I have fancy new full-suspension bike and both shocks have this strange setting, called
Rebound. It's a red dial, beside the blue CTD lever.
Increasing it makes the shock less responsive to small obstacles. Thus, pedal bob is reduced. However, if I max it out, the shock becomes so stiff, that even jumping onto the saddle (the bike is stationary) from quite some height doesn't move it a bit.
What are some guidelines to tune my fork and rear shock for the terrain that I ride in and for my mass?
My rear shock has CTD. Why would I ever want to limit the travel and sustain high pedal bob, when I can just increase the rebound and enjoy efficient pedaling?
It is known from Linear systems, that a suspension can roughly be modeled by
m*a + b*v + c*s = Fs, where m - mass a - second derivative of position with respect to time b - damping coefficient v - first derivative of position c - spring coefficient s - position Fs - fore on the suspension element.
rebound the same as the coefficient
