Corki Cycles 700c Bike Tire Inner Tubes 700 x 23c 24c 25c 28c 30c 32c 35c 37c 38c 40c 42c 43c Presta Schrader Valve 48mm 60mm 80mm, Heavy Duty 28 Inch Bicycle Tube for Road Gravel Fixie Hybrid 2 Pack

They fit properly and feel like good quality.The tire tools were an added plus and really helped with the removal and installation.

I just got these and so far I like them a lot. I just bought two more sets before price goes up. I did not had much luck with Continentals as they are pricey yet very fragile. I had difficult time inflating my 700cx23's to 100PSI, they would easily puncture. So I figure give these a try. I will update it in about 400-500 miles.

You can't really get too descriptive with a basic inner tube. But I'll do my best.It arrived quickly...2 days from order to delivery. Basic pack of 2 inner tubes, typical expected thickness, very reasonably priced. Noted that the size is exactly what I specified. Pumped up one, no holes/leaks detected. I was surprised to see that it included 2 steel tire levers...I don't remember that being in the description. Because they're steel I won't be using these with my carbon rims, but always nice to have some available for use with cheaper rims, particularly with tighter tires that break the plastic levers!Certainly worth the money that I paid.(I don't give 5 stars unless something is truly spectacular and blows me away, so 4 stars is still very good!)

The rear rim on my road bike chews through tubes like they're going out of style, and this has become my go-to replacement. I use the 700c x 23mm size with a Presta valve. I've used about 4 of these tubes so far. They all fit as advertised, and I've never had a defect, mis-ship, or anything remotely negative happen. The included levers are an extra bonus. They're so much better than the plastic ones I had from various tire kits, and because they come with every pack of tubes, they're super convenient. Yes, I should probably do something about my wheel that keeps eating inner tubes. Until I do though, these tubes are a fantastic low cost, high value option to get me rolling again quickly.

Ordered my inner tubes and levers and only the tubes arrived. I reached out to customer service in hopes of getting the levers and they responded promptly and kindly, sending me not only the levers but another pair of tubes.

Bought for my single speed bike. Tried the first one, and it leaked from around the stem. Tried the second one and it seemed fine, until about 10 minutes from home even if went flat. Found the hole, and upon inspection, nothing in my wheel orroom tape to cause this. Very disappointed

The size fit perfectly and it came with installation tools.
