically feel like they don't exist but still help avoid pinch hitting
@@JeffKendallWeed Sorry, pinch *flats*
what about on a hardtail???
Lair of the Bear step-up?
Hey jeff what do you think of just using half a poolnoodle instead of cush core?
I haven't tried it myself. I'd be more inclined to just do it the right way, and use the product that's engineered specifically. After seeing how CC selected the foam compound they did, I believe in it.
Jeff, how about on a hardtail?
I picked up my new Ibis DV9, running Maxxis 2.5’s.. rear only or both?
Danny H I run it rear only on my honzo and it feels great so far
The Honzo looks awesome! That's a cool bike.
Danny, I have no experience with it on a hardtail, but @hardtailparty has reported that he LOVES it!
@@JeffKendallWeed my wife has a dv9 and she will be putting the xc cushcore in her tires soon.
Right on! I want to get a DV9 one day, that bike is neat. Gotta save my $$$ up, got some big medical bills to pay first!
I would like to see a trialsy hardtail video Jeff. Would you be up for this?
Not currently- pelvis is too broken to get rad. BUT, I've got plans to get back on that bike soon!
HD4 a small bike? Mine still feels HUGE with 36 fork and 742 rims.
Made it into the vid. Sick!
Hahaha thanks for the comment man! Wasn't sure how to pronounce your name though!!! Hope I didn't butcher it too bad!
@@JeffKendallWeed dont worry your pronunciation was on point. Great video
@@JeffKendallWeed dont worry your pronunciation was on point. Great video
Right on! Have a great weekend!!!
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?
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!!!
can you get the Vigilantes in 2.3?
Cushcore with exo or thick DD casing? 230lbs Enduro rider on carbon wheels.
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??
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.
I see at 2:52 that you're still running 26" eh? 😁
Yep, on both the DJ and trials bikes.
@@JeffKendallWeed Well that makes more sense. I was thinking your ibis was running 26 and I was like huh?
I wasn't impressed with Cushcore. I run 2.6 WTB tires so I didn't notice a suspension gain. I did get a pinch flat and found it hard to find the right PSI in my tires.
Fair feedback! Were you using the plus version of CushCore or the regular? I've been thinking about some 2.6 tires on a DV9 hardtail, though not sure if the DV9 could fit an aggressive 2.6.
@@JeffKendallWeed I used the standard size based on what their site recommends. My rims are 31mm so they suggest the standard size.
Bummer, sorry to hear that it didn't work out for ya! Reading through the comments here, there are a bunch of CC success stories, but also a few folks (like yourself) that ended up going without. Interesting how it's awesome for some and not needed for others!
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 🤙
Yep, 32mm rims are fine, my own rims are 35mm inner width! Thanks Dave- I bet you'd like these!
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.
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🤙
@@davenicholson3491 reusable for sure on 3rd tire. They do wear out supposedly but not sure how to tell.
Wild Earps Adventures cheers🤙. Will be getting Cush core now. Thanks for all your info dude!!!

Do you think cush core would help a hardtail?
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!).
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.
Jeff, are you running it front and rear?
On the Ripmo, yes, was running it front and rear.
@@JeffKendallWeed you said "was" lol double down tires feel better for you?
I'm not running anything currently besides a couple of crutches! Got a few more weeks till I can ride again with this broken pelvis. I do really, really like these WTB Tough tires though.
@@JeffKendallWeed ahh yes, forgot about your accident. Hope recovery is getting better. It's been about 2 months since my accident and no signs of me getting back on trail anytime soon :(
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. :-)
If someone will install it for me and I won't have to climb hills with it , then sure, why not!
Is it just me, or does this guy always sound like he's trying to impersonate Billy Mays?
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.
Don't ride parks and pedal my bike 100% of the time so cushcore would be added rotational weight. No Thanks! Keep up the good work Jeff!
Fair feedback! FWIW, I have only been pedaling that bike with the CushCore, but I pedal it to some really steep, really gnarly stuff. Thanks man!
less jump cuts the better! Try one take!
Thanks for the feedback!
