Road wheel rim and tire widths have grown larger in recent years, so I bought a set of Conti tubes sized 25mm-32mm to cover various wheel/tire combinations. The 42mm valve length is adequate for most non-racy rim depths. These tubes are heavy (135g each on my Park scale) and butyl always feels more sluggish than latex, so definitely not the best choice for competition but perfectly adequate for commuting or everyday riding.
Just what you need when doing a new build, trying a new/different set of wheels, put them together and see if they work then just leave them together for the next time you need them. Already to go.
I'm always happy with conti tubes. Hard to beat buying them in bulk.
Good tubes I can replace fast and patch the punctures later
These are good tubes for the price.
I have always preferred Continental tubes. Great product, good value, no problems in quality. They always last longer than the "other" made in...tubes. And on occasions, you get a sticker with them.
42 mm are hard to find. Continenal tire & tubes are not from China
Have only needed to use one so far.
Seems fine. But stay tuned.
We'll see how durable it proves to be.
Tubes for my bike. Easy to install great performance.
You know what you are getting. Solid. Dependable.
These tubes have removable valves which allows me to add sealant to the tube. Between all my bikes/wheelsets, in addition to tubeless and tubed, I now run a set of hybrids.
They're black, they're made of rubber (or rubber-like) substances, and they're designed to hold air. Best of all, buying as a 5-pack ensures I won't have a flat all season long!
The valve on tube was defective. I had to replace the valve on the road. Tube was fine.
I tried cheapo tubes from Amazon a while back and every one failed- I'll be sticking with these from now on.
good tubes, easy to mount, ,and when on sale in a 5 pack are a good deal
All my bikes and in my bike pack. Great tubes never a problem.
