Hi, I broke my Schrader valve the other day and need a new tube for my Cannondale Road Warrior 2 (2008).

Here are the specs of the tires:

Tires Vittoria Randonneur, 700x28

Do I need to buy a specific size tube or will any 26" do? (Does it matter if it's 26x1.6 or 26x1.75, etc.?)


Thanks in advance!

If the tires are 700 x 28 you need a 700 tube that has a size range including a 28. A 26 inch tube is not compatible with a 700 mm wheel and tire.

700 is 29", not 26". Regardless you need a tube marked as 700, not 29".

A 700 x 18-25 will do fine.

Actually 700 mm = 27.56 inches but a 700 mm bicycle wheel is smaller than a 27 inch bicycle wheel because of the difference in standard measurements. But it's still too big for a 26" tube.

I was not aware that 700c denoted 700mm. Need to brush up on Sheldon's article.
