First batch of Schwalbe Procore shipping, shortages expected

With the Procore double chamber system mountain bike tires can reach completely new levels of grip, control and puncture protection. In the inner chamber there is high pressure, and with 0.8 bar in the outer chamber the tire almost "sticks” to the ground. Both chambers are filled with air through only one valve.

Off road, riding at lower pressure means better performance but at the same time it increases the risk of failures. "The limit so far is at about 1.5 bar, below which it’s hardly possible to dare to ride normal MTB tires”. explained Schwalbe chief developer Markus Hachmeyer.
With Procore there is now the possibility that the air pressure can be controlled in the tire‘s double chambers. The inner chamber consists of the inner tire and tube with the patented dual valve. It is inflated with high pressure from 4 to 6 bar. The outer chamber on the other hand is tubeless. It consists of a standard tubeless compatible MTB tire. It is filled with a little sealing liquid and very low air pressure of 0.8 to 1.5 bar.

The effect is spectacular: The high pressure inner chamber almost completely eliminates the risk of punctures. At the same time, the inner chamber secures the tire on the rim. This means that you can ride with a much lower tire pressure in the outer chamber and significantly improve grip on even the roughest terrain. With one Bar air pressure, the tires almost "stick“ to the ground, and give the bike much more grip and feel.

 

In addition, an increase in damping and traction brings decisively better bike control, plus much lighter tires can be ridden. Even in tough conditions "burping”, the dreaded loss of air at low pressure in conventional tubeless systems is eliminated.

Provided tubeless compatible rims - Universally applicable


"Every performance-oriented mountain biker who has ever ridden the system will not want to do without it. The improvements in riding characteristics are similar to major introductions like the suspension fork or adjustable seat post,“ says Hachmeyer. For this it is even worth the additional weight of 200 grams per wheel. As for real hardcore mountain bikers, they now have the additional advantage that they can ride with significantly lighter tires. Because the risk of punctures is greatly reduced, they no longer need heavy downhill tyres.

 


The Procore system is universally applicable. The rim must be tubeless compatible and have a width of at least 23 mm. With narrower rims the assembly is very difficult. The tyre must also be tubeless compatible and should be at least 57 mm wide.

 

The new, patented dual valve is exceptional: It allows you to fill both chambers. The upper part of the valve is a selector. Completely screwed in, the inner chamber is inflated. Completely screwed out - about six turns - the outer chamber is filled.

Joint Development with Syntace


The reason for considering the development of a dual-chamber system was the trend to very wide rims, for example from Syntace. Thus, the riding characteristics of tires with low inflation pressures have become significantly better. Hachmeyer: "This had prompted us to give a great deal of thought as to how we can eliminate the risk of snake bites. In discussion with Syntace we realised that they were already working on the same idea. We are very pleased that we could agree to develop the system together and bring it to market! "

 

The complete Procore Set (two Procore inner tires, two Procore tubes, two AirGuides, tubeless rim tape, tire levers, Easy-Fit Assembly Fluid, two bottles of Doc Blue) is available from specialist bicycle stores and costs 195 euros. In addition, components such as the Procore inner tire (59,90 €), the Procore special tube (19,90 €) and the AirGuide (2,90 €) can also be purchased individually.

if this really works. how long till ghetto versions emerge?

leaboy, May 26 2015 11:56

directly converts +- R2500 based on current exchange rate.

wonder what the lifespan of the system is...

how do you get your Stan's inside? 

Captain Fastbastard Mayhem, May 26 2015 12:30

Same way you do now. Either pour in the tire just before you lever the last bit of bead onto the rim, or use the valve and unscrew the valve stem so that the selector is on the "external chamber" position. 

Martin PJ, May 26 2015 01:01

I am thinking to drill another valve hole in the 29er rim, put 700c road bike tire and tube on 29er. Then put standard tubeless with sealant on top of that on the 29er rim. The MTB tire you pump up first, then the road tube and tire.

Odinson, May 26 2015 01:06

Will you be able to run other tyres brands with this system? 

 

Edit: Never mind. Read the article properly. 

RocknRolla, May 26 2015 01:07

"major introductions like the suspension fork or adjustable seat post"

 

way too advanced for my bike.

 

and too expensive.

Odinson, May 26 2015 01:15

What of tyres with "floppy" sidewalls, where the tyre folds in on itself when running low pressures? Does the inner chamber negate that? 

 

What will this system weigh?

Another small invention to take away unnecessary stress on the trails. Sahmarai swords, swat concept .... great inventions, id buy it

Saag, May 26 2015 01:18

Looks great....will it perform as advertised? Will have to wait and see!

A bit expensive to "try it".

 

What happens if you get a nail or lekker long thorn in there, guess it means another bundle of cash gone then?

I'm pretty sure that procore is not being marketed as a puncture proof solution, in which case your question is rather moot, yes?

 

But to answer your question: you deal with the lekker long thorny issue the same way you would any other puncture. Remember, you can inflate the outer tyre independently of the inner tyre (procore unit). So fix puncture, reinflate, happy days.

Sounds a bit like the Tubliss system for dirt bikes.

Seems like there is plenty info on ghetto options out there...

For me, I'm not sure if the Schwalbe system is worth the cash and I don't think the DIY option is worth the effort.

says 400g additional weight. That is a lot of extra weight to lug up hills.

It is almost identical to the Nue Tech Tubliss system without the rim-lock.

Sorry, as a roadie trying to understand this. At what stage does the extra drag of the low pressure tyre counteract the extra grip?

 

I have a MTB that I play around on with 1.4bar tubeless and have never caught myself wishing for extra grip, maybe extra skill but not grip.

 

Will people actually ride around with tyres at .6 etc?

TheJ, May 26 2015 02:06

I might be missing the points of this. I've been riding tubeless for about 10 years now, if not mistaken. I can probably count on my two hands the amount of punctures I've had during that time, that the sealant couldn't sort out. I use non-UST tyres as well, that have less protection and still only so many flats. I think out of those 10 flats max, only about 3-4 wouldn't seal and required a tube. And as a semi-weight weenie, 200g per wheel isn't for me.

I think it is for people running low pressures and really pushing corners hard (so more aimed at the DH & enduro crowd, I think). The Procore system eliminates (or reduces) the chances of the tyre burping or running off the rim.

what super-mil said. I dont think 0.6 was intended to convey the sentiment that that's a ridable pressure. they are just saying that your tyre shouldnt blow off even at that low pressure. Under hard cornering, a low pressure tyre can rip right off the rim, UST or not. Worse still, sometimes under low pressures, you can hit the rim and literally explode the wheel. Procore gives you the margin to go flat, but roll home bike and body intact.

It sounds like most people commenting here are kind of missing the point of Procore...

 

It's primarily designed to enable you to do two things at the same time:

 

  • Run low pressure for extra grip (Pure Savage, as a roadie you probably haven't been doing the kind of riding where there the "is there ever enough grip?" question arises).
  • Not pinch flat or burp constantly because of the previous point.

 

That's it, simple as that.

Martin PJ, May 26 2015 02:23

At race like Sani2C you can use this, average speeds are pretty high so when you hit a rock or something you definitely bottom out, even at 1.8 / 2 bar. I would like to run 1.4 bar at races and not bottom out on rocks. I would ride 1 bar if I could.

Cool, that makes sense. Just trying to understand the need. :D

 

I'll have you know I have been to the garden route trail park! :P (Didn't stay on the bike much that day though!)

I have heard the minimum internal run width to run procore is 25mm.
True or false??
