[Closed] Just fitted cush core for the first time.

In my limited experience it can be breaking the bead free from the rim when you want to remove the tyre that the fun starts.  Really depends on your rim/tyre combination

Cushty 👍

Yeeah I can get a proper sweat on trying to break the bead and/or get the tyre over the rim when I need to remove it, that's with Rimpact.

What I can never understand is why all these tyre inserts are obscenely expensive, for what they actually are.

I think it's basically harder to describe than it is to do, that whole "sort of push the tyre under the insert" thing. My hands can do it no bother and I can show people, but I don't think I can explain it well enough for it to be useful.

That's why I'm promoting the idea of watching the video as you say obvious once you've seen it.

Just had a look as apparently I’m out the loop. Looked at Rimpact and thought it’s expensive foam but ok, then looked at Cushcore, then stopped looking

Because why would you bother manufacturing a product and selling it for the lowest possible price rather than the highest?

“ What I can never understand is why all these tyre inserts are obscenely expensive, for what they actually are.”

Some years back I spent quite a while working on a potential product for tilting and mechanically isolating bass cabs from the floor, made from foam. The problem was that the raw foam was amazingly expensive and so was the processing cost. There was no way that we could make it profitable when selling it at the higher end of the maximum perceived value.

Foam products seems like they should be cheap but a lot of types of foam really are not. No-one is getting rich selling foam inserts for your tyres.

I put Rimpacts in one bike about two years ago and in the other bike a few months later.

I got a ratbite for my rear a few months ago (www stopped working now). Seems to depend on the tyre as to how easy it fits.

Aldi caravan awning interlocking floor matting..... 6 tiles for £12 - 2.5 cush-core type tyre inserts from each tile = 80 pence per insert (I call them Cwtch-cores :-0 ). I am now on the second one in the back of my main bike. First lasted 18 months or more but was pretty indented when removed. It had certainly done its' job.

I did a post on this forum somewhere with pics.

^^^ that really isn’t the same thing. Maybe similar to the hucknorris but a cushcore is all about sidewall support at lower pressures. BThe tannus ones are supposed to be good as well as being easier to fit/remove and slightly cheaper. I like my cushcore in the front on the full sus and both ends on the hardtail, worth the money for me and not an issue to fit or remove with the right technique.

Did you ride on any of them?

Rimpact is one of the best upgrades I've made since tubeless and offers two distinct benefits: Rim protection (saving me £££) and extra damping - allowing me to ride faster and the bike to handle more predictably over rocks.

And it lasts ages. One is probably in its third tyre now.

Good to know - i have just fitted rimpact - first ride this weekend on it, looking forward to feeling the difference.

I would say that one of the things they're good for is racing, so you can ride on with a flat to the end of a stage, but that kills them pretty well. Sort of the equivalent of a foam snakebite, they get covered in holes and bits break off. Doesn't have to be a total flat, even riding on a slightly too soft tyre beats them up very fast (a friend damaged his badly while experimenting with tyre pressures, he went a wee bit too low but still in "I think this rides OK" territory and that was enough to chew chunks off it)

Which is absolutely fair enough, and better than a mangled rim or stopping on stage, but maybe worth bearing in mind for longevity.

Really? - I rode 2-3 miles home on mine last Saturday as got a gash in the tyre, Rimpact came out as good as when it went in.

My rimpacts finally delivered on what tubeless always promised - really can use tyres at a low pressure without wincing every time your rim gets dinged and without the tyres getting all squirmy. I absolutely love them and would have another set in a blink of an eye. My DH bike and my trail bike both have them and I think they're fabulous things and so much better to ride than just having tubeless tyres, though I notice the support aspect a lot less on really thick DH casing tyres, admittedly.

I have used Rimpacts since they first came out. The damped feeling is there and there is no question they protect the rim. All my enduro/am bikes have had them. Recently though I removed a pair from my Rune V3 and put my pressures back up to 23F/27R as opposed to 22F/24R with the Rimpacts. I just found I have been riding better with the higher pressures and no insert. There was plenty of sidewall support with 2.5" tyres down to 22psi on the rear but it just felt off.

I am tempted to go cushcore but with heavy enduro casings I think I will hold off for a while until I actually have a puncture.

What sort of riding though? One thing using it as a handy way to limp home, another to be riding normally on it with low air.

Love my rimpact too, had to clear a massive rubber sealant gunk ball from the rear tyre the other day and found there was only a couple of rim indents in the insert, I'm obviously not riding hard/fast enough...

I use around 22/18psi front and rear, in a 2.35/2.6. Got a set of rimpact std and pro for the new hardtail build. The valves are excellent too.

To be fair, the Rimpact inserts do seem very reasonably priced - I’ve ordered a couple to try anyway.....

Cushcore weighs a ton. I found it gives loads of traction but tipped my wheels beyond critical weight.

Uplift only

I picked up a pair of cushcores at the same time as my buddy, his arrived quicker then mine, we watched the video and tried fitting and it was an ache! So much I never fitted mine, saw this video from Jess Melamed yesterday and it has a slight different technique for fitting which looks so much easier!
