Continental Bicycle Tubes Race 28 700x20-25 S42 Presta Valve 42mm Bike Tube - Value Bundle 5-in-1 Bicycle Tube 700c

My husband and I ride bikes to work. You can’t avoid punctures when riding in the city. This pack is very good value for money. It arrived very after ordering (despite coming from overseas). We have already used one tube as a replacement, so it became very handy. Highly recommend.

The tires arrived today and the package contained the tire levers...I had read on here that they did not...Great buy for the price!

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.

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.

Good tubes, arrived quickly.
