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

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.

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.

As other reviewers state, doesn't come with the tire levers in the picture. But you already have a Crank Brothers or some Pedro's levers anyways right? Five tubes came, seem to be of good quality and unbeatable price. I installed two and put one in a ziploc as the ride along spare. I should be good on tubes for the road for a long time. First ride went great with no issues whatsoever. I will try to update the review in a few months or a year.

I felt this product does worth every bucks I put into since it feel that it’s well made and it maintain pressure very well. Air capacity stays instead leaking. It is thick and fit well to my tires. Top performance.

Product and delivery as specified. Only re-air ~ every 2 months. Good quality and value.

I ride a lot. I have no flat tires and typically get 2 or 3 flats a year. I add metered air via compresser at 10 psi below recommended max. I bought a batch of 5 of these tubes ñast year at this time, and got arouund to using these over the last 3 weeks. I got a flat, replaced it with a spare tube ( both from this batch) and got a secomd flat before I made it home. Walked it home, replaced it with a third tube and added a fourth in my spare pack. Same thing happened again next ride. Just got back from my third ride where the SAME thing happened a third time. I patched one of these and it blew on yet another seam) I imspected my rims and tires without issues. I inspected the tubes and they consistently blew or leaked at seams. I have used Continental tubes and Gatorskins for decades. Supposedly this company is different in their tube assembly q/a process in that they fill to inspect for such defects. That did not happen here. I will try Schwalbe, and I will skip Amazon and try my LBS. Defective pqrts arent worth a few bucks considering the major adverse impact they have on my limited training time.

I have not yet had need for a replacement tube (🤞) but I have had confidence in the Continental brand. These are made in China. I did inflate one as a test. Looked fine. Didn't spot any flaws or weak spots. I can post again when I have used one.

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!

Good tubes, arrived quickly.

I have purchased these particular tire tubes a couple of times over the years without any problems. I purchased this pack because I like to have extras on hand. I think whoever monitors the listing may want to replace the existing photo. To me, it’s a little deceptive! It infers you are getting a pair of tire levers included with the bundle. This is NOT the case. You get the bundle of 5 boxed tubes only, so as always, read the listing description thoroughly.

I had high expectations for these tubes, given the price and my 100% good experiences with Continental tires over the years, but these inner tubes are garbage. The valve closure snapped off WHILE I was on this tube's first ride, and when I went to pump up the tires for another ride, the closure jumped off and the air blasted out as soon as I took the cap off.
