Duro Mountain Presta Valve Tube

Duro inner tubes come in several widths and diameters. The varying widths and diameters are super accommodating. These inner tubes can be used to tire widths between 1.0” - 1.5” & 2.1” - 2.4”. That’s a huge range! Buy more than you think you'll need and keep a few in your bag as spares.

One thing we have discovered is that there are only a handful of bicycle inner tube manufacturers across the globe. Many, if not all inner tubes, come from a small handful of suppliers in Asia. This essentially means that no matter the tube brand, we’re all riding the same tubes.

Thus, we've sourced these tubes direct from the manufacturer and cut out the middle man, passing the savings along to you. This is great for you because you’ll be getting a high quality tube at a great price. Nearly nowhere else can you buy an inner tube for such a low price anymore. Stop getting gouged at the counter and buy your tubes in bulk from Jenson USA!

  • Wide Width Range
  • Compatible with Tubeless and Non-Tubeless Rims
  • High Quality Butyl rubber construction
  • Threaded Valves are included to help keep valve in place
  • Valve Cores are NOT removable
  • Choosing the Correct Tube:
    Choosing the correct tubes for your tires is crucial to the proper performance of your bicycle. If you need help, please call or chat with our Gear Advisors for assistance.

  • Step 1: Find the wheel size, or diameter for your mountain bike. It is usually printed on the tire. (26”, 27.5"/650b, or 29”. If your tire says something else, such as 700 x 23c, you will need to look at our Road tube selection.
  • Step 2: Choose the correct width. If your tire says 29 x 2.25", your tire is 29 inches in diameter and 2.25 inches wide. You can then use a tube labeled 29 x 2.1-2.4". Tubes fit a range of tire widths. Make sure your width is within the tube's range. Do NOT use a tube size not labeled for use with your tire.
  • Step 3:Select a valve stem length that will clear your rim by at least a few centimeters to clear your pump head for easy inflation. Measure your rim depth with a ruler, then simply subtract the depth (vertical thickness) of your rim in millimeters from the valve length. It should be at least 20mm, preferably around 30mm. If it is below that measurement, it will not fit your rim. You will need to buy a tube with a longer valve stem.

Tubes that work
These tubes are very affordable, and they do what you expect them to do. -hold air. My only complaint is with the packaging. The first ones I ordered came in a Mylar looking bag. when I ordered a different size, it came in a clear plastic bag and didn't tell you what size it was. Obviously, I know what I ordered, plus the packing slip tells you what it is. But, what if you ordered two different sizes on the same order? For the price, I can live with that little annoyance and I still give them 5 stars.

PROS: Hold Air

CONS: Packaging

BEST USES: Mountain Biking, Casual Riding

Great Price, works as advertised.
Just a basic tube, I've gone though several of these over the years (no fault of the tube, just bad luck) and have had no complaints.

They do what they're designed too with no fuss or headaches.

cheap tube but works
its a tube. what else is there to say? its cheap, which helps and hurts. its got quite a bit of rubber actually which makes me think they will last a while but its also slightly heavier if youre worried about those things. im not personally and would much rather not ever get a flat again. hoping they keep lasting but so far so good on some technical single track trail. most dependent on the tire anyway.

PROS: Durable

CONS: Heavy

I've tried the Duro road tubes and Duro road tires and both have been great products especially at the price that Jenson offers them at. Hopefully the mountain tubes will perform as well as the road tubes.
