No, he's trying not to admit that Mike Vandeman is right.

..As the subj line says, we've been talking about mtb's on the street. With
..street tires, not knobbies.

But they are also WIDER than 10-speed & 3-speed tires. More rubber on the
ground.

And I DO run my 1.5" CyclePro & 1.9" Cheng Shin
..at pretty close to 100.

..Now we *know* you're a liar - if you don't like to "torture myself and

Telling the truth is enjoyable. You should try it sometime.
