Duro Mountain Presta Valve Inner Tube

Believe it or not, 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  get a high quality tube at a great price. Nearly nowhere else can you buy an inner tube for such a low price. Stop getting gouged at the counter and buy your tubes in bulk from Jenson USA. 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.

Features

  • 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
  • Please note: 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.

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.

Great value!
For the purchase price you simply can't beat it. It's always a good idea to have a few spare tubes in the shed and a couple with your riding pack. I usually grab a couple every time I purchase from Jenson just in case.

Good, durable, cheap tube.
Seem a little heavy, but a tube is a tube and the price is right. No durability issues as compared to any other tube.

It's a tube and it works. Can you really want more? It comes is a plastic airtight bag instead of a box. Which makes it a little more inconvenient if you want to stock up and stack them all nicely. But that's my only nitpicky complaint.
