Continental Presta Valve Black 25 32Cc Review

I bought four of these inner tubes for my bike, they are exactly the size I need and each one is cracked or defective. The first had a small hole right in the liner where the rubber fuses were, the second had a leaking valve stem, the third burst when I tried to install it, the fourth popped out about a week after I finally got it working would have. . Don't buy these cameras, you're only spending $45 for a week's riding.

I ride a bike with wider training tires, typically 25-35 miles per ride. Having an apartment on every trip is frustrating, but road hazards are usually the culprits. Changing a tire on the road can be dangerous. For this reason I use vinyl liners to minimize flat surfaces of nails, spikes, etc. However, the last three of these tubes came loose at the seam. All within +/- 10 miles. The description says there is no seam. However, there is a seam and 3 not along the seam.

My bike has 27" x 1-1/8" tires and inner tubes need to be replaced. It's an old bike with outdated tires (but still runs) and I wanted a nice set of inner tubes that would fit the right tires in the future. My first choice was Schrader valves, but Continental offered a good future replacement tire with matching tubes with Presta valves. I was having trouble converting from English to Metric units and ended up with a 700 x 28c tube. My theory is that the tube has to match the tire so Continental

Not that I didn't like it, it was defective. The cause of the inexplicable loss of air could not be found. Place the fully inflated tube underwater without showing where the air will exit. Reassembled and an hour later the tire went off again even without using it. I was delighted when I saw a replacement was on the way until I saw it wasn't a 700x25 so I canceled it otherwise I would have happily received it. So here I am without a new tube replacement and with a defective tube. 06/04/2020…

I closed my bike shop 4 years ago. I've changed thousands of cameras over the past 30 years. The Continental tubes are of very high quality. They are thick enough and the rubber is quality enough to stretch from 700cx 25mm to 700cx 32mm. I worry about other brands as they get pretty darn skinny at 32mm at 105psi. You can pay a little more for the Continental brand, but very little. But the quality is much higher. They last much longer with far fewer problems over the life of the tire. Choose…

Read information about the product! These hoses come with removable valve cores. So if you have a custom wheel that needs longer valves, you can replace the included stem. For everyone else, it's mostly more of a nuance than anything else. If you're pumping up tires with a floor pump with a quick-release head, it might not be that big of a deal, but if you're using a pump that has to be screwed onto the valve (like your regular mini-pumps) then it becomes a problem. a huge PITA because if you…

My review on this product reflects my opinion of these lamps when new. While the review is positive, this review is intended to alert others that you may or may not get a bargain on Revain stock. So far I have bought 4 of these tubes from Revain inventory. The price is EXCELLENT. I paid about two dollars each. I bought two each of "Condition: Used - Like New" and "Condition: Used - Very Good". The latter were described as "Minor blemishes on the corner of the article". The item will be in its…
