Good spot! Cheaper than fleabay....Decathlon has some cheap double packs but limited sizes

Been this offer for a while. Their tubes have been £2.50 each on their website for at least the last 3 weeks but remember their own tubes don't come with a dust cap or retainer nut (if you need them). They also have some Continental ones on their site (that do include dust caps and retainer nut)..... down from £6.99 to £2.99.

I bought a couple of 700x25 tubes and they had the retainer/dust caps. Not sure about MTB tubes but I'd assume they did too. I tend to use the old retainer/dustcap anyway when swapping out. I do prefer the Conties though

I had a puncture today and had a spare continental tube in drawer so stuck it on:)

Has anyone stuck one of these up their bottom? Just asking.

Decided to go tubeless so easy to do and hopefully no more punctures ever.. I got a box full of inners I hope will never be required, although good to carry a spare

Don't buy if you are doing any trail riding, they don't hold well. blown 3 tubes in two days at Llandegla

These are fine for £2 a pop - no pun intended - as I really have never seen the different between these and tubes that cost 5 or 6 times the price. The tyre is the important first line of defence - if something gets through the tyre it is pretty likely to tear or puncture any tube. Look at the expensive slime tubes - you will find loads of people slagging them off whilst others think they are fab.

You can buy an expensive inner tube, take the bike out for a ride and get a puncture within a few minutes. Pot luck.

Great deal, thanks for the heads up OP!
