These Duro inner tubes come in one width range (2.1" - 2.4") and in 1 valve length (33mm). The 2.1" - 2.4" width is super accommodating. These inner tubes can be used to tire widths between 2 inches and 2.4 inches. That's a huge range!
One thing we have discovered is that there are only a handful of bicycle inner tube manufacturers. 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. This is great for you because you'll be getting a high quality tube at a super reduced price. Nearly nowhere else can you buy an inner tube for such a low price anymore!
