Cush Core Tire Insert Review at

Cush Core Tire Insert Review

Initial skeptics to tire inserts in general, Cush Core has made us into converts. These are tire inserts done right.

Constructed from closed cell foam to avoid soaking up tire sealant, Cush Core offers a myriad of benefits for your tubeless mountain bike tire set-up. You can run lower air pressures, thereby increasing traction, without increasing the likelihood of rolling or burping your tire. It also has the unique effect of drastically reducing overall vibrations, as well as dramatically reducing the chances of a bent or cracked rim. This means less money spent replacing dented alloy rims or expensive cracked carbon.

NOT COMPATIBLE with the following rims:
ENVE – the valve stem isn’t long enough


Angelo Blanda says:

does it fit 27.5 plus tires ?

James Brant says:

$250 in Canada. no i’m not kidding.

Zac Youngson says:

Just use swimming pool noodles, slice em down the middle, join with zip ties, makes a huge difference to grip and handling and only $4. Thanks for the idea cush core !

MTNcorps says:

I just got these. They are outstanding

Jurica Grčević says:

Anyone tried adding water pipe insulation inside a tubeless setup?

The FPV Life says:

So overpriced. Robbery. Go to home Depot n get foam pipe covering n cut to fit.

Ryan Forsyth says:

These things are awesome, they’re way better than all the other inserts on the market. The actually put pressure on the entire bead and the foam is sealed so they absorb way less sealent. I know there expensive but there is a lot of r&d in these and they transform the ride.

BryantKHill says:

I have a set and I haven’t made up my mind on them so far. They do help with grip and I like having rim protection. My caveats are that the stems are a little too short for my NOX Farlow rims and I fear that it doesn’t seem like it will be fun if I get a flat on the trail and need to install a tube.

Great review as always! Keep up the great work!!!

Derek Mckee says:

$150 to protect my rims from the super rocky terrain, you bet i’ll order a pair.

armourbl says:

With regular tubeless, you can still throw in a tube if you get a bad cut in the tire. What do you do when there is a foam insert?

Dominique Bashizi says:

Off the subject, but the presenter is the first person I see talk about mountain bikes who has dreads. I just got box braids with extensions and I cannot fit into any helmet I’ve tried. Do you have recommendations on getting a helmet big enough for a 27″ head circumference? I’d even consider custom options but can’t find anything. Any tips would be greatly appreciated!

RoboticusMusic says:

Procore is lighter and cheaper and is an actual tube, not some shitty piece of foam. Procore does the same thing with tire roll.

William Gable says:

Just run closer to recommended tire pressure

Mia Fuller says:

Throw in some extra cush and I’ll pay the $150

Brendan Tovey says:

Hmmm … really interesting. Do you think or have you worked out whether what internal rim width you run makes a difference?? I’m kinda thinking this must play a part in this set up as folks could be running in the range of 25 – 33mm+ which is a big range ??

Fanatik Bike Co. says:

Ok guys,
I will be the first to admit $150 is a lot of money for “foam” inserts, and I was very, very skeptical when they first came into the shop. After seeing a couple of the guys at the shop put them in on their hardtails and ride down some of the gnarliest rock gardens I have seen, with only 17psi, and having no issues I have got to say I am very interested now. The way I see it, if you can take a bit of a weight penalty but gain a ton of performance and protection for your rims that may have cost $2000, why wouldn’t you?

Le Germain says:

So this simple piece of foam costs more than a set of high performance tires? Nuts. Say it costs $30 for a set of two I would consider it ok, but for $150, never.

caleb marr says:

Would you guys recommend just running one in the rear wheel or both?

Lughnerson says:

That was a very good review.

Mike Thomson says:

As someone who’s broken 2 rims this season and 1 last season I’ll be ordering a set dispite the steep price, this looks like the best thought out of the options available but half the price would be reasonable.
I’ll comment more after testing

Sammy Oofol says:

material cost is less than $1…. Im not a weight junkie (my bike is 16kg) but with a DP tyre of roughly 1.2kg adding another 270g is credulous to me…

BuckeyeMCS says:

$150!!! No way.

Joe N says:

$150 for a piece of foam?! Just like a plastic resin bike called ‘carbon fiber’ costs 4 grand. Both are marketing bullshit. Suckers with money burning a hole in their pockets would buy either……ha ha omg a piece of fucking plastic in a tube. Come on!

iguanabartola says:

Great review. Have you experienced any flats as yet? Thinking on the process to actually remove these on the trail and having to install a tube!

cellphonenut says:

Touched on all the main issues great review

James Brant says:

thanks for the review Fanatik. question, do you feel the weight of this set up much? are you quite aware of the added rolling weight after installation and do you feel it when climbing? if so, do you feel it’s worth it for the added performance?

Steven Mullins says:

I’m destroyed from installing a pair of CushCore inserts into some i9 Enduro rims with Bontrager XR4s yesterday. Literally the hardest install of anything on a bike in decades of wrenching.

BUT, on two pretty techy rides so far, holy crap they ride well. The cornering and drops feel distinctly different. Really curious to see how much these improvements outweigh the weight penalty. I have a couple enduro races in the next month so I’m hoping these will really help with squirm in the cornering and control coming off of jumps and drops.
