Rated 5 out of 5 by Produto de alta qualidade. Produto muito bom, é a quarta vez que ele me socorre.Ele fez o remendo sozinho não precisou de parar a bike para estar remendando o pneu, muito bom mesmo. 06 September 2014
Rated 5 out of 5 by No punctures since Had in my tubes for 6 months over the winter, and no punctures which is a vast improvement. Supplied tube is too big to fit properly over skinny Presta valves bodies (you have to unscrew the valve itself), but luckily I had some spare soft tube of an intermediate size to fit in between. 06 April 2014
Rated 5 out of 5 by Convert or top up self sealing tubes This is ideal if you want to convert your current tubes or top up your existing self sealing tubes. 16 March 2014
Rated 5 out of 5 by Does the job! Fed up with punctures? Simply add this to your tyres. Comes with valve remover and easy to complete. Have used this in all my bikes inc my little ones pushchair/pram! 22 January 2014
Rated 5 out of 5 by Герметик Хороший герметик. Удобная форма и тртубочка подачи.Позволяет сохранить чистоту ваших рук и пола. По сравнению со "Стеновским" чуть гуще - может даже получше заделывает проколы с меньшей потерей герметика, но проверить сложно. 16 December 2013
Rated 5 out of 5 by june 2011, now nov 2012 SLUDGE JUST KEEPS WORKING. I've had this sludge in my innertubes for18 mounths now, and had lots of punctures, but NOT ONCE HAVE I HAD TO STOP AND MEND ONE.I just pull out that thorn and ride on....and on....aand on...you get the message? Some say it makes the wheel slightly heavier, but if you just feel the weight of the bottle when you get it,you will say it's not worth worrying about. I have noticed that when you get lots of punctures on the same ride you may loose a little more air than you would like, and a couple of pumps will get the pressure back up. But on one canal path ride (after the hedge cutter had been) i got 15 hawthorns out when back home, and my tire was still 40psi. was 50psi when i started. I rest my case!. 23 November 2012
Rated 5 out of 5 by It keeps you going. It does exactly what it says on the tin!. I've never needed to repair a tyre in all the months i"ve used this. Many times i"ve pulled thorns out and hiss!!!, then revolve the wheel and emediatly it stops. When riding you done even know anything has hapened. On one ride i came home with 5 thorns in the tyre, and still i've not had to put a repair patch on anywhere. In contrast, on holls, i hired a bike to ride Exmoor and got a flat on the way down, If sealant were in the tyres, i;m sure my ride would have been trouble free. 15 August 2012
Rated 5 out of 5 by makes the wheels abit heavy but overall you get used to it and closes all the punctures! i had the same tubes in for about 2 months (still do),GREAT PRODUCT!! 03 August 2012

Answer: 
This sealant kit is compatible with any valve which has a removable valve core. This should be easy to discover as the top section of the Presta valve will thread out if it is compatible.

Answer: 
You have to remove the valve by unscrewing it, but yes the sludge will go in. The tube attached to the bottle is sized to fit bigger valves though, so won't fit properly on the Presta valve body and the sludge will leak out the side. Its not too difficult to clamp it with a jubilee clip though if you've got one spare.

Answer: 
Many Presta valves have removable cores which can be identified by a flat section at the top collar; below this is the thread which holds it in place.

Answer: 
For a standard 2.0” mountain bike tire, we recommend 2 ounces of sealant (around 55ml). You may want to use 3 or more ounces (85ml) in larger mountain bike tires or for the initial setup in tires that you find difficult to seal. For road and cyclocross tires we also recommend 2 ounces. One 250ml bottle of this should be plenty for 2 wheels and leave enough for a top-up in the future.
