Tube sizes
I need new tubes for both of my bikes. How do I determine the sizes I need? Is it the same as the tire size? I've heard some folks even say the size doesn't really matter.
Some advice, please?

Would I be okay to use a size within the same block in this chart?

The tube's diameter needs to be the same as the tire, like a 27" for a 27". But it's OK for the tube's cross-section to be slightly smaller than the tire, like a 1 1/8" for a 1 1/4". The tube will stretch to fit the tire. Avoid a tube that has a larger cross-section than the tire, this can cause wrinkles in the tube and make it hard to mount the tube without serious problems.

Schwalbe tubes are indeed expensive. Try something cheaper.
