Continental Race 28" 700 x 20-25c Inner Tubes - 42mm Presta Valve Road Bike Tube

Using these for years. Great price

Bought this as a spare for my road bike. It's fairly cheap and easy to install. The valves could get worn but I think it's after several years. It's probably a few dollars cheaper buying it online versus at the store

They seem to be genuine tubes. A bit long of a valve for my rims but they work. One popped during installation because I bit it with the tire lever, but that's my fault. They haven't broken in proper use.

Training tires that will last you for thousands of miles, feel very grippy in the corners but roll super smooth and will not pick up punctures easily. I don't race anymore and when I did I used tubular rims not clinchers; but, these tires along with my Campy Eurus rims would be up to the task.

great tires

These inner tubes have been dependable and easy to install on my road bike. The 42mm Presta valve is the perfect length for my wheels, and the tubes hold air well between rides. They're lightweight, well-made, and exactly what I want to carry as replacements for training and longer rides.

I had two of these tubes with me on a ride as spares. I got a flat and fitted the first, and the valve stem unscrewed when I tried to take the pump off after inflating it. After several tries at trying to pump the tire, then remove the pump without the valve separating into pieces, I gave up and tried the second one. Almost the same thing happened, but I was luckily able to grab the loose part of the valve and screw it back in before it let all the air out. If I hadn't got lucky, I would have been stranded miles from home.I have been cycling for 40 years and have never even heard about valve stems disassembling themselves like this. I was happy to pay a little extra for a trustworthy brand, but wow, I was very mistaken about Continental. I have used many brands of inner tubes over the years, and I've never seen such low quality.If you only ever use bike pumps that push on and then grip the valve, you may be okay. If, like me, you take a mini pump on rides that screws onto the valve, do not waste you time and money on Continental tubes. You may find, like I did, that the inner part of the valve unscrews when you try to remove the pump. It's just not worth the risk when there are so many higher quality alternatives.

Valve stem seems weak and bends easily
