Slime 30058SL Bike Inner Tube with Slime Puncture Sealant

I've been using these for years and in conjunction with a good quality puncture resistant tyre I haven't had a problem puncture for that long either. Just bought a new Giant bike so got one of these for the rear. The idea behind these tubes isnt that they will stop ANY puncture but basically small ones. thorns, bits of glass etc, if you get a massive gash it wont help, also I'm not sure how they fare on 'pinch' punctures. Ive been use to mountain bikes and trail bikes my new one is a road bike so hopefully they'll serve me as well as they have over the last 5 years or so. The only thing I would draw your attention to is that the presta valve on this tube is very long, its a lot longer than the one I got with the bike I bought, there is a good 5 cm or so protruding above the tyre rim, this doesn't cause any problem and is obviously for use with bikes that have extended internal rims. as I say my advice is to use these with a good kevlar puncture resistant tyre, It's a combination that has saved me many a time

manufactured with massive holes in them for your frustration replaced a tube today on the side of the road it poluted the tyre insides with green slime because it had a missive hole in it So I caught a taxi home and used another slime tube Same again - I'm flabbergasted that such wretched quality is so demonstrably manifest with these tubes. Than good ness they dont make brake pads - I'd probably be dead

Very heavy tube must weigh more than the tyre !!

Ride 22 miles a day to work and back, part road mostly cycle paths and pavements designated as cycle paths. I was getting flats almost weekly, 3 Fridays in a row on the way home in one streak :O Had these tubes in for about a month and a half now and no flats :D I have pulled out various objects inc thorns and glass spotted due to small amount of Slime on tyre but tyre has never lost noticeable pressure. Read about weight and balance but can honestly say I have not noticed any difference in my ride, apart from lack of flats, so would highly recommend you try these if plagued by flats :D FYI, Tyres I'm running are RoadSport Reflect

I have tried tubeless tyres for a year. But had a few punctures on the rear wheel. The front has been fine. So knowing I had a couple of 100 mile rides coming up I replaced the rear tyre on my bike and added this inner tube. All went well with the rides. But I was also happy in the knowledge that if I did have a puncture it would be a lot less faff than with a tubeless tyre.

I used few times and have noticed that only very small punctures are "fixed". punctures which are more than 2 mm seem to be an issue as the sealant can't do anything about it.

Replaced my inner tube on the 11th August 2025 and then sat in a pub on the 25th August with the bike rested against the bench next to me and the inner tube just popped. Green slime everywhere. While I may attempt another purchase to see if this was a one off incident my first experience was not good. The green slime was very messy and got everywhere which would of been a nightmare if it had happened elsewhere where I didn't have the facilities to clean the tyre up before replacing

I have used slime tubes for over 4 years now, mainly on mountain bike amd off road tyres. The benefit of self sealing when miles from anywhere is a god send, usually a few pumps of extra air to replace the lost from the puncture before it seals is enough to get you out of trouble. I decided I would try them on my gravel bike just to give some extra peace of mind when touring in France. They have performed perfectly- for this price it’s worth it!!

I've used slimes for decades, so I don't know what has happened to their formula, or maybe I just happened to get four duds in a row (one puncture was from the rim, so I'm not counting #5--my bad) from gigantic goatheads, but these tubes are not working as they used to. I've commuted on goathead clustered highways, and yes, I'd get slow leaks, but these recent four didn't even leak the Slime. They just flatted and wouldn't pump back up. My advice to Slime? Go back to the old formula. Please. Or don't sell out-dated tubes. Please. Thank you.

Prodotto di qualità, rispetto alla camera d'aria che ho sostituito e molto più robusta sia per la gomma che per la valvola, unica pecca la consegna in quanto il pacco era distrutto e tenuto insieme con una palla di scotch, ma il contenuto era a posto

Fast delivery

Lovely Tube 👌

Estou a usar e gosto do produto!
