ContinentalRace 28" Wide 700x25-32c Inner Tubes - 42mm Presta Valve (Pack of 4 w/Conti Sticker)

No problem - work with excellence!

These tubes went on my 700x28mm tires-rims well. Look substantial without being heavy. Nice presto valves and stems too!! A sent wrong tubes the first time, but got it right on second try.

Continental Race tubes are a solid choice for cyclists seeking reliable performance on the road. I've been using them for quite some time now, and they've consistently impressed me with their durability and puncture resistance.One thing that stands out about these tubes is their excellent construction quality. The materials used feel robust, yet they don't add unnecessary weight to my ride. This balance between strength and weight is crucial for me, especially during long rides where every gram counts.Another aspect I appreciate is their compatibility with a wide range of tire sizes. Whether I'm riding on narrow road tires or slightly wider ones for added comfort, Continental Race tubes fit snugly and provide a secure seal.In terms of performance, these tubes deliver a smooth and responsive ride. They maintain consistent air pressure, which translates to predictable handling and minimal rolling resistance. Plus, I've experienced fewer flats compared to other tubes I've used in the past, which is always a welcome relief, especially during spirited rides or races.Overall, Continental Race tubes have earned my trust as a dependable choice for road cycling. They strike the right balance between durability, performance, and weight, making them a worthwhile investment for any cyclist looking to enhance their riding experience.

Issa Tube. Good deal for a 4 pack.Ran these on my 32mm wide gatorskins. Ran out of them and this listing was sold out too so I gambled on 700x20-25 continental tubes. They worked too.I also want to clarify that I'm not getting punctures from glass or small road debris. The roads here just suck and pinch flats are way too common with the potholes.

Reliable as they always have been.What more can someone say?

Not great about punctures. I imagine if I didn’t need to use sealant due to the crappy roads where I ride, I would find these tubes better, as they do seem a bit lighter than brandless tubes.

Good tires, I use these all the time. They seem to be durable, and do not leak. They fit the bike tires well. I do recommend and will purchase again. They are a good price for multiple tubes.

I bought these for 2 reasons, 1) removable valve core so I can juice the tubes with sealant and 2) they are thick and durable. Sure they add an extra few ounces to my bike, and shave a few seconds off of my course times, but the time I am saving by not dealing with flats is well worth it. I was sick of patches and cheap tubes that lasted a few hundred miles, on these I have no misgivings about going on 50+ mile rides wish just a patch vs taking a spare tube.
