Hello i have a 2011 diamond back overdrive. I need to know what size tube to buy. Well first it is a 29er. On the rim its says 700c 28-38c. Remember the bike is classified as a 29er. And next to that it says 622 times 20. Finnaly on the tire it says 29 52/52. Very confused. I just want to know what tube size to buy. Please help. Thank you

A tube for a 29x2" tire.

A tube for 700 x 35-38 would probably work just as well. Your tires are undoubtedly 29x2.0 or 2.1.

If you care to give it a read, this will explain a lot about the tire sizes and what they mean. This also shows why there are two sets of numbers for the same size.
