Slime Smart Tube 29" X 1.85-2.20 Self Healing Bike Inner Tubes - Presta Valve (Pair)

Ordered these to replace a pair that are 5 years oldI will always swear by these given i have covered a total distance of 6700 miles with them equipped on my MTX 8.6 which has the daily task of carrying shopping and towing a trailer for what they cost compared to the protection they offer is unrivalled especially paired with continental ebike tyres with puncture protection belt the time saved from patch repairs or downtime from punctures cannot be beatenBig kudos to the seller they arrived 3 days before estimated arrival dateWhether you are a weekend rider or daily commuter make sure you have these tubes equipped to avoid downtime from flat tyresFor every bike i buy these are bought alongside top stuff

The goods are great. Arrived ahead of time fitted one tube easy when to fix second but would not inflate as value bent returned both tubes and ordered new the replacement arrived the next day wonderful. Thanks.

Good for commuting where you need to avoid flats.But adds lots of weight to bike

The inners tubes have saved several stops to repair flat tyres while out biking in the countryside. Once hedge cutting season starts so do the punctures. These inner tubes work well and seem to be protecting me from thorns from hedge row cuttings.

I am a long term slime user and can assure you it works. I have changed a tyre only to find I have had multiple punctures (mainly from thorns) that have been healed with slime.After 3 years it seems to lose its effectiveness so I have just bought two new Slime filled tubes. (A lot of tubes seem to have non removable valves otherwise I would have lost bought it by the bottle)

I've used these for 2 years and only had one puncture and that was when I was changing the tire. I cycled through a load of thorns and got a huge one stuck in my tire, I pulled it out and immediately the slime got to work. I not only made it home but 2 weeks later the tire is still inflated.

Got these so wouldn’t have to change tyre as often in event of puncture. 2 months in and had 3 punctures and this on the inside of the rim which is very strange. But they obviously don’t work as slime didn’t seal just wet green gue. Don’t waste your money because patches won’t fit over tube as slime displaces as I’ve also found out.

Sorry, did I mention these are heavy? Yes. They are very heavy.So if you have spent good money on weight reductions on a road or mountain bike, theres little point in purchasing these. I use an MTB in winter months which was inexpensive and not the lightest. Since adding just one of these inner tubes the weight has noticeably increased to the point where hauling it up onto a bike rack at the train station becomes a workout.My experience with them has been interesting. I had a puncture and removed the offending thorn. Replaced with this inner tube and immediately suffered what seemed to be another puncture. Not impressed I pumped the tyre up again. It lost a bit of pressure over a few days but not completely flat. After pumping it up again it has maintained pressure well. So I dont know exactly what is going on, I havent been bothered to investigate. As long as pressure is maintained Im happy and assume the "slime" is doing its thing and as such I would recommend.But they are heavy.......
