Muc-Off 20216 No Puncture Hassle Inner Tube Sealant, 300 Millilitres - Advanced Bicycle Tyre Sealant For Repairing Inner Tube Punctures Of Up To 4mm

Product Information

Things can sometimes get messy. If you are ever in a situation where you need to repair the tire tube or the tire tread, you will likely end up getting your hands pretty dirty with all the sealant. Minimal upfront cost. Both Slime and Muc Off make excellent quality sealants, and a small bottle is comparable to the price of a new inner tube.

Even though I test loads of tubeless tyres, sealants and wheels on my own road bikes, I haven't bothered to make the change myself purely because I get very few punctures – maybe a couple every 10,000 miles – mainly down to the fact that I'm not bothered about running lower pressures for comfort. If you aren't too fussed about converting to tubeless but want a bit of added puncture protection then Muc-Off's Inner Tube Sealant will be of interest. However, if you are using Presta valves then that will be your first hurdle when it comes to installing it, as the bottle and kit are designed primarily for Schrader (car type) valves. Run your tires at higher pressure. Since sealants are not meant to deal with snake bites, you should pay special attention to running your tires at sufficiently high pressures. Low pressure increases your chances of getting pinch flats and punctures outside the tread area of the tire. Don’t take chances. Just because you have puncture resistant tires and sealant in your inner tubes it doesn’t mean that you will get no flats. If you see thorns or sharp objects you should still avoid running over them.The water-soluble nature of the Inner Tube sealant requires more to be added to the tube than you would Muc-Off's tubeless sealant – about 90ml for a 700C tyre rather than 40ish, which obviously adds a bit of weight. As long as you have inner tubes with removable valve cores you can fill them up with this Muc-Off stuff.

Muc-Off has used some of the technology from its tubeless range to create the No Puncture Hassle Inner Tube Sealant, a sealant – as you can no doubt work out – for use solely with inner tubes. It doesn't seem to dry out and does a good job of fixing small holes, but the installation tube is too big for Presta valves. Making a bigger hole saw the sealant take a little longer to plug the gap but it achieved it, although the pressure dropped from 90psi down to 50psi. That's still high enough to let you get home without stopping and give it a top up at home or fix/replace the tube. There is a workaround though. That little nut that you screw over the valve right up to the rim... well, if you unscrew that towards the bottom of the valve, you can butt the tube up against that and you will spill very little. Not ideal, but it's doable.Although you can use tubeless sealant in your inner tube, tube specific sealants are designed for your tube and they are going to last longer and do a better job at sealing punctures on your tubes. The best sealants made specifically for inner tubes are made by Slime and Muc Off. Some factors, such as how often you ride your bike and where you store it and how many punctures it needs to fix may come into play in determining the lifetime of the sealant.
