AR-PRO Bicycle Tubes Race 28 700x20-25C 700x32-47C Bike Tube, 700C Inner Tube with Presta Valve Super Value Bundle (Pack of 6 Tubes & 2 tire Lever)

Good tubes, bought a 6 pack 5 years ago, still somehow have them. I run gatorskins so not many flat tires mostly pinch flats but only have gone through 3 in that time, just replaced another yesterday. Fit easily and hold pressure as well as any of the Cannondale tubes I've used. Probably a little heavier than performance tubes but who cares when you're just going out on 50 mile training rides.

best deal I found on tubes, so much cheaper than buying individually.

1st tube blew up on me after it was inside the tire, the second tube inflated okay, I hope the rest are in good shape, I would hate to be on a ride and have that replacement not work.

Great tubes used the 700x25c on a fulcrum s4 23mm rim and continental 3 25mm tires. They usually last me for about 1 year and 6month on average. Riding 3 time a week for about 30 to 40km each ride. I would have two spare tubes on my on 60km+ rides for quick puncture replacement. And I'll patch the tubes when I get home. I've only recently started patching my tubes so I'll say the 6 pack of tubes may last an extra 6 months before I need to buy another bundle.

Nothing more needs to be said. They work and they’re cheap. I wouldn’t waste money on “better tubes” unless you’re running aluminum rims and want to use latex. But if you’re using carbon wheels these are perfectly fine

5 stars. TLDR: tube withstood a lot of abnormal friction and heat and still didn’t pop or leak. Nice tubes. I Haven’t had these for long but was riding yesterday in the heat with the bead of my tire not seated properly. The tire was bulging out exposing the tube partially, which was rubbing against the brake. This was my fault for not double checking before heading out. constraint, I rode the bike like that for maybe a couple miles until the thing had swollen to the point I couldn’t go any further. I reset the bead today and was able to use the same tube and tire without any problem today. I’m impressed as when that’s happened before I’ve usually had to discard both the tire and tube. I actually had a blowout last time. Anyway, 5 stars to these tubes and continental GP 5k tires.

Excellen item

I should have listened to the poor reviews. Since I started using these tubes I have had 5 flats in as many weeks. I don't know if it is bad rubber or bad manufacturing. They all seem to develop small leaks within several days. No blow outs. Just flat after sitting for a few hours. This is NOT user error. I have changed many bike tires in my day and I'm old now. Spend a little more and save yourself a LOT of frustration. I will not buy these again!

Excellent produit et excellent prix!

My bike came with half dozen of MEC tubes, I used to have flat every two days. Since I bought these I haven’t had flat for 2 weeks now, same routes. So far so good. I will update this review if anything changed. Go for it, it’s thicker also than some brands

Don’t even bother, 2 had holes in them and 2 were bulging, and they were all so hard to install. Waste of time and money. As if the seller is looking through trash at a bike retail store and selling used tires. Wouldnt be surprised if that were true

J'avais besoin de deux chambres à air, mais le kit se fait en 6. Parfait, j'aurai des "spares"! L'installation a été facile, se gonfle bien et la première sortie ne m'a pas permis de détecter de fuite ou quoique ce soit. Je recommande l'achat.

I order it and received it, Did not get cancelled. Which las time with another seller it was cancelled. This order worked.
