Except that nobody runs a mountain bike tire at 100 psi. And
that's not even considering knobby treads. Are you seriously
trying to argue that mountain bikes have lower rolling
resistance than road bikes??

Now we *know* you're a liar - if you don't like to "torture
myself and others" [sic], you'd have given up posting on a.m-
b years ago.

Probably not, but I'd be willing to bet my 26x1.5
Specialized Nimbus EX Armadillos have less rolling
resistance at full pressure than the 26x1 3/8 crappies on
Mikey's "english"

As the subj line says, we've been talking about mtb's on the
street. With street tires, not knobbies. And I DO run my
1.5" CyclePro & 1.9" Cheng Shin at pretty close to 100.

Scroll back up, and you'll see how we got to this point, CC

I have a Discovery 3. I have had it for nearly 2 years now.
I like it a lot. I use it to ride trails and to go to work.
I replaced the knobbies with some on/off road type tires (k-
rads) for above reason. Much better ride than the knobs for
the trip (3 miles) to work. Yet they still have some tread
for the dirt trails I go to . The trails arent difficult by
any means. So I ride a mtnb on road cause its the only bike
I have, on raod is the only way to get to work plus the susp
makes the ride more comfortable

Right you are. A nice reminder of why it's a bad idea to
bother contributing to MV flamewars: you have to read the
whole damn thread. Mea culpa.

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

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. . .Scroll back up, and you'll see how we got

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