    I have used a 1.75 tube in an NBX 2.5

    The trouble with common sense is it is no longer common

    sold.

    I've heard of flyweight's turning to swiss cheese.....

    one more question. Would a thinner tube (in theory) have less rolling resistance than a regular tube? With everything going around about tubeless being faster. I have heard lightweight tubes behave better.

    ......been on maxxis ultralight 1.9/2.1's for years....

    Yes, in theory. A latex tube would be better yet.
