Collection: 622mm innertubes aka 700c/28"/29er

One of the most confusing wheel sizes in the bike industry is the collection that includes 28", 700c and 29" (29er) in its numbers. Amazingly, all of these wheel sizes share the same rim diameter of 622mm and therefore the same innertubes. It's the width of the tyres that changes which innertube you need to choose. Check the side of your tyre to find the ISO measurement, which will be expressed in the format 622-xx, where xx is the width, in mm, of your tyre size. Then choose an innertube with a size range that includes your size. For example if your tyre says 622-60, then you're in the market for any 622mm innertube that covers the width of 62mm (~2.5") . You'll most likely find this in the '29er' section in a tube with a size like 29 x 2.2-2.5". Whereas if your tyre is narrower such as 622-35, then you're looking for a 622mm innertube that covers 35mm wide. This might be expressed in the 28" format such as 28 x 1.5-1.75". Or it may be in the 70cc format such as 700c x 35-43. Clear as mud? Contact us if you need any help.
