I am brand new to mountain bikes.
Went to test ride a couple, Gary Fisher Cobia 29er, $900.
Specialized Rockhopper 29er, $900.

I liked both, but the salesguy said the suspension on the Cobia was better.
But what I don't understand is that both suspensions had a little dial that said "lockout".

The Rockhopper was solid with no movment when locked out.
The Cobia still compressed a little even when locked out.
Is that normal?

I wanted to ride with cross tires on the paved road at times, so I think I would want full lockout for that, wouldn't I? Is the Cobia no good for paved road riding since it won't lockout completely?
