lane March 22, 2010 10:05 AM ive used these for 2 years with no flats, regular tubes on the other hand... foghorn March 22, 2010 10:47 AM The word on the street is that the slime doesn\'t work. What does work is Stan\'s No Tubes sealant. With tubes or tubeless, Stans will seal a surprisingly large cut in a tire or tube. I have even had good success with a concoction of my own before Stan\'s became available. fenriq March 22, 2010 11:51 AM I\'ve used Slime in my mountain bike tires for more than 10 years now and love the stuff. I never flat out because the Slime is always there to seal the little punctures. This stuff is awesome and I\'m outfitting my wife\'s bike with these Slime tubes right now. Yes, the stuff does make the tube and wheel and rotating mass heavier but its worth it virtually never having to stop to change or patch a blown tube. bas March 22, 2010 02:59 PM The idea seems viable, but... I cycled a fair amount of trips carrying baggage through Europe. I rarely had flat tyres, even some trips in excess of 2000 km went without a single flat. That was using kevlar reinforced tyres and regular (brand) tubes. The idea is that you should keep the tyre pressure at maximum so the tyre is hard enough to break or bend whatever causes punctures. And.. you will really be surprised at the reduction of roll resistance with hard tyres. Especially the mountainbike variety. silverneedle March 22, 2010 03:34 PM Just get the armoured tyres which work very well, they do the same job without all the extra potentialy environmentaly damaging rubber goo. Plus a puncture only takes ten minuits to fix once youve done it a few times you wont be afraid of getting one any more. Facebook User March 22, 2010 06:57 PM Got kids? Got neighbors that won\'t keep their puncture weeds (AKA goat heads) killed off? Put some Slime in their tubes or get the pre filled Slime tubes and you won\'t be wasting time and money fixing and replacing the kid\'s bike tubes.\'Course the best fix is to get the kids to not ride through the weeds. Glenn Ryan March 23, 2010 08:27 AM Use slime on my pushbike for approx 10yrs, the only time I have fixed a puncture since using slime I rode 10Kms home on a mostly deflated tyre[still got me home]when I pulled out the tube it had 7 holes in it one with the broken stick still in the tube [approx8-10mm thick]so whacked some patches all round shaking my head over the number of sealed punctures and rode to work in the morning.Brilliant stuff highly recommended. Gadgeteer March 27, 2010 09:44 AM Slime tubes have been around for years. I know plenty of people who hate them, saying they don\'t work. Another good alternative is True Goo, which claims to work much better and faster than Slime. Quite a few good reviews of that. As for greenness and safety, ccording to its website:\"True Goo Tire Sealant is non-toxic, non-flammable, non-reactive, non-irritating and environmentally friendly. When spilled, True Goo can be wiped up and True Goo is safe to be rinsed to a drain. True Goo should not be ingested.\" Will, the tink September 10, 2010 04:30 PM True Goo should not be ingested? Well, I don\'t want it then! It\'s not totally totally GREEN! Don\'t you just love the \"green\" movement? In everything, moderation is the key! MQ May 13, 2012 03:44 AM Has nobody sort of noticed that All of these Goo slime or other 'latexy' antileak compounds are coloured Green, is there a message.... Don't trust anything that has to be coloured green (especially fluoro-green to be Environmentally friendly....Now they just need non toxic leak proof anti *[viral;retro-viral;bacteria;little squiggly thing] prophylactics... BTW ,I have used stuff like this for over 15 years.. Not a Puncture to repair.. the tires only leak slowly if the bike isn't ridden for a few months, regular riding keeps it all firmed up... (Every brand had Proponents and opponents) AND it works in road bikes as well...If anyone has ridden in England during hedge trimming season ,they will know the value of 'slime'. Hawthorn Kills tyres.
