Reliable and Durable Tubes for Serious Cyclists
I used the Continental Race 28 (700c) tire tubes for a while now, and they have proven to be an excellent choice for both my daily commutes and long-distance rides. Hereโs why I highly recommend them: Durability: These tubes are incredibly durable. Iโve ridden over various terrains, including rough roads and gravel paths, and theyโve held up remarkably well. No Punctures, and the tubes maintain their integrity even after extensive use. Easy Installation: Installation is a breeze with these tubes. They fit perfectly into my 700c tires, and the valve stem length is just right for my rims. The Presta valves are high-quality and donโt leak, ensuring consistent air pressure. Consistent Performance: The tube provide a smooth and reliable ride. They hold air well, and I donโt have to top up the pressure as often as I did with other brands. Lightweight: Despite their durability, these tubes are lightweight, which is essential for maintaining speed and efficiency during rides. They donโt add unnecessary weight to my bike, making them ideal for racing and long-distance cycling. Value for Money: Considering the quality and performance, these tubes are excellent value for money. They last longer than cheaper alternatives, which means fewer replacements and overall savings in the long run. Overall, the Continental Race 28 (700c) tire tubes are a top-notch choice for any serious cyclist. They offer durability, reliability, and performance that you can count on. Whether youโre commuting, training, or racing, these tubes will not let you down. I highly recommend them!

Good value tube for 28mm or larger tyre
Pro: Quality tube. Cons: it does not fit easy on 25mm tyre as it is wide tube.

Good value for money but nozzle can be a problem
I have ordered a few of these and they seem to be of adequate quality but the nozzle can often become faulty and let out air. Quality control isn't great on these but for the money, I think they are good value.

100 miles+, no problems.
Ordered two. Both came individually boxed, as per the photo, in Continental packaging. After reading some of the reviews, I pumped both of the tubes up. Nothing much but enough to see if there was any leaks and / or deformation. Nothing unexpected, just round, black tubes. One valve core unscrewed when I removed the pump which was a bit annoying, but screwed it back in and then tightened it with a valve core tool and no problems since. Probably was only finger tight from the factory. Since ridden over 100 miles with 700x30c tires @80 psi with ~95kg of bike, me and commuting stuff. No problems, no loss of pressure. Off to buy another one of the same as a spare!

Loose Valve
I have used these tubes for years without any problems. However one of the pair I have received this time fitted fine., but when I removed the dust cap to check the pressure the next day the whole valve flew out . I managed to find it and screw it back in tight but if this had happened out on a ride I would have been i trouble. Needless to say I tightened the valve in the other tube. Spoke spanner works for this.
