What's the difference between progressive and flat suspension adjustment? Sometimes I ride with my wife.

For street riding there is no need for the flat link. The progressive link essentially increases the resistance on the shock the deeper into the stroke you get. It helps compensate for a second rider. When on the track you want a linear link to keep your suspension from getting to stiff at the bottom of the stroke. Essentially the racing link gives you a more linear pressure through out the entire stroke

The stiffer the shock gets under load essentially begins to take away from the suspensions ability to utilize the tires grip to its maximum. The smoother a shock can react to input under max load the less strain there is on your rear grip. For example if you hit a bump on corner exit hard on the gas a linear set up will help with maintaining traction, while a progressive setup may react more harshly causing the rear tire to loose traction. A rear tire has the same amount of grip no matter what. It's the links job to maximize peak pressures and give you the maximum compensation to limit peak strain on a tire while increasing overall consistancy

The disadvantage of using a linear link is while your setup will be better by yourself, it will be further off when riding double and you run into the potential of bottoming out your rear suspension which would be worse than simply getting stiffer the closer it gets to bottoming out... hope all that rambling made sense haha

Ok thanks
