Continental quality and value.
Size: 700 x 20 - 25mm Set name: 2 Pack
Have used Continental tires and tubes for a few years now switching away from Michelin. Our rides are mostly city urban streets and bike paths and regularly got flats when running Michelin tires and tubes. After switching to Continental tires (Gran Prix 4 Season) and tubes. 🤞🏻🤞🏻🤞🏻no flats. These medium weight tubes and their “supersonic” lightweight tubes perform perfectly. Note these use are in the 70 gram weight range while the supersonic tubes are 50ish grams. Just a bit heavier than those finicky TPU tubes which failed within a month if not right out of the box. These tubes hold air for days if not a week or two. Nice ride and durable. Make sure to order the correct stem length to fit your wheel rims. Toss the valve stem nut never thought they would rattle until I found out it was the reason my front wheel rattled while rolling slow enough to hear it. Go figure ... show more

They work
Size: 700 x 20 - 25mm Set name: 4 Pack
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.

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

Reliable Tubes for Road Riding
Size: 700 x 20 - 25mm Set name: 2 Pack
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. ... show more
