I am new to biking. What does double butted mean when talking about tubes? Are they special or something? Lighter or flatproof maybe? All I was told is to make sure I get the right valve when getting new ones. Is there more to it than that?

Double Butted refers to the frame tubing, not inner-tubesCima Coppi

A double butted tubeset in a frame is where the wall thickness of the tube is increased at the ends of the tube for rigidity at the joint.

What you need to be concerned with for inner tubes is whether or not your rims take presta of schrader valves. Otherwise, you'll want to choose between normal or thorn resistant tubes for your wheels.

Felix, there is some confusion as to whether you are talking about inner tubes or frame tubes.

Have a nice holiday!

they grow on trees like apples and flowers need longer valve stems to be pollinated properly.
