3. Rebound Adjustment. All K2 Lithium shock units are equipped with rebound adjustment. Rebound is the
movement of the shock unit from a compressed mode to an uncompressed mode. Rebound damping controls
the speed at which the shock returns to the uncompressed position. While riding, the shock unit is constantly
moving between compressed and non-compressed modes. Rebound damping is adjusted by rotating the
rebound adjuster knob (fig. 33). Clockwise rotation toward the “+” sign provides greater damping, while “-“
applies less damping. More damping means slower rebound. The proper rebound setting is a personal
preference and varies upon your weight and riding style. Experts agree that rebound should be as fast as
possible, without kicking back, or bucking the rider from the saddle when experiencing larger bumps.
K. Attack Set-Up Instructions
1. Spring Preload Adjustment. To receive the best performance from your K2 Attack, it is necessary to adjust the
suspension.
b. What is Sag? “Sag” is the amount a shock compresses (or sags) when you sit on the bicycle. Increasing the
spring preload will make the shock sag, or compress less. Decreasing the spring preload will make the shock
compress, or sag more. Sag should equal 25% of the shock stroke for most usage. You will get the best
performance if you achieve the proper amount of SAG with one turn of preload.
c. Adjusting the Sag. The shock stroke of the K2 Attack varies from size to size.
•
The shock stroke of the SM/MD Attack is 1.125”/28mm
•
The shock stroke of the LG/WB Attack is 1.5”/38mm
•
Recommended SAG for the SM/MD is 0.23”/6mm
•
Recommended SAG for the LG/WB is 0.3”/8mm
In general, the following procedure would allow you to determine the sag for any shock unit.
