Continental Race 28 700 x 20-25c Inner Tubes - Long Presta 80mm Valve (Pack of 2), Black

Always good.

Perfect for their intended use. The valves breathe right length too.

Good qualityGood value for money

fit my purpose

Terrible product. The rubber is too thin and easily punctured. I have had a faulty one that split around the valve without riding anywhere. I have put on lots of inner tubes and these just aren’t worth the risk. The fit ok but Don’t waste your money, you can buy cheaper and stronger inner tubes at half the cost.

Great quality tubes, from a great manufacturer . I have a few of these

for those deep rim wheels these are prefect .

The long stems are useful for deep tyres, and in general these inner tubes are pretty good. Unfortunately, one immediatly punctured, so quality control is not the best.The screw-in valves as well make it very fiddly to pump up with a screw on pump (eg. lezyne pocket drive), should have dabbed on some threadlocker before the ride.
