hoots man Posted September 17, 2009 Report Share Posted September 17, 2009 Puncture proof inner tubeUnited States Patent 6418991Abstract:An improved pneumatic tube formed from a semi-rigid, air-tight rubber core encased by a plurality of thin, armoring Kevlar layers bonded to the exterior wall of the core. The composition can be used as inner tubing for cars, bikes, motorcycles, planes, and any kind of vehicle having a pneumatic inner tube. It can also be formed into a puncture proof rubber raftcan anyone get anything like these? Quote Link to comment Share on other sites More sharing options...
monkeyseemonkeydo Posted September 17, 2009 Report Share Posted September 17, 2009 Sounds heavy. Quote Link to comment Share on other sites More sharing options...
MattPhotos Posted September 17, 2009 Report Share Posted September 17, 2009 Actually, kevlar can be very light, depending on the thickness required to stop a puncture. My concern would be that it probably would not stop pinch flats still, as the kevlar only provides impact resistance as such. I would image it would cost a fortune and inevitably only be available in road bike sized tubes! Quote Link to comment Share on other sites More sharing options...
Skoze Posted September 17, 2009 Report Share Posted September 17, 2009 (edited) Terry!!! Never realised you were on here...Can't say I know where you'd get some from, do you know any more about it? Sounds like it could be pretty expensive, and would it do anything against pinches?EDIT: woah you're quick Edited September 17, 2009 by Skoze Quote Link to comment Share on other sites More sharing options...

Anything made of rubber but which is semi-rigid isn't going to be featherweight... Quote Link to comment Share on other sites More sharing options...
davey_norwich Posted September 17, 2009 Report Share Posted September 17, 2009 my local bike shop sells thorn proof inner tubes, the seem pretty puncture proof too me, unless you ride over a nail Quote Link to comment Share on other sites More sharing options...
Guest itstroy08 Posted September 17, 2009 Report Share Posted September 17, 2009 this is your best bet, http://www.notubes.com/support_movies.phpi really want to try it. Quote Link to comment Share on other sites More sharing options...
shamus Posted September 17, 2009 Report Share Posted September 17, 2009 The thorn proof tubes are heavy.They don't stop snake bites and have the added bonus of ejaculating green slime into your tyre, so fixing it is messy as well as frustratingA semi rigid core would also hamper grip? We run tyres at low pressures is to increase the traction, adding extra stiffness would surely be detrimental to that? Quote Link to comment Share on other sites More sharing options...
N.Wood Posted September 17, 2009 Report Share Posted September 17, 2009 Just buy a Rain King/Der Kaiser and never get punctures and be done with it. Quote Link to comment Share on other sites More sharing options...
Guest itstroy08 Posted September 17, 2009 Report Share Posted September 17, 2009 http://www.notubes.com/support_movies.php also claims to stop pinchflats, wonder if its possible to try on a drilled rim? Quote Link to comment Share on other sites More sharing options...
6ft-midget Posted September 17, 2009 Report Share Posted September 17, 2009 this is your best bet, http://www.notubes.com/support_movies.phpi really want to try it.I was just wondering, all those examples show higher air pressure applications, how well would it fare on pressures of 20 PSI or lower?

forteh Posted September 17, 2009 Report Share Posted September 17, 2009 I was just wondering, all those examples show higher air pressure applications, how well would it fare on pressures of 20 PSI or lower?They 'burp' the air out the sides when the tyre folds off the rim, fatmike ran his front wheel tubeless for a while but it wasnt good enough for the rear Quote Link to comment Share on other sites More sharing options...
hoots man Posted September 17, 2009 Author Report Share Posted September 17, 2009 http://www.notubes.com/support_movies.php also claims to stop pinchflats, wonder if its possible to try on a drilled rim?thats the thing, our drilled rims. low pressures make it harder to make air tight as well but could be possible.Just buy a Rain King/Der Kaiser and never get punctures and be done with it.yet to try conti's tyres. minions ant the moment and have done for ages. reckon conti next though.
