corki4-Pack Road Bike Tubes 700 x 23c/25c 28c/32c 35c/43c - Butyl Rubber 700c Bike Tube Replacement - Presta/Schrader - 48mm / 60mm

Really disappointed I bought this 4 pack bike inner tubes thinking they were good quality ...I just used my last one out of the 4 pack ..I got flats realy quick they didn't last much

Consistently, I am jumping off of sidewalks or driving through glass and I can say that so far I have not had any issues with the valve holding in place with all the extra pressure

It was nice getting a set of 4 tubes for a good price. I can do both of my bikes and not have to order again. A good quality set of tubes for a decent price. I don't like to go too cheap on something like this. I don't want to be let down because I cheaped out on the innertubes on my bike so now I'm walking home from 13 miles away. The valves are long enough for a deeper rim but work OK on my skinny one. We'll see how they last. The tubes that came in my bike are still good, but I'm putting on new tires so I figure I should do the tubes as well.

Works and fits great on my tires!

At the time of this posting, this four pack is selling for $25.95, making each tire less than $6.50! This is a great option to keep in your bike bag and around your garage for the occasional flat. The low price means you won't mind replacing them every 5 years to make sure your spare tires are fresh and reliable. I would recommend picking up a pack to make sure you're never stuck out on the road without a way to get home.

These replacement bike tubes worked perfectly to replace the existing tubes in my bike. The presta valves are well built and sturdy, so I have no concerns about leaking from the valve. The rubber feels like it is good quality and not too thin, therefore I expect these to last as long as the original tubes in my bike did … time will tell. They were the correct dimension, easy to install, and a great price, so overall a great value. Exceeded expectations for that price.

These tubes are as good as similar items from name brands. The tube it self seems solid. the rubber is thick. the valve has a good construction and seems sturdy. I'm not a bike professional. i'm your typical week-ender biking with the family person. If i have a flat, I can now quickly swap a tube without having to repair on the spot.

The quality of these tubes is great. Definitely less punctures using these than other brands I have. These are a great price too! Holds air well.

Pas encore posé,mon destrier a besoin de réparation,je ferai une mise à jour, lorsque je ferai du milage avec ces nouvelles chambres à air , elles ont l'air correct,le temps me le dira .
