I've learned after being on a 29'er that they're simply too lazy, too stable, and basically boring. Wide open Arizona, California, Utah? Of course!! But for my slower terrain, yeh, too boring.

On my 27.5 I love the peppiness, the playful BMX'ish vibe, but ultimately they're a hair too small and slightly sketch for my 6'1" frame. So I have come BACK to the 27.5+ tires and deer gawd I've missed these!!! (used to have a Specialized Fuse).

I've recently also come back to a hardtail (Trek Roscoe) and loving it. Just wondered what the consensus on Cush Core was? I've watched a few "sales pitch" vids, but wondered about the real world answer. Wanna try them out but only thinking my rear tire.

@Markhat250 26" isn't quite dead yet, and it's kind of better for the stuff that destroys other wheel sizes when it comes to MTB's.

As for Cush Core, never used them so I can't add anything.

Pity there's no search tool on the forum, as I do remember that there was a thread a while back where they were discussed.

I run 27.5 X 2.8 with Tannus Tubless Armor in the rear on my Norco shore and it’s great. Cushcore is to heavy and only works to slow rim impact in the last few MM still causing a big jolt. I Run 190/190 travel and a 2deg angle set. It can handle super steep trails, big drops and high speed rock gardens and then climb back up to do it again.

I have CushCore front and rear on my Chromag Stylus.... It takes some of the chatter out on a hardtail,also allows lower tire pressure and stiffens the sidewalls of your tires so you don't burp air when carving corners with low pressure. sure they aren't super lite but they are worth it to me. I've ridden 20 plus years without them and I can't imagine going back to basic tubeless now after having had them over 8 months now.

I have to limit myself two nice bikes and even sold the last 27.5 to help finance my Chameleon. After being all 29er, which I do indeed enjoy, I am missing the ride of a 27.5.

@Markhat250 there's definitely some truth in that "lazy" feeling to the 29ers I think I know what you mean. I ride XL frames and I noticed something that's missing--especially when pedaling over the nasty rooty-rocky terrain of these New England woods, the kind of "feedback" I'd get from a 27.5 is lost. I felt more connected to the terrain. There was a more organic experience to the ride than there is with my 29ers as strange as that sounds.

When I got the Chameleon as my hardtail, I rode the mullet version and almost went for that instead because I felt a little more of that w/the smaller rear wheel. Interesting, and I admit I didn't think at first I was going to miss that LOL

Yeah all those Marin full-sus bikes look real nice. Kind of remind me of some Treks, but the Marins look more "monster-truck", a little tougher lookin' frames maybe than some of the Treks. I like them

Keeping it in good shape there. That bike still looks new.

Short leg guy here that likes 27.5 for rowdy riding ... Ibis Mojo HD5. I have a 29er Ripley for trail riding. If I'm in the bike park or racing enduro where I'm more dynamic on the bike, I need the extra 1 or 2 inches between the wheel and my butt.
On CushCore ... never used it, but I do run Rimpact. Rimpact is lighter and works great for me. I don't know about running lower pressures (I don't think mushy tire = more traction), but they have softened the impact on my rims when impacts get sharp. I've also been able to ride out of a trail on a flat tire without the bead breaking. The downside is changing tires. Mounting new tires is extra work, as expected. Breaking the bead of the tire you want off the rim is a beat down.

Well, any insert is expected to make some things a bit more work. But at least you know it's working I guess. I looked up that "Rimpact" you mentioned--a lot cheaper than the Cushcore, even for the SET! I'm going to consider these on my 29er Stumpy. I was going to possibly put in the cuschcores, but after seeing these, if I do it, I'm going to get the Rimpact.

Thanks for the tip tup

-Definitely! If you ride in terrain with sharp rocks and experience a lot of rim strikes already, definitely go for the Rimpact Pro. If you ride mellower trails and just want some support and some rim protection, the original might work. I will say that these inserts to make the tires feel a bit wooden until you're up to speed. Not sure if the CushCore does that too.
Here's a good comparo: http://https://www.pinkbike.com/news/review-6-best-tire-inserts-2021-ridden-rated.html

Yeah definitely. My Stumpy is what sees the worst terrain and that's the bike I was thinking of putting these in. Already had ONE rim flat that took two Stan's Darts just to hold pressure for a day (since have repaired that tire).

I checked that article out: https://www.pinkbike.com/news/review-6-best-tire-inserts-2021-ridden-rated.html
This looks great. I ride with a firmer progressive suspension and I typically like a firmer tire that sometimes feels a just little rough to some riders, even with my carbon rims on that one. My hope was to TRY an insert and see if I could go to lower pressures and still feel a little stiffness in the tire? Worth the try? But these Rimpact inserts are looking better to me than the cushcores.

I wanted to throw those caveats out there. It sounds like they're right up your alley. I 100% recommend trying the Rimpacts.

Can't believe I forgot this...
I also have good experience with Vittoria Airliners. Even though it fills more volume of the tire, it doesn't feel as firm as the Rimpact. Still good protection and support.
Here is the downside: I have not run it on a flat tire. I don't think that it would keep the bead seated as well as the Rimpact. The Rimpact is 1 piece, the Airliner is cut-to-size and and then joined with zip-tie. The material where you use the zip-tie can stretch just a bit making the liner loose in the tire ... and noisy. It still does its job with support and rim protection.
Summary:
The Airliner is a more comfortable ride at less than race speeds, but still provides good rim protection. The Airliners are available in several sizes for larger tire widths. They can be noisy.
The Rimpact changes how the tire rides at all psi, provides good rim protection. They have been completely quiet in my experience.

You’re not alone. I’ve only been riding 3-4 years or so, but I love the 27.5+ as well on an old Roscoe. I have a few other bikes, one 27.5 and one 29er, both full suspension. And so far I highly lean towards the smaller wheels. Part of me would love to sell the Roscoe, but it just puts a smile on my face after riding it. Highly recommend a trek superboost? Hub in the real. Thing screams and has great engagement.
