News bot Posted May 26, 2015 Share 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.Click here to view the article Link to comment Share on other sites More sharing options...

Captain Fastbastard Mayhem Posted May 26, 2015 Share 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 Posted May 26, 2015 Share 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. raptor-22 1 Link to comment Share on other sites More sharing options...
Odinson Posted May 26, 2015 Share Will you be able to run other tyres brands with this system? Edit: Never mind. Read the article properly. Link to comment Share on other sites More sharing options...
RocknRolla Posted May 26, 2015 Share "major introductions like the suspension fork or adjustable seat post" way too advanced for my bike. and too expensive. Fisan and IH8MUD 2 Link to comment Share on other sites More sharing options...
Odinson Posted May 26, 2015 Share 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? Link to comment Share on other sites More sharing options...

Saag Posted May 26, 2015 Share 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? Link to comment Share on other sites More sharing options...
Capricorn Posted May 26, 2015 Share 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.

Pure Savage Posted May 26, 2015 Share 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?says 400g additional weight. That is a lot of extra weight to lug up hills. raptor-22 and _David_ 2 Link to comment Share on other sites More sharing options...
