Continental Race 28 700 x 20-25c Bike Inner Tubes - Presta 80mm Long Valve by Continental

The tubes are excellent - I've had fewer punctures on my road bike with these than I think any other brand I've tried. However do check that the exact size and value length you are shipped matches what you ordered. For this order I got the right tyre circumference shipped by the wrong valve length - which is important for your road/TT bike naturally.

Having run through my most recent 5 pack I'm starting to agree with other reviews here questioning the legtimacy of these being Continentals (if Contintentals are meant to be as good as people say). To be clear I haven't used any other brand since taking up cycling.The last 2 on my front and back tyres are losing air too quickly, I use scwalbe endurance tyres so I am doubtful it's a puncture (I can't hear or see anything from the tyes). I had one valve break off completely after using a hand-held pump on it, maybe I was too rough. In the pack there was some variation on valve length from box to box which I am sure in and of itself isn't suspect but I don't know I am just iffy about buying these again. Decided on a different brand and seller this time.

These inner tubes are truly awful. They cannot seem to cope with any decent air pressure. My normal bike pump, which usually works fine cannot seem to get it up to a decent pressure. After trying a better pump the pressure very quickly fell out of the tyre and I had to pump the tyre up before every journey (3-4 times a day)

I had two blowouts on a brand new bike and quickly used these tubes in my new wheels. So far so good. I have had no issues at all, and I've ridden close to 200 miles.They handled the hot weather fine, and I've had some hard impacts on pot holes which they've survived too. I'm running these in 25mm tyres at 95psi. They come fairly compact, which is good as I can fit 1 spare into my saddle bag.

I bought this for my brother who is big into cycling and we open the first box and there was a massive hole in the tire so I was very disappointed about this I will look for a different supplier to buy this next time
