I was just wondering what tube size is best for Panaracer Fire XCs 2.1" On Supergo there are tubes for 1.9-2.125, as well as 2.1-2.5, and then on pricepoint are some tubes for 1.9-2.2. So any recommendations? I'm ordering tonight so I need advice :)

Thanks

Ummm Yeah the size you need is in the fit range of either tube. Where's the issue?

Well I was only wondering if people prefer a tube that works with larger diameter tires (less pressure on the tube no?) or a smaller tube which is at it's maximum pressure.

The smaller tube will weigh less, but will be more susceptable to smaller thorns, glass....etc. Think of a ballon. The more you inflate it, the thinner it becomes. If you want to have better flat protection, go with the bigger tubes.

I never thought of that......you learn a new thing everyday at BF. I'm getting bigger tubes.

Interesting... I would get the smaller one, it shouldn't get stretched thin as it will be close to it's original shape in a 2.1 tire and weigh a little less. The bigger might be a little more durable though...
