Continental Bicycle Tubes Race 28 700x20-25 S42 Presta Valve 42mm Bike Tube Super Value Bundle (Pack of 5 Conti Tubes & 2 Conti tire Lever)

Continental tubes are excellent quality. I see negative reviews but a tube is a tube. I have been cycling on the road for years and have never had a problem with one. The biggest problem is not with the tube but with fine radial tire wire that is common on streets. It arrives via blown tires or sever wear of car tires. The solution! Install tire liners of your choice I have them in my Trek Madone and now rarely have a flat, I just changed tires and two strands of wire were sticking out of the tire side of the liner! Without the liner it would have been two flats, also many tire brands have flat resistant tires some are called “plus” tires they work! Remember when you have a flat carefully inspect the tire for debris before the new tube install when I read you got a second flat you left debris in the tire don’t blame the tube for that.

I am an avid cyclist, mostly road cycling which means that every so often you get a flat and as long as I'm prepared I should have a spare inner tube in my cycling jersey backpocket. I have used pretty much every type of inner tube, both in material and brands. This continental brand inner tube are excellent, they last a really long time and also include tire levers to be able to change the inner tube or even remove your bike tire when the time comes to replace those as well. The reason why I like this particular pack is that it includes enough inner tubes so you don't buy too many, unless you have a ton of storage, which I don't. Secondly, I think you are getting excellent value from this product because of the price and quality. I would highly recommend this product to anyone looking for reliable and durable inner tubes.

My last four inner tubes were replaced because the valve failed. The knurled nut came off or the inside seat started to fail or the inner valve assy started to unscrew and couldn't be re-installed. The tubes were low quality. These are a little more but great quality.

Great tubes! Marked four stars only because it’s easy to accidentally finger loosen the valve core. When filling the tube, a small top screw needs to be partially opened before placing the Presta adapted pump twice now I found the tube lost air overnight as somehow? In loosening the Top screw on the press valve. I also loosened the presta valve core. As this core was loose, it leaked air overnight.Probably a good idea to tighten the valve core into the valve apparatus to prevent this from happening. That’s what I’m doing now. High quality tubes.

May cost a little more, but lasts wayyyyy longer than the competition. Durability and toughness is important, especially when your safety is dependent upon a 1" piece of rubber.

Good reliable tubes. No complaints here.

When I first started road biking I did not enjoy it. Every ride was a struggle. I would slice through tires and grind throughrims like it was no ones buissness. I almost got out of the hobby. Then one day after slicing through the second tire of the day trying to go up a steep hill a fellow rider recommended inter tubes. This product is life changing. No longer does my rim cut through my tire or get sanded away from the concrete road. Travel up hill with an aired inter tube provides slip free use of your tire and rim. It's almost like they never touch because of the cushion of air it provides. Since I started using these thing my tires last far longer. One might say over 1500 miles in comparison to the old 10 to 15. I will not go back to tubeless. Only bad thing is you need air to use them properly. Didn't need that with tubeless.

The tires say "Continental" and "made in China". The tire levers are NOT Continental and one of them snapped off before I even finished installing all the tubes! See the photo for details! The retaining nuts have a bevel so i can use these on presta or schraeder rims without a grommet so i think these are genuine continental tubes but the tire levers are definitely not! The price increased 40% in the last 4 months and these are no longer a good deal! I am subtracting 2 stars for false advertising and sending me low quality substitute tire levers ...
