What I understood about North Shore riding is that it is a very dynamic process. I find that I constantly do little things based on the terrain situation that are not always noticeable from the side:
- shifting back and forth
- slightly pulling up on the handlebar with coordinated push on a pedal
- lowering and raising the seat
- switching to the appropriate gear to accommodate the terrain situation
- leaning the bike
- putting more weight in different places
- lifting from the seat (60%-40% weight distribution or so) or standing altogether
- doing or not doing many other things that I should or should not
