[Closed] Schwalbe ProCore - anyone ridden them?

Oooh! Where did you manage to pre-order?

I cannot remember the last time I was this excited about the lastest big thing!

(I don't know whether you can get away with a narrower rim that Schwalbe suggest. Personally, I'd take the opportunity to upgrade your rims while you're waiting for the ProCore to arrive...)

🙂

I reckon you'll struggle to physically get everything into a 19mm rim, that's nearly 20% smaller than their requirements. Worth a go though.

They're available to order through 18 i think ....£157 though !

Nextdaytyres too...

Funny enough I pre ordered a few for the shop yesterday, (26 & 27.5) I think (not 100% sure) they limiting them to Schwalbe LBS Dealers who do the Road Tubeless tyres shops.
I need to find out more.

If anyone having trouble ordering them let me know sure we can sort something out, Procore kits due in April, I think there going to hard to get hold of to start with (just like road tubeless "Ones")

I was pretty excited for Procore when they first announced it ages ago.

Am I right in thinking it's now just 1 valve so no need to get the drill out? If so even better I suppose.

Am I right in thinking it's now just 1 valve so no need to get the drill out? If so even better I suppose.

yes. Saw it at the Core Bike Show and had it explained to me by the rep, and the single valve was a big part of the development, patents etc.

The new single valve changes everything. Last time I saw the system it had two valves and I didn't want to take a drill to my Flow EXs.

200g is quite a lot of weight per wheel still.

On all the different tyres I've tried with tubes or tubeless the only issues I've had have been on the rear. Snakebite with tubes, burping with tubeless, and unsealable sidewalls from rock cuts. All rear. Fronts run 20-25PSI tubeless with no problems so far for me. For Trails / AM the rear needs 28-32 to be sure (but 40PS at Antur Stiniog to survive).

I currently run Hans Dampf Snakeskin 2.35 Trail Star tubeless and they're amazing tyres.

It's almost worth the weight penalty on the rear to not have any worries at any location.

Has anyone reviewed the system yet? Setting up Tubeless is already quite a faff. Can imagine this being even more of a disco dance.

Nextday tyres . Great service from steve here, guarenteed.

But they didn't get a look inside, so nothing about fitting.

Thanks brennanpj and Clobber - on it!

😀

I'll be doing this once the cost comes down, it will make it possible to run silly thin walled Maxxis tyres tubeless and with low pressures without the fear of burping, tearing etc....genuinely great idea and the inner core/tube pressing the bead of the tyre against the inside of the rim should make them a doddle to pump up tubeless and with a perfect seal every time.

Are you going to stop and pump up your tyres after every technical section or pedal about with 15 psi? Also having my sidewalls flop about and flex through corners is not something I'd appreciate.

Might be a worthy addition for high level dh or enduro racing where a puncture won't mean the end of the day but I can't see me needing this for recreational riding.

We shall see. Tubeless is better than tubes. Low pressure tyres are ace. Choosing between slightly too much air or horrible banging sounds from the rear rim is a drag. Worth a try. I am EXCITE 😀

no one wants to hear horrible banging sounds from their rear end.

I might be a late adopter on this system, tbh, other than my fat bike I like to run pressures that I can do a bit of everything on so silly low pressures and associated drag don't appeal too much and I don't have problems with tyres rolling off rims or rims dinging on obstacles.

Might be a worthy addition for high level dh or enduro racing where a puncture won't mean the end of the day but I can't see me needing this for recreational riding.

I'm looking forward to it so I can ride with less than 35 psi in the rear tyre (with a full suss and exo sidewalls) without destroying rims... like tyre choice it all comes down to where and how you ride as to how useful something is. Going by the last 2 years of riding I'll save that money soon

but I’ll put money down now that this time next year everybody except XC racers will be on this, with other manufacturers desperately trying to play catch up, or copy cat.

4 months to go until we're all on this 🙂

I already run very low pressures (around 18psi), so I don't think I'd go much lower, but it would be nice to feel invincible from punctures and rim-dings.

Whenever I use my DH tyres with thick innertubes, it's amazing how it influences your riding - you can just ignore so many more rocks and focus on lines instead.

I reckon he gets an extra few months, given the production delay.

I think anyone riding dh or enduro at any level will be using them. With entry fees as high as they are it's not really that much money to stop a puncture spoiling your day.

ftfy with regards to off road sportive riders 😉

I race DH & Enduro and won't be bothering with it.

I can't see the point. Low tyre pressure feels nasty when you load the bike up in corners.

I've had one puncture in about 3 years. If I want to add weight to my wheels & reduce the chance of flatting, I can chuck a DH tyre on the back.

The outer air chamber is effectively like a tubeless tyre?

Anyone else seen this;

If you don't purchase procore from, and have them fitted by an approved centre (bricks and mortar); no warranty. **** knows what happens if you want to change a tyre.

It doesn't exactly say that only an LBS can fit it; it says you can only buy it from an LBS, and that they have to fit it. But nothing about subsequent use. Small distinction I know but maybe matters.

I dunno, that's what I assumed but I'm curious how the combination of high and low cells, and the lower volume of the low pressure part, all adds together. Not that I'm going to pay a hundred quid to try it

Doesn't the whole 'contract is with the retailer' kick in though so if you do have an issue the product you'd bought from, for example, nextdaytyres, you go back to them

The practicalities will shaft them anyway. Are they going to keep a record of the tyres they fit to each wheel/bike? When you drag in a shredded procore they aren't going to know if it's been refitted or not.
Stupid idea which will die.

If you have a tyre with a stiff sidewall like the Maxxis EXO and Continental Protection I find them nice at low pressure. However others like spesh and Schwalbe tyres are very squirmy at low pressure.

The volume of the low pressure bit is smaller so it will deform to conform to the ground but not enough to squirm about. I thought of a similar idea with closed cell foam in there instead.

So basically we're getting excited about fitting a heavy, very expensive tube to a tubeless tyre?

Nope epicyclo, not sure you understand the system.

Like the sound of it, but like others I will be waiting for it to be a sensible price and to have some real user reviews rather than mags and fan sites.

Anyone thinking they are a good idea for xc racing, in particular longer races? My only problem with tubeless is sidewall tears. I've tried snakeskin schwalbes and that made no difference so back to standard and hoping to avoid flints

I'm keen to give it a go, it is a fantastic idea imo.

I have a set of LB carbon rims, the older ones which don't have a lip to hold the tyre bead in against the hook. Because of this, they are very burpy tubeless and I'd givn up on them. The procore 'tyre' should lock the tyre against the rim and sort this out. It's pricey, but cheaper than investing in another set of rims.

You realise the hookless rims are the latest ones, not the old ones...

I'm assuming the outer air chamber is tubeless, if so how do you get sealant into it? No sealant means the slightest nick will deflate the tyre. Also running lower pressures will increase the likelihood of ripping the tyre and increase tyre wear, plus it's a schwalbe so it'll last about 6 weeks anyway.

Hypodermic needle and syringe? Inflate the tyre, then inject it in. This also tests if the sealant is any good...

Or, you know, just put some in the tyre before mounting it?

If I was riding / racing a lot of rocky dh
stuff
But I have not had any problems racing enduro with exo maxxis on lb hookless rims

I did tear a tyre at the Megavalanche this year so it's something I'd consider for that sort of riding but not at that price !

I do, but fail to see the advantage to a practical cyclist, especially considering the price.

However I have had good results with Schwalbe tyres, so I'm sure it works.

I'd love to try this - pinch flatted tyres and dented rims are female dogs. If I had a 29er I'd probably just buy a tub slick tyre and use a needle to inflate the outer chamber but since I don't I will wait for more feedback and possibly alternatives (DeanEasy looks good as well).

Read my post.

Mine have a hook, but no lip. Newer ones have a lip, but no hook.

Also running lower pressures will increase the likelihood of ripping the tyre and increase tyre wear

The exact opposite is the case though.

Running low pressure for any length of time will (in my experience) result in cracking and splitting the sidewall, compounding the problem of the tyre squirming under load. It dramatically shortens the life of a good tyre, never mind a Schwalbe.

I've ridden the system. I ride 6 months of the year, pretty much every day in Lake Garda as a guide, extremely rocky technical terrain. I need a system that works and is reliable. Simple. I run at 14/15 psi front and 20 psi rear. Schwalbe tyres, Syntace rims. Sometimes down to 12 psi front. No burping, no flats, no rolling. Amazing grip. A few KoM's going down and set some of my fastest times going up. I'm never going to get a KoM going up at 54.

I first saw the system over a year ago at the Syntace factory.

Low tyre pressures use less pedaling effort uphill than high pressures. The science and facts are out there to be read, but most are in denial. Rolling resistance is what is quoted by tyre companies and that is measured on a rotating drum in a lab... nothing to do with energy used mountain biking unless you ride on tarmac all the time.

If you try and run low pressures with rims that are too narrow that is going to cause problems, see the article on pinkbike - http://www.pinkbike.com/news/Tech-Tuesday--Wider-Rims-Are-Better-and-Why-Tubeless-Tires-Burp-.html

I've never felt as confident and as safe on a bike since using lower pressures. The procore/syntace/schwalbe combination is the best wheelset I've used by far.

Pricey? New stuff always is, I've seen the R&D put into this first hand, Syntace are a relatively small company. It will become cheaper I'm sure in time, as with everything... but then there will be another improvement on the horizon perhaps 🙂
