Well, after using a cross bike (with 42c tires) as a MTB --yes, even on some rather technical stuff! -- I just bought my first FS MTB (Giant Warp '06). First, how exactly does the suspension effect positioning, relative to a road bike fit? On my first try, it appears I need the seat a bit higher and much further rearward -- at least 2 cm -- in order to mimic the same position -- roughly heel-on-pedal and knee-over-pedal -- as on my road bike. Does this sound right, or do I need to set it up differently? Also, how would the seat-to-bar distance compare with the drop bar setup? (The distance from tip-of-seat to the road bar is 53 cm . . . should this be the same for the MTB?) Next, what kind of tire pressure is recommended for my 2.1 clincher tires (I weigh about 165 lbs.)? Also, on the rear shock -- coil spring -- it says to increase the pre-load by "turning the knob clockwise . . ." Is this while looking from the front or the rear of the spring?
