## Description

5 Continental Bike Tubes - Race 28 - Width 20-25c with 42mm Presta Valves - New in Original Conti Retail Packaging - These are not Bulk Tubes

Review: Good tubes - The tubes delivered are exactly what is described within its product description. From my experience, the tubes are very well made and handle very well. Replacing/installing tubes takes no more than 15 minutes and the tubes never become and issue for me. Each individual tube has lasted me anywhere from 6-15 months, and I still have year-old unused tubes due to how long they last. The only minor caveat is that as the tube ages, it does lose pressure each ride. You’ll probably have to start re-pumping your tires often if you use your bike very heavily. Overall, I am quite satisfied with my purchase, more often than not, I am fixing other parts of my bike rather than replacing a popped tube.
Review: Nice design of valve stem base. - Zero issues with the installation. The valve stem base has a slight flare to let it settle into the drilled hole in the wheel. My wheels came with Schrader tubes originally, leaving a tiny bit of play around a Presta tube valve stem base. These Conti's occupy that miniature space nicely.

## Questions & Answers

**Q: Are the cores on these tubes removable?**
A: The valve core of the valve stem is removable.

**Q: Are they genuine?**
A: If they come in their own individual box and from Amazon, then my experience has been that they are genuine. If they come from another seller and packaged 5 in a bag, then I have had horrible results and had to return them.

**Q: Is this product for wheel size 28 or 29 inches? connfusing description says 29, box says 28.**
A: 28in, 29in, and also 700c are the same diameter rim, they just refer to different tire widths.
27in is a different size wheel though, so look out for that.

**Q: Have any of you tried the 20/25 in a 28 tire?**
A: Hi, I hope this finds you super well. We wouldn't recommend trying. Continental makes the same tube designated "wide" which is meant for 25-32 width tires. Happy riding!

Zero issues with the installation. The valve stem base has a slight flare to let it settle into the drilled hole in the wheel. My wheels came with Schrader tubes originally, leaving a tiny bit of play around a Presta tube valve stem base. These Conti's occupy that miniature space nicely.

### ⭐⭐⭐⭐⭐ Great inner tubes for value and durability
*by D***N on August 31, 2023*

I ride a Cannondale SR900 with Ksyrium wheelset and use these tubes with my GP5000 tires. The durability on the tubes is great. I typically ride on a road with some debris on it and well maintained trails that still has more than a few bumps. The tubes have held up great and consistently hold pressure well. I am very pleased with the purchase and it is nice to buy the tubes in bulk to save a little bit of money. Great product and would buy it again when I need to.
